A statistical method of drawing index terms or "highlights" from text is presented that uses no stop list, stem or other language- and domain-specific components, allowing operation in any domain or language with minimal modification. Some experimental results are presented, showing operation in six different languages. (67 references)…

Examines the knowledge base of an intermediary expert system that provides advice about search term selection. Topics include a proposal for an integrated approach, including an option focusing on terminological attributes based on knowledge acquired from professional searchers; and the content of the knowledge base and the research needed to…

This research reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used include term filtering, automatic indexing, and cluster analysis. The Worm Community System, used by molecular biologists studying the nematode worm C. elegans, was used as the testbed for this research.…

An experiment in superficial indexing was carried out to elaborate the contract between indexing with a controlled vocabulary and using automated methods as described by Salton. (Author)

Discussion of electronic image processing focuses on the need for indexing to ensure adequate retrieval. Highlights include icons, i.e., reduced pictorial surrogates; file staging; indexing languages, including examples of thesauri; and pictorial languages, including a HyperCard system. (Contains eight references.) (LRW)

The four chapters included in this report are based on LINCS project activities undertaken since 1968, with an emphasis on indexing tools in the language sciences and related problems. Chapter one, "Indexing Tools for the Language Sciences: Methodology," discusses the development of a LINCS thesaurus and its role in the LINCS network.…

A THESAURUS OF EDUCATIONAL TERMS WAS PRODUCED TO PROVIDE A TERMINOLOGY BASE WHICH WOULD BE AMENABLE TO RAPID AND EASY MODIFICATION AND UPDATING. 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…

THE AVAILABILITY OF STUDENTS AT THE UNIVERSITY OF DAYTON HAD SUGGESTED THEIR POSSIBLE USE AS INDEXERS FOR INDEXING DOCUMENTS FOR THE AEROSPACE MATERIALS INFORMATION CENTER (AMIC). A STUDENT HAD BEEN EMPLOYED TWO YEARS AGO AND INFORMALLY TRAINED IN INDEXING. THE SUCCESS OF THAT EXPERIENCE, THE SUCCESSFUL DEVELOPMENT OF A CONTROLLED VOCABULARY, AND…

GUIDELINES AND CONVENTIONS ARE PRESENTED FOR THE SELECTION OF APPROPRIATE TECHNICAL SUBJECT INDEXING AND RETRIEVAL TERMINOLOGY AND THE DISPLAY OF THIS TERMINOLOGY IN A THESAURUS FORMAT. THESE CONVENTIONS WERE DEVELOPED BY PROJECT LEX, THE DOD TECHNICAL THESAURUS TASK FORCE, IN COOPERATION WITH THE ENGINEERS JOINT COUNCIL. A DISCUSSION IS GIVEN OF…

Presents the human evaluation of ILIAD, a program for machine-aided indexing that was designed to assist expert librarians in computer-aided indexing and document analysis. Topics include controlled indexing and free indexing; natural language and concept-based information retrieval; evaluation methodology; syntactic variations; and a comparison…

This brief review of the Educational Resources Information Center (ERIC) system is intended to make users more aware of (1) the system as a whole, (2) the process of indexing educational literature for the database, and (3) the role of the Thesaurus of ERIC Descriptors in the overall information dissemination process. An overview of the ERIC…

THE REPORT DESCRIBES THE EFFECTS THAT A CONTROLLED VOCABULARY HAS ON THE INDEXING AND SEARCHING OPERATIONS OF THE DOCUMENT RETRIEVAL SYSTEM ESTABLISHED BY THE UNIVERSITY OF DAYTON FOR THE AIR FORCE MATERIALS LABORATORY. THE SYSTEM CONTAINS ABOUT 30,000 SCIENTIFIC AND TECHNICAL REPORTS COVERING ALL ASPECTS OF MATERIALS RESEARCH AND IS CONTROLLED BY…

This study examines automatic indexing performed with a manually constructed thesaurus on a document collection of titles and abstracts of library science master's papers. Errors are identified when the meaning of a posted descriptor, as identified by context in the thesaurus, does not match that of the passage of text which occasioned the…

An experiment is reported in which 78 subjects examined synonymic and generic-specific relationships among 513 terms compiled from subject indexes of programming textbooks and manuals. Terms were assigned in groups of 20 so that given decisions for terms could be compared for three subjects. The experiment suggested such methodological…
