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.

The application of computer techniques to the making of concordances and indexes has brought about many innovations including the KWIC format and the exhaustive concordance. Although claims for the merits of these concordances are not always justified, the KWIC method offers the following advantages: (1) the detection of formulaic expressions and…

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 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…

This programmed course consists of four lessons which cover the general principles of indexing, the specific methods of coordinate indexing, and the use of the Educational Resources Information Center (ERIC) Thesaurus. In the first volume the five appendices contain: (1) an index to the major themes of the course, (2) some definitions of form…

This volume contains the first two lessons of a course in subject indexing based upon the Educational Resources Information Center (ERIC) Thesaurus, Lesson 1 is an introduction to indexing, containing definitions and concepts related to the theory of indexing and information retrieval as well as an introduction to the ERIC Thesaurus. Lesson 2 is…

The author discusses information retrieval systems with particular emphasis on the assignment of descriptor terms. She first explains the method of determining terms by deriving key words from a title or abstract, a procedure that can often be carried out by a computer. After discussing the problems of derived indexing, the author explains the…

Computerization seems to offer some solutions to the inadequacies of the card catalog. However, vocabulary obstacles must be overcome before the history, art history, and art students alike can enter libraries all over the world and quickly satisfy their various needs. (10 references) (Author/NH)

A brief description of an efficient information retrieval system by which students, teachers, researchers, etc., may store information and data that are pertinent to their work. (AK)

The third of four volumes in a series describing the basic documentation practices involved in the initial setting up and subsequent operation of an information-library organization to provide defense-aerospace scientific and technical information services, this manual consists of three sections. "Information Retrieval," by Tom Norton,…

The International Bureau of Education's (IBE) thesaurus lists descriptors for retrieving information in the field of education from computerized data banks. The largest section is an alphabetical array of descriptors and identifiers, with French equivalents. These are cross-referenced with "use" and "use for" terms as well as…

The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…

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…
