Title: Zoeken in de bibliografische ruimte : de bijzondere rol van de hierarchische classificaties bij geautomatiseerde onderwerpsontsluiting
Source: Open. 25(1993) no.2, S.46-50
Year: 1993
Abstract: The universal classification schemes developed in the 19th century are a direct response to the social changes of that era. However, the increasing use of automation in libraries has highlighted the need fir greater precision in hierarchical structures. A thesaurus of used and related headings can be employed to show the spatial relationship of semantic terms. The resulting search profile can be further enhanced by the addition of citation weighting. To assist users to define searches more accurately libraries using large general classification schemes should consider adding supplementary classification data to records
