abacus

The abacus is the earliest known computer. I think it was invented by designers in China, Inc. and is still widely used. When I lived in Japan in the 1980s, I often marvelled at the speed with which so many shopkeepers could tally totals with this archaic computer. The design incorporates a simple GUI, but no identifiably cybernetic features. The cost/performance ratio is still one of the best in the industry.

abstract

Picasso Stamp A concept, thought or object not represented by things corporeal. Abstract may also be a representation or reassembly of physical things in a manner that is one or more removes from reality, as in abstract art. Physical things we can perceive through the senses, possibly with the aid of telescopes, microscopes, dyes, etc. Abstract things are ideas that may or may not apply to physical things, but that must be linked somehow in the brain. Since much, or most of what we know is physical, there must be connections between the physical and abstract.

abstraction

A system design feature or capability that permits both composition and decomposition (see cross-reference definitions). Abstraction is one of the most appealing characteristics of object-oriented systems in that it permits processing of objects whose characteristics may or may not be completely known at the time the system is built.

ACID

A transaction standard for database (mostly relational) manipulation that delivers immediate consistency. ACID stands for:
  • Atomicity: Either the task (or all tasks) within a transaction are performed or none of them are. This is the all-or-none principle. If one element of a transaction fails the entire transaction fails.
  • Consistency: The transaction must meet all protocols or rules defined by the system at all times. The transaction does not violate those protocols and the database must remain in a consistent state at the beginning and end of a transaction; there are never any half-completed transactions.
  • Isolation: No transaction has access to any other transaction that is in an intermediate or unfinished state. Thus, each transaction is independent unto itself. This is required for both performance and consistency of transactions within a database.
  • Durability: Once the transaction is complete, it will persist as complete and cannot be undone; it will survive system failure, power loss and other types of system breakdowns.
(from Dataversity: http://www.dataversity.net/acid-vs-base-the-shifting-ph-of-database-transaction-processing/) Some big data standards use distributed models with BASE transactions.

actionable information

Focus EyeInformation that can be acted upon without further analysis. One distinction between "information" and "knowledge" is that information is characterized by associated data elements combined to add meaningfulness, while knowledge is characterized by actionability: the ability to make immediate decisions and take action without seeking additional information or performing complex analyses. As such, the intrinsic value of actionable information is the reduction in time from consumption to realization of value.

API

apisApplication Programmer Interface. I define API as a predefined protocol for connecting two coded objects together for the purpose of information or process exchange. The coded objects may be of the same type, or different, and may be applications or applets, services or microservices, operating systems or solutions or embedded code that controls hardware. This is a very ambiguous term, and yet, as is common with many terms, the definitions cluster closely together. Here is a definition that focuses on programmers working inside solutions: WeboPedia Here's one that emphasizes control systems such as operating systems: PCMag Here's another that dwells on applications or solutions interacting: ReadWrite Kevin Stanton provides a definition of APIs that I think is most applicable in 2016. His definition is published at Sprout Social. “API is a precise specification written by providers of a service that programmers must follow when using that service... It describes what functionality is available, how it must be used and what formats it will accept as input or return as output. In recent years, the term API colloquially is used to describe both the specification and service itself, e.g., the Facebook Graph API.”

Autonomous computing agents are self-managing computer programs, often very small with narrowly focused capabilities defined by the goals of the designers, able to automatically adapt to unpredictable changes in the information space. The information space may be in the physical world (such as agents operating in robots, vehicles, watercraft or aircraft), or in cyberspace. Some malicious bots are designed as autonomous agents, but uses can be benign and highly beneficial as well. Enterprise IT, Software as a Service and other  computing paradigms are becoming much more complex, making their management, integration, upgrade and retirement efforts significant and costly. Autonomous agents may be used to automate some of these activities or sub-tasks, and shield users and technicians from the underlying complexity.

backpropagation

An algorithm that uses errors in the output (discrete differences between the correct output and the actual output) to train an artificial neural system to derive a correct output automatically. Here's an excerpt from Stanford Research Institute International:

