Semantic Tools in Information Retrieval.
Rubinoff, Morris; Stone, Don C.
This report discusses the problem of the meansings of words used in information retrieval systems, and shows 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) are investigated in some detail. Finally, experiments now in progress are described which involve 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.
