Expert Systems in Libraries

Abstract

Expert systems differ from other computer programs in that they: use problem solving using uncertain or judgemental knowledge; give explanations of the reasoning process; and have the ability to absorb and utilise new information to improve the problem solving capabilities. The development of library expert systems lag behind other applications, but the number of library-oriented functions which are candidates are quite large and include: information retrieval; selection of codes and subject headings during cataloguing; the development and implementation of specialised classification schemes and thesauri; front ends for on-line systems; and decision support systems.
