Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document. (VT)

An information retrieval system was developed using technical word occurrences as a basis for classification. A set of words, designated a vocabulary, was selected from the middle range of frequency listing of words occurring in an experimental sample of 94 documents. The selection produced 115 non-function words with technical definition that did…

The purpose of the study was to determine how many questions judged relevant to an article are also judged relevant using different length representations of the article, and how this proportion changes as the length of the representation changes. Several persons made relevance judgments for each of a set of articles to each of a set of questions.…

Minimum, maximum, and average lengths and frequency counts for the data elements in the Chemical Substance and General Subject segments of the Standard Distribution Format (SDF) files distributed by Chemical Abstracts Service are presented. (5 references) (Authors)

QUEST is an interactive conversational Programming System (CPS) that was developed to serve as a conversational interface between a searcher of the Educational Resources Information Center (ERIC) files and the North Carolina Science and Technology Research Center's Inverted File Search Program (STRC-IVS). This paper describes QUEST: its costs,…

Reports preliminary results of a study to develop and automate new metrics for assessment of information quality in text documents, particularly in news. Through focus group studies, quality judgment experiments, and textual feature extraction and analysis, nine quality aspects were generated and applied in human assessments. Experiments were…

Addresses the query- versus document-oriented dichotomy in information retrieval. Introduces a maximum likelihood approach to utilizing feedback data that can be used to construct a concrete object function that estimates both document and query parameters in accordance with all available feedback data. (AEF)

Provides an overview of current image retrieval systems. Describes the architecture of the SOFM (Self Organizing Feature Maps) based image retrieval system, discussing the system architecture and features. Introduces the Kohonen model, and describes the implementation details of SOFM computation and its learning algorithm. Presents a test example…

The article describes the Educational Resources Information Center (ERIC), an information retrieval system, and the Northern Illinois University Clearinghouse in Career Education (CICE), a part of the ERIC system that prepares information on industrial arts, and on adult, vocational and technical, and career education.

The periodic TRECs (Text Retrieval Conferences) have reported the results of a variety of recall studies in large-scale document retrieval. While the efforts of TREC are noteworthy and laudable, there are reasons why its results, especially the recall values that are central to its conclusions, should be accepted with some caution. (Contains 17…

Presents criteria for an effective syntagmatic relator system and describes how conceptual syntagmatic relationships are expressed in natural language, commenting on the adequacy of such expressions for document retrieval systems. Only one type of expression, a gestalt structure, represented as a frame, conforms to the criteria. (Author/JKP)

Describes preliminary investigation of the use of International Computers Limited's Distributed Array Processor (DAP) for parallel searching of large serial files of documents. DAP hardware and software, test collections, measurement of DAP performance, search algorithms, experimental results, and DAP suitability for interactive searching are…

The application description is directed to those desiring to acquaint themselves with the characteristics of the General Information Processing System (GIPSY). It provides guidelines and aids for the preparation and use of the system, and covers such areas as: (1) Information Collection and Creation, (2) Information Retrieval, (3) Maintenance…

Situationally relevant items of information are those that answer, or logically help to answer, questions of concern. Significant situationally relevant information is explained in terms of changes of view in relation to questions of concern. It is claimed that situational relevance is an explication of the ordinary notion of practical relevance.…
