SEMANTIC TOOLS IN INFORMATION RETRIEVAL,
Abstract
The report discussed the problem of the meanings of words used in information retrieval systems, and showed how semantic tools can aid in the 'communication' which takes place between indexers and searchers via index terms. After treating the differing use of semantic tools in different types of systems, two tools (classification tables and semantic expansions) were investigated in some detail. Experiments were described concerning statistical techniques for semi-automatic generation of a vocabulary and a set of classification tables for an area of specialization. These techniques enable the construction or updating of semantic aids with far less intellectual effort than now required, but still retain a consensus of expert opinion through the literature produced by experts.
