The third in a series of five articles illustrates the need for a better understanding of the indexing function. (AB)

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.

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)

SOME MACHINE-PRODUCED INDEXES ARE COMPARED TO ASSIST IN DECIDING ON THE FORMAT FOR A PROPOSED INDEX. THE OBJECTIVES OF AN INDEX AND THE SEARCH PROCEDURE ARE ANALYZED, AND AN EXPLANATION AND A RELATIONSHIP IS GIVEN FOR KEY-WORDS-IN-TITLE AND KEY-REFERENCES OF THE SAME ARTICLE. BASED ON THE COMPARISON OF THE INDEXES, A 53- YEAR CUMULATIVE INDEX WAS…

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)

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)

Summarizes findings from a survey administered to identify indexer opinion of the PRECIS indexing language, notes advantages and disadvantages, and discusses PRECIS's impact on the British library community. (SW)

This paper was prepared to provide a frame of reference to the role of microfilm within the information retrieval world and to provide an opportunity for evaluation of the use of microforms for active retrieval applications. The paper discusses the principles of information retrieval, considers subject and classification indexing, and describes…

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 -…

The KWAC Index Generation Program was implemented at the State University of New York at Buffalo. It consists of only 252 statements for the COBOL Compiler Edition V310222 on the CDC6400 computer under the KRONOS operating system in the batch mode. The KWAC program is essentially a KWIC index generator designed for a special purpose for use in a…

Problems in indexing library and information science literature occur because of the speed of introduction of new terms, the nature of class headings, and the uncertain terminology of the field. Vocabulary control requires control over the concepts selected (the depth of indexing), the form of expression of concepts and the syndetic apparatus of…

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…
