This review of the Keyword-in-Context (KWIC) indexing considers its inception by Luhn, its original format and purpose, various applications and uses of the basic KWIC concept, its advantages and disadvantages, and evaluations of its effectiveness. (30 references) (Author/NH)

The development of an automatic indexing technique, called Double KWIC (DKWIC) Coordinate Indexing, is described which extends the KWIC indexing principles to provide easy access to an additional level of specificity for information indexed under these frequently appearing terms. Chapter 2 discusses indexing terminology and some fundamental…

It is shown that this new automatic indexing technique can be applied with the same effectiveness shown earlier for indexes derived from words in titles or title-like phrases; the basic difference being that linear notation symbols rather than words are used as the indexing units.

Variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases. (Author)

The operational retrospective retrieval service offered by BIOSIS exploits a file created essentially without vocabulary control. A pragmatic program of file building criteria has been persued which has provided improved retrieval and an annual summary of the vocabulary of the literature. (11 references) (Author/KE)

A procedure for producing a Key-Word-Out-of-Context (KWOC) alerting tool for a specific field of information as a temporary alternative to computerization. (Author/AB)

The indexing of Cranfield I and II is given and critical comments made of this indexing. Comparisons of Cranfield indexing to other types of indexing are made. (AB)

Creation of a quarterly keyword index to campus grant projects is the chief investigator's name as the key to a section of project summaries. A third section is also included, listing the summaries under the name of the sponsoring department. (Author)

Results obtained by processing a corpus of 2675 medical titles indicate that several properties definable in terms of inclusion relationships among terms have significance for vocabulary control. (Author)

Describes the origin of the Thesaurus of ERIC Descriptors and how additions are made to his volume. (DE)

An access method for bibliographic records that combines features of the search key approach and the inverted file approach. Permits extension of search key technique to large files. (Author/LS)

Compares the retrieval performance of a technique for machine-aided indexing using a controlled vocabulary with that of a Key Word Out of Context Index, basing conclusions on the results of 20 subject searches of a database containing summaries of defense management data. (FM)

The retrieval effectiveness of Keywork-In-Context (KWIC) indexing is sought using a simple search simulation which constrains the user to approach a KWIC index with subject keywords and references dictated by a conventional index. A comparison of several KWIC index studies, using various methodologies, shows retrievability ratios of 35 percent -…

A library survey to examine and analyze locally generated title derivative keyword indexing in academic and public libraries and its findings are presented. The project was organized in two phases. The first attempted to identify successful title derivative indexing programs through a literature review, correspondence with individuals known to be…

Subjects covered in this bibliography include manual, mechanized and automated techniques, evaluation of systems, standards, storage and retrieval systems, research, vocabularies, author participation, permuted title indexing, citation indexing, and specialized indexing requirements, i.e. chemistry, medicine, patents, engineering drawing, and…