The Backpropagation Algorithm

1.
Propagates inputs forward in the usual way, i.e.
  • All outputs are computed using sigmoid thresholding of the inner product of the corresponding weight and input vectors.
  • All outputs at stage n are connected to all the inputs at stage n+1
2.
Propagates the errors backwards by apportioning them to each unit according to the amount of this error the unit is responsible for.
We now derive the stochastic Backpropagation algorithm for the general case. The derivation is simple, but unfortunately the book-keeping is a little messy.
  • $\vec{x_j} = $ input vector for unit j (xji = ith input to the jth unit)
  • $\vec{w_j} =$ weight vector for unit j (wji = weight on xji)
  • $z_j = \vec{w_j}\cdot \vec{x_j}$, the weighted sum of inputs for unit j
  • oj = output of unit j ( $o_j = \sigma(z_j)$)
  • tj = target for unit j
  • Downstream(j) = set of units whose immediate inputs include the output of j
  • Outputs = set of output units in the final layer
Since we update after each training example, we can simplify the notation somewhat by imagining that the training set consists of exactly one example and so the error can simply be denoted by E. We want to calculate $\frac{\partial E}{\partial w_{ji}}$ for each input weight wji for each output unit j. Note first that since zj is a function of wji regardless of where in the network unit j is located,
\begin{eqnarray*}\frac{\partial E}{\partial w_{ji}} &=& \frac{\partial E}{\parti...<br /><br /><br /><br /><br />
...rtial w_{ji}} \\<br /><br /><br /><br /><br />
&=& \frac{\partial E}{\partial z_j} x_{ji}\\<br /><br /><br /><br /><br />
\end{eqnarray*}
Furthermore, $\frac{\partial E}{\partial z_j}$ is the same regardless of which input weight of unit j we are trying to update. So we denote this quantity by $\delta_j$. Consider the case when $j \in Outputs$. We know
\begin{displaymath}E = \frac{1}{2}\sum_{k \in Outputs} (t_k - \sigma(z_k))^2<br /><br /><br /><br /><br />
\end{displaymath}
Since the outputs of all units $k \ne j$ are independent of wji, we can drop the summation and consider just the contribution to E by j.
\begin{eqnarray*}\delta_j = \frac{\partial E}{\partial z_j} &=& \frac{\partial }...<br /><br /><br /><br /><br />
...o_j)(1-\sigma(z_j))\sigma(z_j)\\<br /><br /><br /><br /><br />
&=& -(t_j - o_j)(1-o_j)o_j\\<br /><br /><br /><br /><br />
\end{eqnarray*}
Thus
 \begin{displaymath}<br /><br /><br /><br /><br />
\Delta w_{ji} = -\eta \frac{\partial E}{\partial w_ij} = \eta \delta_j x_{ji}<br /><br /><br /><br /><br />
\end{displaymath} (17)
Stanford Research Institute International Now consider the case when j is a hidden unit. Like before, we make the following two important observations.
1. For each unit k downstream from jzk is a function of zj
2. The contribution to error by all units $l \ne j$ in the same layer as j is independent of wji
We want to calculate $\frac{\partial E}{\partial w_{ji}}$ for each input weight wji for each hidden unit j. Note that wji influences just zj which influences oj which influences $z_k \forall k \in<br /><br /><br /><br /><br />
Downstream(j)$ each of which influence E. So we can write
\begin{eqnarray*}\frac{\partial E}{\partial w_{ji}} &=& \sum_{k \in Downstream(j...<br /><br /><br /><br /><br />
...al o_j} \cdot<br /><br /><br /><br /><br />
\frac{\partial o_j}{\partial z_j} \cdot x_{ji}\\<br /><br /><br /><br /><br />
\end{eqnarray*}
Again note that all the terms except xji in the above product are the same regardless of which input weight of unit j we are trying to update. Like before, we denote this common quantity by $\delta_j$. Also note that $\frac{\partial E}{\partial z_k} = \delta_k$$\frac{\partial z_k}{\partial o_j} =<br /><br /><br /><br /><br />
w_{kj}$ and $\frac{\partial o_j}{\partial z_j} = o_j (1-o_j)$. Substituting,
\begin{eqnarray*}\delta_j &=& \sum_{k \in Downstream(j)}<br /><br /><br /><br /><br />
\frac{\partial E}{\par...<br /><br /><br /><br /><br />
...<br /><br /><br /><br /><br />
&=& \sum_{k \in Downstream(j)} \delta_k w_{kj} o_j (1-o_j)\\<br /><br /><br /><br /><br />
\end{eqnarray*}
Thus,
 \begin{displaymath}<br /><br /><br /><br /><br />
\delta_k = o_j (1-o_j) \sum_{k \in Downstream(j)} \delta_k w_{kj}<br /><br /><br /><br /><br />
\end{displaymath} (18)
Stanford Research Institute International We are now in a position to state the Backpropagation algorithm formally. Formal statement of the algorithm: Stochastic Backpropagation(training examples, $\eta$ninhno) Each training example is of the form $\langle \vec{x}, \vec{t}<br /><br /><br /><br /><br />
\rangle$ where $\vec{x}$ is the input vector and $\vec{t}$ is the target vector. $\eta$ is the learning rate (e.g., .05). ninh and no are the number of input, hidden and output nodes respectively. Input from unit i to unit j is denoted xji and its weight is denoted by wji.
  • Create a feed-forward network with ni inputs, nh hidden units, and no output units.
  • Initialize all the weights to small random values (e.g., between -.05 and .05)
  • Until termination condition is met, Do
    • For each training example $\langle \vec{x}, \vec{t}<br /><br /><br /><br /><br />
\rangle$, Do
      1. Input the instance $\vec{x}$ and compute the output ou of every unit.
      2. For each output unit k, calculate
      \begin{displaymath}\delta_k = o_k(1-o_k)(t_k - o_k)<br /><br /><br /><br /><br />
\end{displaymath}
      3. For each hidden unit h, calculate
      \begin{displaymath}\delta_h = o_h(1-o_h)\sum_{k \in Downstream(h)} w_{kh}\delta_k<br /><br /><br /><br /><br />
\end{displaymath}
      4. Update each network weight wji as follows:
      \begin{eqnarray*}w_{ji} &\leftarrow& w_{ji} + \Delta w_{ji}\\<br /><br /><br /><br /><br />
{\rm where} \quad \Delta w_{ji} &=& \eta \delta_j x_ji\\<br /><br /><br /><br /><br />
\end{eqnarray*}

