A thesaurus for improving information retrieval in an integrated legal expert system

This paper presents a critical analysis of a legal expert system architecture, focusing the knowledge representation that represents the most important step in the construction of a modern legal information system. After a long period of experience, we can speak of global systems, because the formalized system knowledge is only a part of system data that may be improved to the user also from a periferic data bases. The new legal systems are tools that can offer information for decision aid and user consulting from different modules and also they offer a sophisticated information retrieval founded, for instance, upon hypertext models or thesauri.
