- Abstract
- The purpose of this selected bibliography is to introduce issues and problems in relation to thesaurus construction and to present a set of readings that may be used in practical thesaurus design. The concept of thesaurus is discussed, the purpose of the thesaurus and how the concept has evolved over the years according to new IR technologies. Different approaches to thesaurus construction are introduced, and readings dealing with specific problems and developments in the collection, formation and organisation of thesaurus concepts and terms are presented. Primarily manual construction methods are discussed, but the bibliography also refers to research about techniques for automatic thesaurus construction.