BASE

Linked DatabasesMost relational databases support ACID transactions, that rely on a single data store (often on a single disk or cluster of a handful of disks. Big Data often runs on dozens, hundreds or thousands of physical disk drives, and use BASE transactions to spread out the data and improve resilience. The improvements come when there are a high volume of concurrent transactions, and when one or more physical drives fail. A transaction standard for database (mostly big data) manipulation that delivers eventual consistency. BASE stands for:
  • Basically Available: This constraint states that the system does guarantee the availability of the data as regards CAP Theorem; there will be a response to any request. But, that response could still be ‘failure’ to obtain the requested data or the data may be in an inconsistent or changing state, much like waiting for a check to clear in your bank account.
  • Soft state: The state of the system could change over time, so even during times without input there may be changes going on due to ‘eventual consistency,’ thus the state of the system is always ‘soft.’
  • Eventual consistency: The system will eventually become consistent once it stops receiving input. The data will propagate to everywhere it should sooner or later, but the system will continue to receive input and is not checking the consistency of every transaction before it moves onto the next one. Werner Vogel’s article “Eventually Consistent - Revisited” covers this topic is much greater detail.

Beyond relational database management systems (RDBMS), online analytical processing (OLAP) and advanced business intelligence (BI), humanity has finally evolved to a technology that doesn't need an acronym: Big Data. Instead, we choose names of children's toys (HADOOP the toy elephant) and confusing word munges (MapReduce) to describe the best new thing in high-performance data access. Big Data not only avoids the pain of endless joins between relational tables that drag most systems to their metaphorical knees, it also provides a single, elegant mechanism for accessing both structured and unstructured data. This is a key to the final answer.

BPM

Computer Program FlowBusiness Process Modeling: Application development methods based on process flow-diagramming that can effectively be automated using high Speed, low code tools and standards including BPMN 2.0 (BPM Notation) and BPEL (Business Process Execution Language). Gartner says: "Business process management (BPM) is a discipline that uses various methods to discover, model, analyze, measure, improve, and optimize business processes.  A business process coordinates the behavior of people, systems, information, and things to produce business outcomes in support of a business strategy. Processes can be structured and repeatable or unstructured and variable. Though not required, technologies are often used with BPM. BPM is key to align IT/OT investments to business strategy (http://www.gartner.com/it-glossary/business-process-management-bpm/).

business intelligence

Rubics CubeMulti-dimensional analytics in business modeling and reporting has an assumed name: business intelligence (BI). A relational database is basically two dimensional with tables and columns in one dimension and primary and foreign keys in another. Multi-dimensional analytics involve "cubes" and "star schemas" that create formal edges binding together different dimensions. Each dimension is defined as a semantic concept with a set of attributes and facts. This muti-dimensionality empowers business analysts with better insights as it permits deeper analytics, advanced filtering and sorting and a variety of views that answer more complex questions than typical reports.

canonical model

Canon in MonacoCanonical models are logical level semantic graphs, and can be used for both data and processes. "Canonical" implies a top-level prescribed set of rules that define orderliness and, when adhered to, oppose chaos. A canonical data model (CDM) defines the core content entities associated with a specific domain, their semantic meanings, attributes, and associations with other elements. A canonical process model describes top-level processes and sequences needed to comply and to accomplish a mission. Both canonical data and process models serve as reference models, forming abstract, general frameworks to support specific implementations.

categorize

When we generalize in the learning process we often place a new thing or concept in a hierarchy along with other like things. For example, when we see an automobile we have never seen before, we might categorize it along with other like automobiles, say, as a sporty model or as a European style. When we lump things together in categories (or classes in object-oriented systems), they can inherit characteristics of other things of the same class (for example FAST and TOO EXPENSIVE FOR ME).

