Bloomfield, Masse – Special Libraries, 1971
The last in a series of five papers, the author concludes that only three characteristics of indexing seem to be capable of being compared quantitatively. These are breadth of vocabulary, depth of indexing, and the use of see and see also references. (AB)

Stevens, Mary Elizabeth – 1970
A survey of automatic indexing systems and experiments has been conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including…

Landgraf, Alan L.; And Others – Journal of Library Automation, 1973
An experiment was conducted to design a corporate author index to a large bibliographic file. The nature of corporate entries necessitates a different search key construction from that of personal names or titles. Derivation of a search key to select distinct corporate entry records is discussed. (7 references) (Author)

Humbert, Karen – Drexel Library Quarterly, 1972
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)

Anderson, James D. – Journal of the American Society for Information Science, 1994
Discusses standards as tools to promote compatibility and improve practice, the role of research versus expert opinion in creating standards, and the changing scope of indexing standards. The current draft of the NISO (National Information Standards Organization) American Standard Guidelines for Indexes in Information Retrieval (Z39.4) is…

Lay, William Michael – 1973
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…

Petrarca, Anthony E.; And Others – Journal of Chemical Documentation, 1971
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. (17 references) (Author/NH)

Burnett, John E.; And Others – Journal of Documentation, 1979
Analyzes a study of the effect of controlled variations in indexing vocabulary size on retrieval performance, using the Cranfield 200 and 1400 test collections. Sets of variable-length character strings were tested, in an application of the Cluster Hypothesis and in a series of linear associative retrieval experiments. (Author/SW)

Conaway, Charles W. – 1973
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…

Diodato, Virgil; Gandt, Gretchen – Journal of the American Society for Information Science, 1991
Describes a study that examined back of book indexes produced by 37 authors and 27 nonauthors to see whether differences between the 2 groups of indexers could be discerned by counting the occurrence of 3 characteristics in their indexes: number of index pages, modified headings, and cross-reference use. (27 references) (LRW)

Standera, Oldrich – 1971
The Text-Pac System is capable of generating indexes and bulletins to provide a current information service without the selectivity feature. Indexes of the accumulated data base may also be used as a basis for manual retrospective searching. The manual search involves searching computer-prepared indexes from a machine readable data base produced…

Fidel, Raya; Efthimiadis, Efthimis N. – Information Processing & Management, 1995
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…
