As part of the report on the California State Library Processing Center (CSL-PC) design and specifications, this volume covers: (1) file maintenance, a discussion of updating system files with new entries and MARC tapes; (2) authority verification, the correction and standardization of subject headings and author names; (3) the filing system for a…

Examines through a series of mathematical models (theorems, descriptions, and examples), properties and operations on inverted files, which are used in an information retrieval system based on thesaurus with weighted descriptors. (CWM)

Based on the principle that alphabetical arrangement should be based on the characters actually appearing in the sort field, a computer filing code was produced which provides rules for formatting entries for computer manipulation. This study applies the principles developed in that code to library subject headings, using a sample of the Library…

Analyzes the use of weights to denote a query representation and/or the indexing of a document as a generalization of a Boolean retrieval system. Criteria are given for the functions used to evaluate the relevance of the records to a specific query and a new evaluation approach is suggested. (CWM)

Presents a new method of document retrieval based on the fundamental operations of fuzzy set theory. Basic notions are introduced. Then the syntax and semantics of the proposed language for document retrieval is given, and an algorithm allocating documents to particular queries is described and its properties are discussed.

This manual describes information processing procedures for Museum Computer Network (MCN) systems. The first section contains general rules for preparation of input: conventions for all data; conventions for controlling the appearance of output; conventions for automatic sorting of data; conventions for user specified sorting of data; and…

A description of a retrospective document retrieval system is given in which equifrequent fragments are used as language elements for compression coding and retrieval. The critical parameters governing the system are identified, and restrictions imposed by the parameters on the selection of fragments are outlined. Changes necessary in the…

This guide identifies and describes the subject areas covered by the ERIC Clearinghouses. Each Clearinghouse scope statement is provided in the following three-part format: (1) Formal Statement--A comprehensive and detailed description of the scope areas, mainly for use by the ERIC Facility in assigning documents (on the basis of their subject…

The thesaurus is divided into two parts. The first part lists descriptor terms under eight main areas of concern in foreign language instruction; the second lists terms alphabetically and includes "use" and "use for" notations. More that 500 descriptors are included. An introduction describes the work of the Information Center for Research in…

The introductory section of the paper expresses its purpose: to devise a classification scheme for career education resource material, which will be used to develop the USOE Office of Career Education Resource Library and will be disseminated to interested State departments of education and local school districts to assist them in classifying…
