Abstract: After a period of experiment and evolution in the 1950s and 1960s, a fairly standard format for thesauri was established with the publication of the influential Thesaurus of Engineering and Scientific Terms (TEST) in 1967. This and other early thesauri relied primarily an the presentation of terms in alphabetical order. The value of a classified presentation was subsequently realised, and in particular the technique of facet analysis has profoundly influenced thesaurus evolution. Thesaurofacet and the Art & Architecture Thesaurus have acted as models for two distinct breeds of thesaurus using faceted displays of terms. As of the 1990s, the expansion of end-user access to vast networked resources is imposing further requirements an the style and structure of controlled vocabularies. The international standards for thesauri, first conceived in a print-based era, are badly in need of updating. Work is in hand in the UK and the USA to revise and develop standards in support of electronic thesauri.

Abstract

At the time when the Institute of Information Scientists was launched, well established principles of classification, especially faceted classification, provided an excellent springboard for developments in knowledge organization thereafter. The principles of thesaurus construction and use were worked out during the first two decades of the Institute's existence. Up until the end of the 1980s, most practical systems to exploit any of these vocabularies were held on cards, some of them highly ingenious. The subsequent arrival of the desktop computer, soon followed by the growth of networks providing access to an almost unimaginable quantity and variety of resources, has stimulated evolution of the knowledge organization schemes to exploit the technology available. Anecdotes of events and practical applications of controlled vocabularies illustrate this account of developments over the period.

Abstract

The information retrieval thesaurus emerged in the 1950s, settled down to a more-or-less standard format in the 1970s and has continued to evolve marginally since then. Throughout its whole lifetime, doubts have been expressed about its efficacy with emphasis latterly on cost-effectiveness. Prolonged testing of different styles of index language in the 1970s failed to settle the doubts. The arena occupied by the debate has moved from small isolated databases in the post-war era to diverse situations nowadays with the whole Internet at one extreme and small in-house collections at the other. Sophisticated statistical techniques now dominate the retrieval landscape on the Internet but leave opportunities for the thesaurus and other knowledge organization techniques in niches such as image libraries and corporate intranets. The promise of an ontology-driven semantic web with linked data resources opens another opportunity. Thus much scope remains for research to establish the usefulness of the thesaurus in these places and to inspire its continuing evolution.
