Advanced conceptual network usage in library database queries
J.J.A.C. Hoppenbrouwers · 1998
This paper describes the generic principles of Decomate-II's Concept Browser. It discusses the three main problems in using a thesaurus or conceptual network to help users formulate database queries: the network maintenance problem, the network navigation problem, and the network-to-database mapping problem. Possible solutions to all these problems are proposed, based on previous experiences with concept network systems. Care is taken to keep the resulting system suitable for production use in an existing library environment based on Boolean keyword retrieval from a large collection with uncontrolled vocabulary. Keywords: Semantic network, thesaurus, conceptual network, knowledge navigation, lexicon, conceptual modeling, topic browsing, document retrieval, Decomate-II.
