| | Jess programming language: Just the facts... |
 | | Jess, a rule engine for the Java platform, is a superset of CLIPS (additional info and facts about CLIPS) programming language ((computer science) a language designed for programming computers), developed by Ernest Friedman-Hill of Sandia National Labs (additional info and facts about Sandia National Labs). | | | Since many rules may match many inputs, there are few effective general purpose matching algorithms. | | | Rather than a procedural paradigm, where a single program has a loop that is activated only one time, the declarative paradigm used by Jess matches a rule with a single fact specified as its input and processes that fact as its output. |

| | Upon the creation of a rule, the corresponding expression is parsed and a binary tree is constructed to represent each element of the expression. | | | Changes may be made to the rule engine implementation to enable event generations upon the arrival of other information. | | | Note that this implementation supports the inclusion of a maximum of one group name per rule expression, the result is undefined. |

| | Getting Started With the Java Rule Engine API (JSR 94) |
| | Because the JSR 94 reference implementation is built as a wrapper over the Jess rule engine, you will need Jess 6.1a3 or later in order to work with the reference implementation. | | | A solution is to have a rule engine, which is basically a set of tools that enable business analysts and developers to build decision logic based on an organization's data. | | | The power of business rules lies in their ability both to separate knowledge from its implementation logic and to be changed without changing source code. |

| | Rule engine - Wikipedia, the free encyclopedia |
| | A Rule Engine is a software system that helps managing business rules. | | | There are a range of rule engine design strategies available--from custom language-based interpretive approaches to XML-based code generation approaches. | | | Rule Engine or Inference Engines are the pluggable software components that separate the business rules from the application code. |

| | Jena 2 Inference Support |
| | The default rule engine is based on the standard RETE algorithm (C.L Forgy, RETE: A fast algorithm for the many pattern/many object pattern match problem, Artificial Intelligence 1982) which is optimized for such incremental changes. | | | Such a rule would work but every goal would match the head of this rule and so every query would invoke a dynamic test for whether there was a subProperty of the property being queried for. | | | Future work on adapting the rule engines to exploit the capabilities of the more sophisticated database backends will be considered. |

| | Rule Engine API (JSR-94), What Next? |
| | Obviously, implementing a rule engine is a bit harder than understanding the high level concept. | | | In order for the rule engine to reach a valid set of results, the facts must be evaluated as a closed system. | | | Rete defines how rules should be converted into nodes to form a network, which optimizes how objects are evaluated. |

| | In addition, a rule evaluation may result in more than simple yes/no answers and contain additional information that would be required by an application to now perform the requested access to the resource. | | | This rule may be composed of one or more conditions that might only be evaluated with application context specific data. | | | An entitlement is the result of the execution of a formula, or rule that specifies what must be considered when deciding whether a given user has rights to manipulate or use a given resource (or object). |

| | The ability to configure the rule engine to use different algorithms for evaluation. | | | This is evaluated at run-time by the rule engine rather than at compile time. | | | In my opinion one of the major goals of the next specification should be to define a forward-chaining or inferencing rule engine profile and describe the behavior of this "Java Virtual Rule Engine". |

| | Does Your Project Need a Rule Engine @ JAVA DEVELOPER'S JOURNAL |
| | Rule engines offer a framework for isolating the business logic in your applications; this framework is simpler and more flexible than look-up tables. | | | A rule engine is also easier to use and integrate than a database table. | | | The only stipulation is that the rules we write in the rule engine match the properties in the parameter class. |

It is used in connection with 'CommonRules' from IBM, and was developed in connection with IBM's Business Rules for E-Commerce Project. | | | Motivated by the importance of the content language aspect of agent communication, we focus in particular on business rules as a form of content that is important in e-commerce applications such as bidding negotiations. |

| | Jess Inventor Opines About Rule Engines and Java |
| | Jess is all about integration with other systems: it's easy to embed, it's easy to extend, it's easy to call out to Java from the rule language, and licensed users get the source code, so you can modify anything in the engine if you want. | | | My early projects concerned applying heuristic methods to problems in drug design, which led to a project applying heuristic rules to natural language understanding—which is the project for which Jess was originally created. | | | Ernest J. Friedman-Hill, developer of the Java Expert System Shell (Jess), discusses the history and future of his rule engine and speaks out about the application of artificial intelligence and expert systems in real-world Java development. |