combinatorial explosion

The paradox of choices is a fundamental problem in computational search and problem solving. As the number of possible constraint or solution combinations that one has to examine grows exponentially, even the fastest computers may require excessive amounts of time to deliver acceptable results. This effectively limits a system's ability to solve large problems. As it is, many problems of real interest to us have either a large number of constraints or possible solutions. Traditional "brute-force" searches where each option is compared consume processor time incrementally for each additional option. After a certain number of options, you would simply run out of time. As an example, if you have n constraints or factors for a decision, each with 10 possible options, then you will have all together 10 to the power n combinations of results. The number of combinations grows exponentially as n increases. In chess, a system could examine every possible move and the possible moves that could follow. However, if we limit it to 20 choices per move, then looking ahead 15 moves would require the system to compare 20 to the 15th power, or 3.3x10^19, sequences. If the system manages to examine 1 Billion sequences per second, a brute force search would have to take over 90 million hours or over 10,000 years to make one move. To improve the speed of play, one needs either much faster computers or heuristic algorithms that do not perform exhaustive search but choose which sequences to examine. The combinatorial explosion problem prevented computers from competing with human world champions until suitable heuristic solutions were invented.

concept learning

Learning CycleConcept learning, category learning or concept acquisition/attainment is a distinct type of learning, human or machine, characterized by construction of an associative meaning model. From a psychology wiki, "concepts are the mental categories that help us classify objects, events, or ideas and each object, event, or idea has a set of common relevant features. Thus, concept learning is a strategy which requires a learner to compare and contrast groups or categories that contain concept-relevant features with groups or categories that do not contain concept-relevant features." The set of common relevant features represent associations with taxonomical generalization. Concept learning can go beyond taxonomies to causality, meronomy, identity, time and space, and narrower domains such as geopolitics manufacturing processes.

digital consumability

digital-owl-3Consumability is predictably ambiguous. IBM uses the term to mean "assets available on machines in a LoadLeveler® cluster." but consumability means "a client's complete experience with a technology solution beginning with buying the right product to updating it." This is not what I'm talking about. Digital consumability, in the context of this blog, is a property of digital information involving formats accessible to multiple systems and processes (such as heuristics) that may benefit from it. This means that systems that didn't create it and don't manage it can get it and use it to bring some value. Many Legacy computing systems are unable to adapt their behavior based on consuming external data. But as more "services", micro-services, and cognitive computing systems arise in an IT ecosystem where API's facilitate interconnections between systems, the importance of rich consumable digital information increases, and creates opportunities to add intelligence to existing processes.

Electrical Current

The source of electrical power derived from electrons breaking free and being recaptured. The passing of electrons between atoms in an element or substance causes electrical current. Remember that electrons revolve around the positively attractive nucleus in orbits at various distances. Centripetal force constantly tugs at the electrons, pulling against the attraction of the nucleus. This gives these smaller particles a tendency to detach from the atom. But the attraction force between negative electrons and positive nucleus is normally strong enough to keep them bounded in the atomic orbit. The centripetal force tugging at the electrons increases at greater distances of the electrons’ orbit from the nucleus, and magnetic force between electrons and nucleus weakens. The attraction further weakens for electrons in outer orbits because of a repulsion force from other electrons in inner cells. That explains why electrons in outer most orbit are most loosely bonded with the nucleus and vulnerable to detachment. For some elements and substances, the outermost electrons are so loosely bonded that very little force is needed to detach them from their parent atom. Atoms in their normal state are electrically neutral as they possess an equal number of positive protons and negative electrons, creating balance. But escaping electrons create imbalance, and until the atoms thus deprived can grab a free atom from somewhere, the stable number of protons make the atoms become positively charged. After detaching from parent atoms, electrons move about freely, attracted by whatever force intersects their inertial trajectory. Other positively charged atoms in the vicinity opportunistically   pull in free electrons. In general, the outermost electrons in metal atoms are very loosely bonded, so free electrons are always available in metal, which makes the metal a good conductor of electric current. Water molecules, which constitute a significant portion of the human body, are also very good conductors. Learn about Electricity

Gamma Oscillations

From Nature: http://www.nature.com/nrn/journal/v8/n1/abs/nrn2044.html Gamma frequency oscillations are thought to provide a temporal structure for information processing in the brain. They contribute to cognitive functions, such as memory formation and sensory processing, and are disturbed in some psychiatric disorders. Fast-spiking, parvalbumin-expressing, soma-inhibiting interneurons have a key role in the generation of these oscillations. Experimental analysis in the hippocampus and the neocortex reveals that synapses among these interneurons are highly specialized. Computational analysis further suggests that synaptic specialization turns interneuron networks into robust gamma frequency oscillators.

