Data Warehouse and Data Mining

Data Mining Extraction of useful information from data sets.  Data mining serves to find information that is hidden within the available data.
Data Warehouse An information repository from which queries and analysis may be made.
KDD Knowledge Discovery in Databases.  A synonym for data mining.

Decision Support

Decision Support System A program data which assist in analysis and decision-making. 
Dempster-Shafer Theory A belief maintenance system that considers evidence from a number of sources, maintains information on the evidence, and combines the pieces of evidence to produce a decision.

Distributed Computing

Distributed Computing Environment (DCE)  Computer networking environment that consists of many integrated components working together.
Middleware Also called "enabling technology."  It means that the component is not intended to exist alone.  The DCE is middleware.
Secure Core Refers to the Threads, Remote Procedure Call (RPC), Cell Directory Service (CDS), Security Service, and Distributed Time Service (DTS) components of a DCE.

Expert Systems

Backward Chaining A problem-solving procedure that starts with a statement and a set of rules leading to the statement and then works backward, matching the rules with information from a database of facts until the statement can be either verified or proven wrong. 
Case-Based Reasoning (CBR) A problem-solving system that relies on stored representations of previously solved problems and their solutions. 
Expert System A type of application program that makes decisions or solves problems in a particular field by using knowledge and analytical rules defined by experts in the field. 
Expert System Shell A software package that facilitate the building of knowledge-based systems by providing a knowledge representation scheme and an inference engine. The developer adds domain knowledge. 
Forward Chaining A problem solving procedure that starts with a set of rules and a database of facts and works to a conclusion based on facts that match all the premises set forth in the rules. 
If-Then Rule Describes a problem situation and the action an expert would perform in that situation. 
Inference Engine The processing portion of an expert system. With information from the knowledge-base, the inference engine provides the reasoning ability that derive inferences (conclusions) on which the expert system acts. 
Knowledge Acquisition The gathering of expertise from a human expert for entry into an expert system. 
Knowledge-Based System A system that uses stored knowledge to solve problems in a specific domain. 
Knowledge Representation The notation or formalism used for coding the knowledge to be stored in a knowledge-based system. 
Rule Base A set of If-Then rules.

Forth Programming Language

Dictionary List for words and their definitions -- address and parameters. Almost the entire Forth program is contained within the dictionary. 
RPN Reverse Polish Notation Also called postfix notation, is often used on a stack-based machines. The values or operands are placed on the data stack and once the operation is selected, the resulting value is returned on the stack. 
Stack Manipulation Operations in a RPN machine are done to values already on the data stack. Operations such as swap and duplicate allow manipulation of the values on the stack. 
Vocabulary This structure contains a list of variables and related words. Words in one vocabulary may not access to word in other vocabularies thus allowing data hiding. Used as a command, vocabulary creates a new vocabulary. 
Word This is the Forth terminology for a command enabling the hiding data in structures called vocabularies.

Fuzzy Logic

Fuzzy Associative Memory A software structure that collects fuzzy sets, works with them, and produces an output that assists in decision making. 
Fuzzy Logic A form of logic in which variables can have degrees of truth or falsehood. 
Fuzzy Set A set whose elements have degrees of membership. 
Membership Function The mathematical function which defines the degree of an element's membership in a fuzzy set.
