Jess Programming Language
Jess is a rule engine for the Java platform that was developed by Ernest Friedman-Hill of Sandia National Labs. It is a superset of the CLIPS programming language. It was first written in late 1995. The language provides rule-based programming for the automation of an expert system, and is frequently termed as an ''expert system shell''. In recent years, intelligent agent systems have also developed, which depend on a similar capability. Rather than a procedural paradigm, where a single program has a loop that is activated only one time, the declarative paradigm used by Jess continuously applies a collection of rules to a collection of facts by a process called ''pattern matching''. Rules can modify the collection of facts, or they can execute any Java code. It uses the Rete algorithm to execute rules. License While CLIPS is licensed as open source, Jess is not open source. JESS is free for educational and government use but a license is required to use JESS for commercial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knowledge Representation Languages
The following list of notable constructed languages is divided into auxiliary, ritual, engineered, and artistic (including fictional) languages, and their respective subgenres. All entries on this list have further information on separate Wikipedia articles. Auxiliary languages International auxiliary languages International auxiliary languages (IAL) are languages constructed to provide easy, fast, and/or improved communication among all human beings, or a significant portion, without necessarily replacing native languages. Zonal auxiliary languages Zonal auxiliary languages are languages created with the purpose of facilitating communication between speakers of a certain group of related languages. Unlike international auxiliary languages for global uses, they are intended to serve a limited linguistic or geographic area. Examples include Pan-Slavic languages, Pan-Romance languages and Pan-Germanic languages. Controlled languages Controlled natural languages are nat ...

Expert Systems
In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of artificial intelligence (AI) software. An expert system is divided into two subsystems: the inference engine and the knowledge base. The knowledge base represents facts and rules. The inference engine applies the rules to the known facts to deduce new facts. Inference engines can also include explanation and debugging abilities. History Early development Soon after the dawn of modern computers in the late 1940s and early 1950s, researchers started realizing the immense potential these machines had for modern society.

Decision Table
Decision tables are a concise visual representation for specifying which actions to perform depending on given conditions. They are algorithms whose output is a set of actions. The information expressed in decision tables could also be represented as decision trees or in a programming language as a series of if-then-else and switch-case statements. Overview Each decision corresponds to a variable, relation or predicate whose possible values are listed among the condition alternatives. Each action is a procedure or operation to perform, and the entries specify whether (or in what order) the action is to be performed for the set of condition alternatives the entry corresponds to. To make them more concise, many decision tables include in their condition alternatives a don't care symbol. This can be a hyphen or blank, although using a blank is discouraged as it may merely indicate that the decision table has not been finished. One of the uses of decision tables is to reveal cond ...

OpenL Tablets
OpenL Tablets is a business rule management system (BRMS) and a business rules engine (BRE) based on table representation of rules. Engine implements optimized sequential algorithm. OpenL includes such table types as decision table, decision tree, spreadsheet-like calculator. History The OpenL Tablets project was started as an in-house development project in 2003 and later in 2006 was uploaded to SourceForge. Initially it was an open-source business rule engine for Java. Starting from version 5 it became a BRMS. Technology OpenL Tablets engine is specially designed for business rules and uses table rules presentation. Table format enforces rules to be structured and format itself is close to tables found in various business documents. OpenL Tablets is based on OpenL framework for creating custom languages running on Java VM. The engine is designed to allow pluggable language implementations. Currently, it uses 2 languages: table structure for rules format and java-like fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prolog
Prolog is a logic programming language associated with artificial intelligence and computational linguistics. Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program logic is expressed in terms of relations, represented as facts and rules. A computation is initiated by running a ''query'' over these relations. The language was developed and implemented in Marseille, France, in 1972 by Alain Colmerauer with Philippe Roussel, based on Robert Kowalski's procedural interpretation of Horn clauses at University of Edinburgh. Prolog was one of the first logic programming languages and remains the most popular such language today, with several free and commercial implementations available. The language has been used for theorem proving, expert systems, term rewriting, type systems, and automated planning, as well as its original intended field of use, ...

Public Domain Software
Public-domain software is software that has been placed in the public domain, in other words, software for which there is absolutely no ownership such as copyright, trademark, or patent. Software in the public domain can be modified, distributed, or sold even without any attribution by anyone; this is unlike the common case of software under exclusive copyright, where licenses grant limited usage rights. Under the Berne Convention, which most countries have signed, an author automatically obtains the exclusive copyright to anything they have written, and local law may similarly grant copyright, patent, or trademark rights by default. The Convention also covers programs, and they are therefore automatically subject to copyright. If a program is to be placed in the public domain, the author must explicitly disclaim the copyright and other rights on it in some way, e.g. by a waiver statement. In some jurisdictions, some rights (in particular moral rights) cannot be disclaimed: fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