Garbage In, Garbage Out. This is the arrogance and frailty of early programmers. If the input was not exactly what the computer expected, then it was garbage, and the only possible output would be garbage. For the first several decades of computing, this paradigm stood, much to the consternation of most users. We are beginning to turn a corner in which the computer will attempt to deliver good output even with imperfect input.

graceful degradation

A characteristic of a computational system that does not break when it does not like what you tell it. In other words, a system that may put out something other than garbage when the input would be treated as garbage by more rigid or inflexible systems. In natural language processing systems, graceful degradation is a must because not all people use absolutely perfect language all the time. In fact, few people use perfect language ever.

granularity

This word is important in parallel computing and problem decomposition. When we solve a problem using a divide-and-conquer approach, granularity is the word we use to describe the coarseness or fineness of the pieces after we have divided the problem. The pieces of a computational problem computed on different processors of a parallel machine possess a granularity describing the coarseness or fineness of pieces of code that go to each processor. This is where modularity comes in: the finer the granularity of code modules, the closer we can approach a "knowledge driven" technical ecosystem.

impedance mismatch

ERD - Entity Relationship DiagramObject-oriented programming languages enable developers to build systems, services and applications out of objects that have both data and behavior (methods).   Relational databases store data in tables bound together through primary and foreign keys. Object-oriented programming is based on time-tested software engineering principles while the "relational" paradigm is based on mathematical principles.  Because the underlying paradigms are different the two technologies require an intervening transformation layer to work together seamlessly. "The impedance mismatch becomes apparent when you look at the preferred approach to access: With the object paradigm you traverse objects via their relationships whereas with the relational paradigm you join the data rows of tables. This fundamental difference results in a non-ideal combination of object and relational technologies" (Scott Wambler at Agile Data).

Face it – everything is meaningful! There are contexts in which a thing that is normally very meaningful may lose its importance. Meaningfulness is a measure of interest and relevance that we apply to the thing being considered. In any given context, almost everything in the universe is meaningless.

metonymy

Oval OfficeMetonymy s a form of speech that uses an individual or an attribute as a proxy for a larger object, group or class. Examples include John Doe for an unnamed person (typically male - Jane Doe for female), oval office for the US Presidency, suit for business executive, or the track for horse racing. Metonymy is broader than synecdoche, which is strictly using a part to describe the whole. Metonymy and synecdoche both twist context in ways that only the broader context of the surrounding language can help a person (or machine) discern the true intent of the speaker or writer. synecdoche

modularity

Modularity implies that programs consist of building-blocks of functions that can be assembled as needed to complete the structure. One big advantage of modular code is that computers are good at making copies of code. So if the code is truly modular, you should be able to reproduce it ad infinitum and apply it to any number of different systems with similar functions. This is where granularity comes in: the finer the granularity of code modules, the closer we can approach a "knowledge driven" technical ecosystem.

multi-valued logic

Western societies have long relied on dichotomous logic championed by Aristotle and his successors. Oriental society has traditionally based reasoning on a different form of pragmatism that acknowledges shades of truth and partial falsehoods. Subjective or intuitive analysis of problem constraints often shows that while something is true under most circumstances, it may not be so true if something unexpected enters the equation. Some false things are truer than others. Using multiple truth or confidence values adds flexibility to the reasoning process.

Natural Language Understanding (NLU)

Understanding IntentUnderstanding is the ability to extract meaning. Natural language means one of thousands of symbol systems used by humans to communicate vocally and verbally. Once a word is in the wild it can't be withdrawn. But the creation of speech or writing doesn't guarantee understanding. Understanding is based on an informal agreement between the speaker/writer and the hearer/reader that the symbols in the shared language have specific definitions, and that specific grammatical patterns of phrases and sentences used to express intent and fact enable mutual empathetic collaboration. Even within a single language, different groups divided by age and gender interpret the same words and phrases differently. But as wisdom increases, people become better able to bridge those gaps in understanding. Computers, on the other hand, have never exhibited the ability to understand human intent nor to empathize. Thus, NLU in computers has not yet been achieved at any significant scale. Natural Language Processing or NLP, on the other hand, including basic grammatical analysis and phrase matching is in broad and effective use today January 2020.

normalization

ERD - Entity Relationship DiagramA process used in modeling data, especially in relational databases, to minimize redundancy. Data normalization techniques can save space and improve data quality by simplifying changes to data. See Holowczak's tutorial on how to do it, and Margaret Rouse on what it is. Relational database normalization relies on Primary and foreign keys that link tables together in one-to-one or one-to-many relationships.

First normal form (1NF) is a minimal level of normalization in which the database:

  • contains any number two-dimensional tables with rows and columns named to represent the core object;
  • each table's columns contain data on the attributes of the core object and the column names usually name the attribute;
  • each row or record in each table represents a unique instance of the core object or attribute and must contain at least one value different from any other row (no duplicate rows are allowed);
  • All entries in any column must be of the data type (date fields must contain valid dates and amount fields must contain valid numbers).

