Jess, a rule engine for the Java platform, is a superset of CLIPS programming language, developed by Ernest Friedman-Hill of Sandia National Labs. It was first written in late 1995. It provides rule-based programming suitable for automating an expert system, and is often referred to as an expert system shell. In recent years, intelligent agent systems have also developed, which depend on a similar capability.

  • Jess, a rule engine for the Java platform, is a superset of CLIPS programming language, developed by Ernest Friedman-Hill of Sandia National Labs. It was first written in late 1995. It provides rule-based programming suitable for automating an expert system, and is often referred to 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. Jess can be used to build Java servlets, EJBs, applets, and full applications that use knowledge in the form of declarative rules to draw conclusions and make inferences. Since many rules may match many inputs, there are few effective general purpose matching algorithms. The Jess rules engine uses the Rete algorithm.

  • JessはルールエンジンのためのJavaプラットフォームである。CLIPSプログラミング言語の上位互換であり、サンディア国立研究所の Ernest Friedman-Hill が開発した。1995年末ごろ最初の版が完成した。 エキスパートシステム開発自動化に適したルールベースのプログラミング言語であり、しばしば「エキスパートシステム・シェル」と呼ばれる。近年、知的エージェントと呼ばれるシステムも開発されているが、それと同様の機能を持つ。 Jess は手続き型パラダイムではなく宣言型パラダイムであり、「パターンマッチング」と呼ばれる処理によって規則群を事実群に適用する。規則は事実群に変更を加えたり、何らかの Java コードを実行したりする。 Jess は、宣言型規則の形で知識を使って結論や推論を導くタイプの Java のアプレットやアプリケーションを構築するのに使える。多くの規則が多くの入力にマッチするが、効果的な汎用マッチングアルゴリズムは少ない。JessのルールエンジンはReteアルゴリズムを使用している。 なお、オープンソースではない。
  • Jess是Java平台上的规则引擎，它是CLIPS程序设计语言的超集，由Sandia国家实验室的Ernest Friedman-Hill开发。它的第一个版本写于1995年晚期。 Jess提供适合自动化专家系统的逻辑编程，它常被称作“专家系统外壳”。近年来，智能代理系统也在相似的能力上发展起来。 与一个程序中有一个只运行一次的循环的指令式編程语言不同，Jess使用的宣告式编程通过一个名为“模式匹配”的过程连续的对一个事实的集合运用一系列规则。规则可以修改事实集合，或者运行任何Java代码。 Jess可以被用来构建使用规则定义形式的知识来推倒结论和推论的Java Servlet、EJB、Applet和应用程序。因为不同的规则匹配不同的输入，所以有了一些有效的通用匹配算法。Jess规则引擎使用Rete算法。
