Iliad: a computer program for managing personal bibliographic knowledge bases.

ILIAD is a microcomputer based program that has been developed to facilitate the construction and management of bibliographic knowledge bases. The contents of these knowledge bases are selected bibliographic citations to the literature. The knowledge base contents are organized by knowledge models that permit access to and the retrieval of relevant information. A knowledge structure referred to as a 'relation' is the fundamental unit of this knowledge model. It is shown that conceptual networks of relations may be built and utilized to perform high quality, efficient information queries of the knowledge base. Quality and efficiency are assessed by the measures of recall and precision, functions of the general relevance of information retrieved, and time.
