Abstract:

The report describes the basic components of an information system, those operations necessary for the storage, organization, and access to documents and the information contained within the documents. Concentration has been aimed primarily at the access process, which seems to be of greatest concern to CERL. The types of access which have been identified include indexing by subject heading, indexing by keywords-in-context, coordinate indexing, and the issue-based approach. Hierarchical classification, also of concern to CERL, has been identified as part of the organizational process, although its role in access is discussed briefly. Syntactic analysis is discussed as it applies to the other indexing systems, primarily as a modification of the keyword-in-context index, the automated subject heading index, and indirectly as the role function in the coordinate index. The relational sentence concept, a preliminary approach proposed by CERL, is also reviewed and discussed.