Second normal form (2NF) is an intermediate level of normalization in which each column in a table that is not a determiner of the contents of another column, must itself be a function of the other columns in the table. For example, in a "Purchases" table with columns containing "Customer ID", "Product", and "Price", the price would be a function of the customer ID and the specific product and may be derived from a separate "Prices" table.

Third normal form (3NF) is the defacto standard for transactional database modeling (reporting databases are often "denormalized"). 3NF states that all columns in a table not dependent on the primary key should be removed from the table, and placed in a separate table or eliminated. Another way of putting this is that only foreign key columns should be used to reference another table, and no other columns from the parent table should exist in the referenced table.

ODBMS

Database IconObject Database Management System: is object-oriented database system software that treats and models data as objects. Like OO programming systems, ODBMS' provide classes of objects and the inheritance of class properties and methods by subclasses and objects to define the links between different data entities. Malcolm Atkinson et al got the ODBMS ball rolling in their in 1995 paper: The Object-Oriented Database System Manifesto, suggesting database models that seamlessly inter-operate with object-oriented programming languages such as Smalltalk. Database systems typically manage persistence, concurrent threads or processes, secondary storage, recovery and support ad hoc queries. ODBMS' add complex objects, object identity, encapsulation, types or classes, inheritance, overriding combined with late binding, extensibility and computational completeness (see ODBMS Definition).

Open Web vs. Deep Web

The internet has been inhabited by protocols for browsers to read content in HTML (HyperText Markup Language) that create a massive web of interconnected content collectively known as the "world-wide web" (www) or just the "web". The open part is content that is not protected by passwords, and thus accessible to anyone. Some pages on the open web do not permit search-engine access for crawling and indexing, thus making the content harder to find, but nevertheless accessible. TechTarget tells us that "Deep Web content includes information in private databases that are accessible over the Internet but not intended to be crawled by search engines. For example, some universities, government agencies and other organizations maintain databases of information that were not created for general public access.

overloading

Digital Data StreamSome object-oriented programming languages permit reuse of the same function name to perform different functions in different contexts. This polymorphism mirrors polysemy which creates ambiguity in human languages. Function overloading or method overloading, found in programming languages such as Ada, C++, C#, Delphi, D, Java, and Swift, allows creating more than one method with the same name that differ from each other in the type of the input and the output of the function. In operator overloading, or ad hoc polymorphism, different operators have different implementations depending on their arguments. In either case, programmers are required to keep these things straight in their minds and documentation to ensure proper functioning code.

possibility

Something that exists within a framework of laws controlling phenomena, such as the physical universe. We have reason to believe that the laws of physics govern the behavior of things in the universe. If this is true, and if there is no mystical "random" law breaker out there, then there is a threshold above which anything can happen (possibility) and below which nothing can happen (impossibility). This threshold, governed by the laws of physics, known and unknown, in aggregate, may or may not exist. If it does not, the there is no such thing as impossibility. It would be logical to conclude that if nothing is impossible, then the term "possibility" becomes unnecessary. I choose to cling to a notion of order in which the threshold of possibility exists, and can be relied upon to prevent the impossible from ever happening.

possible

Any event or occurence which can happen. In threshold logic, the possibility of any event falling either above (possible) or below the threshold (impossible); nothing can straddle the line. Threshold logic applied to possibility is context-governed; consequently, some events may be possible in some contexts and impossible in others. If nothing is impossible, this does not apply.

programming

Digital Data StreamThe art of translating human thought patterns into automated computer code. I didn't say it was useful. Much of it is not. But the stuff that is can be pretty amazing. "Rather than increasing the number of kids who can crank out thousands of lines of JavaScript, we first need to boost the number who understand what code can do. As the cities that have hosted Code for America teams will tell you, the greatest contribution the young programmers bring isn't the software they write. It's the way they think. It's a principle called "computational thinking," and knowing all of the Java syntax in the world won't help if you can't think of good ways to apply it." (Mother Jones)

programming language

Computer Program FlowA formal language with its own syntax, reserved words (vocabulary) and tools for interpreting or compiling, that allows programmers to author a set of instructions that can be used to accept input, perform processes, and deliver various kinds of output. High level Programming languages are more readable and easier to compose, like human language, and low level languages like assembler and Op Code are less human readable, but great for folks made of highly conductive metals and silicon. The code that specifies the algorithms written in the languages can be interpreted or compiled into executable instructions for a computer.

quantifiers

In formal logic we have two kinds of qualifiers, existential and universal. The backwards capital E is the existential quantifier. It means 'there are some' or 'sometimes' and it modifies the variable it precedes. The inverted capital A is the universal quantifier. It means 'for all' or 'always' and it modifies the variable it precedes. The universal quantifier followed by a negated expression means 'never.' Be careful with the universal quantifier. Truly fuzzy systems imply frugal use or non-use of always or never. Keywords: logic formalism equation multi-valued logic reasoning References: algorithms automata computing formalisms logic rules

random

Flower FractalSomething that is devoid of a regular pattern. In the mathematical definition, it is random because we don't yet understand the laws or formulas that govern it. In other definitions, it is due to its immunity to any law which would force it into a repeating sequence that would constitute a pattern. The existence of the lawless form of randomness is purely theoretical since there is no way to prove that anything is infinitely irregular or unpredictable. Small-scale quasi-randomness (as opposed to pure randomness) is a useful tool, particularly in game theory. Does the Copenhagen Interpretation prove that there is such a thing as randomness?

