Abstract

This paper proposes the integration of three paradigms of computerisation of legal information: expert systems (inferencing), hypertext, and text retrieval. It explores the relationships between them, and why they are complementary, particularly in relation to the knowledge representation required by each paradigm. It proposes the development of 'integrated' computerisation of legal information. It explains how the DataLex Legal Workstation software, which combines software to create expert systems (YSH), hypertext (HYPE), and free text retrieval (AIRS) into one general-purpose tool, implements the theoretical approach advanced. The 'Privacy Workstation' application is used to illustrate the arguments put forward in the paper. The inference engine component, YSH, supports backward chaining, forward chaining and procedural inferencing and uses a quasi-natural language based rule representation. Six types of integration between the three components are explained. Use of a workstation is conceptualised as 'enquiries across three dimensions' of legal knowledge representation, and the resulting system is described as an 'open-ended expert system'. (This was the first paper explaining the DataLex Workstation software and approach.)

Keywords: DataLex, expert systems, artificial intelligence, legal reasoning, inferencing, hypertext, text retrieval, search engines
