Artificial intelligence and law
Artificial Intelligence and Law (AI and Law) is a subfield of Artificial Intelligence (AI) mainly concerned with applications of AI to legal informatics problems and original research on those problems. It is also concerned to contribute in the other direction: to export tools and techniques developed in the context of legal problems to AI in general. For example, theories of legal decision making, especially models of argumentation, have contributed to knowledge representation and reasoning; models of social organization based on norms have contributed to multi-agent systems; reasoning with legal cases has contributed to case-based reasoning; and the need to store and retrieve large amounts of textual data has resulted in contributions to conceptual information retrieval and intelligent databases.
Although Loevinger, Allen and Mehl anticipated several of the ideas that would become important in AI and Law, the first serious proposal for applying AI techniques to law is usually taken to be Buchanan and Headrick. Early work from this period includes Thorne McCarty’s influential TAXMAN project in the USA and Ronald Stamper’s LEGOL project in the UK. The former concerned the modeling of the majority and minority arguments in a US Tax law case (Eisner v Macomber), while the latter attempted to provide a formal model of the rules and regulations that govern an organization. Landmarks in the early 1980s include Carole Hafner’s work on conceptual retrieval, Anne Gardner’s work on contract law, Rissland’s work on legal hypotheticals and the work at Imperial College, London on executable formalisations of legislation.
Early meetings of scholars included a one-off meeting at Swansea, the series of conferences organized by IDG in Florence and the workshops organised by Charles Walter at the University of Houston in 1984 and 1985. In 1987 a biennial conference, the International Conference on AI and Law (ICAIL), was instituted. This conference began to be seen as the main venue for publishing and the developing ideas within AI and Law, and it led to the foundation of the International Association for Artificial Intelligence and Law (IAAIL), to organize and convene subsequent ICAILs. This in turn led to the foundation of the Artificial Intelligence and Law Journal, first published in 1992. In Europe, the annual JURIX conferences (organised by the Jurix Foundation for Legal Knowledge Based Systems), began in 1988. Initially intended to bring together the Dutch-speaking (i.e. Dutch and Flemish) researchers, JURIX quickly developed into an international, primarily European, conference and since 2002 has regularly been held outside the Dutch speaking countries. Since 2007 the JURISIN workshops have been held in Japan under the auspices of the Japanese Society for Artificial Intelligence.
