The inverted index is the main data structure used by all the major search engines. Search engines build an inverted index on their collection to speed up query processing. As the size of the web grows, the length of the inverted list structures, which can easily grow to hundreds of MBs or even GBs for common terms (roughly linear in the size of…

We examined the post-publication period of six feminist articles (Hart, 2006) using citation indexing. From our findings, we argue that both indexes are embedded within an enduring system of academic patriarchy and neither index truly measures impact of scholarly work. Implications of current impact measures for promotion, tenure, and merit are…

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…

Some of the literature concerning citation indexing is discussed with emphasis on research projects. (52 references) (Author/NH)

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)

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 -…

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…
