Jess is a rule engine for the Java platform that allows developers to create and manipulate rules and facts within their applications. It provides a framework for building expert systems and enables the execution of complex decision-making processes by using forward-chaining inference based on the Rete algorithm.
About Jess
Jess was created in 1995 by Ernest Friedman-Hill at Sandia National Laboratories. It was developed to provide a Java-based rule engine that could be used for building expert systems and automating complex decision-making processes. Jess gained popularity for its efficient implementation of the Rete algorithm and its integration with Java applications.
Strengths of Jess included its efficient implementation of the Rete algorithm, strong integration with Java, and flexibility in building expert systems. Weaknesses involved a steep learning curve and less community support compared to newer technologies. Competitors included Drools, CLIPS, and IBM's ILOG JRules.
