Abstract

There is more to legal knowledge representation than knowledge-bases. It is valuable to look at legal knowledge representation and its implementation across the entire domain of 'computerization of law', rather than focusing on sub-domains such as 'legal expert systems'. The DataLex WorkStation software and applications developed using it are used to provide examples. Effective integration of inferencing, hypertext and text retrieval can overcome some of the limitations of these current paradigms of legal computerization which are apparent when they are used on a 'stand-alone' basis. Effective integration of inferencing systems is facilitated by use of a (quasi) natural language knowledge representation, and the benefits of isomorphism are enhanced. These advantages of integration apply to all forms of inferencing, including document generation and case-based inferencing. Some principles for development of integrated legal decision support systems are proposed.

Keywords: legal expert system, expert system, DataLex, knowledge base, integrated, natural language, hypertext, inferencing, artificial intelligence, document assembly
