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…

A series of four experiments was performed based on a model of human information processing. The model postulates four stages in the processing of an external stimulus: encoding (stage 1), central processing (stage 2), response selection, e.e. decoding (stage 3), and response execution (stage 4). The total reaction time can be decomposed into two…

Three major presentations from the 1973 Library Automation Research and Consulting Institute are included here. The first outlines the course of library automation in the preceding 10 years. The second is a discussion of the Los Angeles Unified School District's Automated Instructional Materials Handling System (AIMS), which includes materials…

The history, purpose, and operation of six computer-based information networks are described in general and nontechnical terms. In the introduction the many definitions of an information network are explored. Ohio College Library Center's network (OCLC) is the first example. OCLC began in 1963, and since early 1973 has been extending its services…

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. ERIC operates at four levels. At the top is the governmental level office, central ERIC, which supervises the ERIC Processing and Reference…

It is necessary to distinguish the functions, services and products of various types of information services. For example, document centers, clearinghouses, referral centers, and special libraries deal mainly with information in a broad sense. The main function of information analysis centers, however, is to optimize the ratio of knowledge to…

This paper on Thesauri in Educational Documentation attempts to show by description and analysis the difference in application between thesauri and classification schemes as indexing languages in documentary information systems, and from this to infer possible future developments. First, the differences between the pre-coordination and…

This preliminary report of research conducted at the Linguistics Documentation Centre of the University of Ottawa describes a bilingual experiment into the elaboration of well structured formulary routines for making the writing of abstracts easier, and at the same time standardizing and generally augmenting the information given in them. The…

A selected set of terms and definitions relating to computer networking is presented in a coherent manner. An introduction gives the rationale for the glossary, defines the scope by a brief tutorial overview, and states the glossary format and conventions. The glossary is arranged alphabetically and contains about 140 definitions and associated…

The document contains the three Summary of Activities Reports (1970 through 1973) that the American Society for Information Science submitted to the Office of Education and the National Institute of Education. The performance categories for each report include: 1) document processing; 2) information analysis; 3) services; 4) promotional…

This study focuses on the production, dissemination, and assimilation of material published in the major journals on geography. The "core" journals selected for the study were: "Economic Geography,""Geographical Review,""Annals of AAG" and "Professional Geographer." The tangential journal included…

The development of automatic indexing, abstracting, and extracting systems is investigated. Part I describes the development of tools for making syntactic and semantic distinctions of potential use in automatic indexing and extracting. One of these tools is a program for syntactic analysis (i.e., parsing) of English, the other is a dictionary of…

Decisionmaking is the process of choosing among alternatives, or turning inputs into outputs. In a situation of information overload, inputs exceed the decisionmaker's capacity to assimilate and act on the information as well as his ability to evaluate every alternative. Decisionmakers have a variety of responses to information overload, some of…

The three documents contained in this report describe an interactive retrieval language implemented for the IBM 360/67 of the Campus Faculty at Stanford University, between October 1969 and May 1970. The three reports are: (1) DIRAC--An Interactive Retrieval Language with Computational Interface, (2) DIRAC--An Overview of an Interactive Retrieval…
