Jess (Java Expert System Shell)

Jess (Java Expert System Shell) is a software tool that lets programmers create expert systems—programs that simulate human decision-making in specific domains, like medical diagnosis or financial advice. Built using Java, Jess allows users to define rules and facts, enabling the program to infer conclusions based on the information provided. Essentially, it helps computers think logically and make decisions similar to how a human expert would, using a flexible and powerful framework. This makes it useful for applications that require specialized knowledge and reasoning capabilities.
