THE PRIMARY SOURCE OF TERMS WAS A SEMANTIC CODE DICTIONARY, PREVIOUSLY CREATED DURING THE INDEXING OF SOME 6,500 EDUCATIONAL RESEARCH DOCUMENTS. A FACETED STRUCTURE WAS CREATED. THE DISPLAY CONSISTED OF…

These two indexing systems are briefly described and experimental evidence is cited showing that a combination of both theories produces better retrieval performance than either one alone. Appropriate conclusions are reached concerning viable automatic indexing procedures usable in practice. (Author)

Summarizes the conclusions and recommendations of a survey of the coverage of documentation, library, and archives periodicals by six major abstracting and indexing services in 1973. (PF)

Discusses the connection between the fields of terminology and information science and demonstrates the importance of linguistics, in particular the theory of terminology, in the automation of such information processes as classification, indexing, and abstracting. Fourteen references are cited. (Author/EJS)
