The objective of this project is to help searchers convert queries
in their own language into the terms used in unfamiliar indexes and classifications
A dictionary ("entry vocabulary") leads from words or phrases familiar
to the searcher to the associated terms in the index or classification
to be searched. The scope ("domain") covered by large bibliographic or
textual databases usually includes several specialized topical areas ("subdomains").
Each topical area reflects the work of community of specialists. These
communities evolve their own specialized vocabulary: different terms and
specialized meanings of other terms. The obvious approach is to create
a single dictionary for the target database as a whole. But searches are
usually concerned with a specialized topic within a database. This raises
the following questions:
- Should search support should be customized to each subdomain?
- Would that lead to a better (more specialized) search terms?
- Would that lead to different, better search results?
Specialized dictionaries (entry vocabulary modules) have been created
for specialized topics (subdomains) in order to find out
Preliminary analyses indicate substantial differences
in the choice of metadata terms and in the retrieval results.
