Abstract
Optimal retrieval in on-line searching can be achieved through combined use of both natural language and controlled vocabularies. However, there is a large variety of types of controlled vocabulary in data bases and often more than one in a single data base. Optimal use of these vocabularies requires understanding what types of languages are involved, and taking advantage of the particular mix of vocabularies in a given data base. Examples 4 major types of indexing and classification used in data bases and puts these 4 in the context of 3 other approaches to subject access. Discusses how to evaluate a new data base for various forms of subject access.
