MLISP (meta-LISP) is a high level list-processing and symbol-manipulation language based on the programing language LISP (List Processor). MLISP programs are translated into LISP programs and then executed or compiled. MLISP exists for two purposes: (1) to facilitate the writing and understanding of LISP programs; (2) to remedy certain important…

This document is a study of the processing of questions input to computerized question-answering system such as the RAND Relational Data File. The process consists of (1)transforming the natural-language question into a symbolic question (i.e., a certain formula of predicate calculus) and (2)generating the answer by calculating the value set of…

This unclassified-unlimited bibliography contains 183 references, with abstracts, dealing specifically with optical or graphic information processing. Citations are grouped under three headings: display devices and theory, character recognition, and pattern recognition.

The document retrieval system at Coordinated Science Laboratory is implemented on a Control Data 1604 computer system. Recorded information from each source article includes 1) conventional bibliographic data such as authorship, author affiliation, title, year of publication, etc., 2) detailed bibliographic data from each of the cited references,…

This report presents the principal objectives and results of the Context Information Processing Project and discusses the nature of context and its relationship to conventional models of information storage and retrieval. In this approach literature searching involves prediction, and context represents a new class of clues to be obtained and…

This report, resulting from the Context Information Processing Project, is a review of request language and search logic in its present state with the purpose of relating these findings to the design of QUERY (the language described in LI 001 652) and to context information processing needs. A basic assumption is that an information retrieval…

The purpose of this report is to summarize the content of a series of lectures given at the School of Library Science, State University of New York at Albany. Four summaries are presented. "The Limits of Information Retrieval" discusses the need for a theory of documentation and how it can be derived. "The Structure of Notification" considers in…

Sixth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form, this report deals with the query language, search strategy and related considerations for a particular information storage and retrieval system. One section of the…

A symposium with four major presentations centering on the topic of computer-based information retrieval. Also highlighted are several features of the Wisconsin Information System for Education (WISE-ONE) and the Educational Resources Information Center (ERIC) system. The first paper in the series discusses the development, current capabilities…

This document is a review of Canada's attempt to develop a standardized, multipurpose occupational classification system suited to national requirements. The main objective of Volume 1 the CCDO is to provide an instrument for use in manpower research and analysis, for statistical survey purposes, census taking, and for operational activities such…

Organizations which are currently providing computerized searches of the ERIC data base are listed and briefly described. For each of the over 120 sources of computer searches identifies in the document the following information is listed: name and complete address, population served, files available, how to submit an inquiry, form of search…

ERIC (Educational Resources Information Center) was the first attempt to develop a systematic way of collecting, storing, organizing, disseminating, and analysing information in the field of education.