RDF - Resource Description Framework

RDF is a semantic model using "triples" for data storage, access and interchange, supporting data merging across different schemas. The triples model creates a directed graph that can grow supporting the evolution of schemas over time without requiring all the data interfaces to be changed. The expressiveness of RDF is in the URIs that name the relationships between things as well as the two ends of each link, allowing relational database content and less structured content to be combined, accessed, and shared across different applications. The collection of RDF triples becomes a directed, labeled graph, where the edges represent the named links between each pair of resources, and the resources themselves forming the graph nodes.

register

Register as a verb can be used like "remember". A register (noun) can be a set of digital "locations" that, combined, are treated as a base unit of computing. A byte register is 8 bits in length,  a word 2 bytes, a doubleword 4 bytes and a quadword 8 bytes or 64 bits (commonly in use as a personal computing standard at the time of this writing). The Tortall YASM Manual tells us about Intel CPU architecture: The 64-bit x86 register set consists of 16 general purpose registers, only 8 of which are available in 16-bit and 32-bit mode. The core eight 16-bit registers are AX, BX, CX, DX, SI, DI, BP, and SP. The least significant 8 bits of the first four of these registers are accessible via the AL, BL, CL, and DL in all execution modes. In 64-bit mode, the least significant 8 bits of the other four of these registers are also accessible; these are named SIL, DIL, SPL, and BPL. The most significant 8 bits of the first four 16-bit registers are also available, although there are some restrictions on when they can be used in 64-bit mode; these are named AH, BH, CH, and DH. The 80386 extended these registers to 32 bits while retaining all of the 16-bit and 8-bit names that were available in 16-bit mode. The new extended registers are denoted by adding a E prefix; thus the core eight 32-bit registers are named EAX, EBX, ECX, EDX, ESI, EDI, EBP, and ESP. The original 8-bit and 16-bit register names map into the least significant portion of the 32-bit registers. 64-bit long mode further extended these registers to 64 bits in size by adding a R prefix to the 16-bit name; thus the base eight 64-bit registers are named RAX, RBX, etc. Long mode also added eight extra registers named numerically r8 through r15. The least significant 32 bits of these registers are available via a d suffix (r8d through r15d), the least significant 16 bits via a w suffix (r8w through r15w), and the least significant 8 bits via a b suffix (r8b through r15b). The figure below summarizes the full 64-bit x86 general purpose register set.

Rete algorithm

Rete is latin for net, and it is an algorithm that breaks rules down into left and right sides and treats them as nodes in a network. The following explanation was borrowed from http://www.jessrules.com/docs/71/rete.html "The typical rule-based program has a fixed set of rules while the working memory changes continuously. However, it is an empirical fact that, in most rule-based programs, much of the working memory is also fairly fixed from one rule operation to the next. Athough new facts arrive and old ones are removed at all times, the percentage of facts that change per unit time is generally fairly small. For this reason, the obvious implementation for the rule engine is very inefficient. This obvious implementation would be to keep a list of the rules and continuously cycle through the list, checking each one's left-hand-side (LHS) against the working memory and executing the right-hand-side (RHS) of any rules that apply. This is inefficient because most of the tests made on each cycle will have the same results as on the previous iteration. However, since the working memory is stable, most of the tests will be repeated. You might call this the rules finding facts approach and its computational complexity is of the order of O(RF^P), where R is the number of rules, P is the average number of patterns per rule LHS, and F is the number of facts on the working memory. This escalates dramatically as the number of patterns per rule increases." "The Rete algorithm is implemented by building a network of nodes, each of which represents one or more tests found on a rule LHS. Facts that are being added to or removed from the working memory are processed by this network of nodes. At the bottom of the network are nodes representing individual rules. When a set of facts filters all the way down to the bottom of the network, it has passed all the tests on the LHS of a particular rule and this set becomes an activation. The associated rule may have its RHS executed (fired) if the activation is not invalidated first by the removal of one or more facts from its activation set." "Within the network itself there are broadly two kinds of nodes: one-input and two-input nodes. One-input nodes perform tests on individual facts, while two-input nodes perform tests across facts and perform the grouping function. Subtypes of these two classes of node are also used and there are also auxiliary types such as the terminal nodes mentioned above." [Forgy 1982]

semantic tagging

The process of associating meaningful language markers with digitally stored and delivered information. Championed for the World Wide Web, semantic tagging was initially inline with the text, so each tag could be embedded in the HTML at the beginning of a document or with the text to which the tag applied. This is "tight coupling" because they are inextricably connected and to edit the tags, you have to edit the entire document, and possibly redeploy it. Metadata in DatabaseThen came Search Engine Optimization (SEO) in which the tools provide tagging which is separate from the document but still bound to the page using tools such as PHP or derivatives WordPress or Drupal. Finally, the loosely coupled strategy of using ontologies to perform the tagging made it possible to have completely separate processes for managing metadata and managing the content. This is especially valuable for tagging material you want to leave as is, such as a Shakespeare play or the Bible, a recorded Boston Pops concert, or a digital image of an impressionist painting or MRI of your heart. The tag lives separately and points to the associated content using a URI or URL.

semantics

Language StrataI define semantics from a business perspective as "technology formalisms that provide structured representations of meaning and context to add business value to automated processes" that formerly or currently require human interpretation to establish such connections. Other definitions include:
  1. The study of meaning and roles in words and sentences.
  2. Semantic constraints tell us what roles words can and cannot play. Some roles are AGENT, INSTRUMENT, OBJECT, and ACTION. To be an action, a word or phrase must be a verb. Agents and objects are nominal.
  3. An argument that relies on word meanings in isolation without capturing the broader context

sensory transduction

There are two main senses: 1) (From the UniProt knowledge base) Protein involved in sensory transduction, the process by which a cell converts an extracellular signal, such as light, taste, sound, touch or smell, into electric signals. 2) The process in which any cell converts the energy in a stimulus (such as propagated action potentials) into a change in the electrical potential across its membrane. Definition 2 may not technically be "sensory" transduction, but generic transduction. My suspicion is that there is no difference in the physical mechanism between receptor cells, which are associated with sensory stimuli, and all other neurons, which may be participating in more abstract cognitive functions largely independent (if that is possible) of immediate sensory input.

Service-Oriented Architecture

A systems design/architecture strategy with more separate, reusable programs designed as services, rather than fewer large applications. These smaller services are normally much simpler than large applications, with functionality limited to easily defined capabilities. The  services are often invoked through a service bus using a predefined mechanism governed by a contract. This is an important evolution in computing in that it brings us a step closer to the end of code that is independent of knowledge, and closer to knowledge-driven functionality (code).

short-term memory

Also called working memory, short-term memory is where (or how) we store temporary representations of facts or objects for immediate processing.

SME - subject matter expert

Isixsigma suggests that an SME (not to be confused with a small to medium-sized enterprise) is the "individual who exhibits the highest level of expertise in performing a specialized job, task, or skill within the organization." In fact there can be multiple SMEs in each area, though this is often not the case. Organizations that have the luxury of appointing data or process stewards or woners may formalize this role in named persons, but subject matter expertise, while clearly the most important knowledge asset in a company, is seldom formalized effectively. Isixsigma goes on to say "An SME might be a software engineer, a helpdesk support operative, an accounts manager, a scientific researcher: in short, anybody with in-depth knowledge of the subject you are attempting to document. You need to talk to SMEs in the research phase of a documentation project (to get your facts straight) and you need to involve them in the technical validation of your drafts (to make sure that your interpretation of information matches theirs)."

SOA

Service-Oriented Architecture is a software development and deployment model in which, instead of huge programs with huge modules, you break down your processes to a finer granularity and code for efficiency through compactness and reusabiluity. This reference sums it up nicely: "SOA is a style of architecting applications in such a way that they are composed of discrete software agents that have simple, well defined interfaces and are orchestrated through a loose coupling to perform a required function. There are 2 roles in SOA- a service provider and a service consumer. A software agent may play both roles. SOA is not an entirely new concept – however, this article mainly focuses on SOA as implemented with web services." (StackOverflow: soa-in-plain-english)

synecdoche

All HandsSynecdoche is a form of speech in which you use a part to refer to its whole or vice-versa. Here are some good examples from World Wide Words: "You use this when you speak of a part of something but mean the whole thing. When Patrick O’Brian has Captain Jack Aubrey tell his first lieutenant to “let the hands go to dinner” he’s employing synecdoche, because he’s using a part (the hand) for the whole man. You can also reverse the whole and the part, so using a word for something when you only mean part of it. This often comes up in sport: a commentator might say that “The West Indies has lost to England” when he means that the West Indian team has lost to the English one. America is often used as synecdoche in this second sense, as the word refers to the whole continent but is frequently applied to a part of it, the USA." Synecdoche  is narrower than metonymy, which may use an individual or an attribute to describe an object, group or class. Metonymy and synecdoche both twist context in ways that only the broader context of the surrounding language can help a person (or machine) discern the true intent of the speaker or writer. metonymy
