Introduction: This paper presents a qualitative exploration of university students' experience of searching an online public access catalogue. The study investigated how students conceptualise their searching process, as well as how students understand themselves as seekers of information. Method: Following a search task, thirty-eight…

Reports the results of experiments using colon classification for the analysis, representation, and retrieval of primary information from the full text of documents. Recall, precision, and search length measures indicate colon classification did not perform significantly better than Boolean or simple word occurrence systems. Thirteen references…

Describes the design of a classification scheme for reusable software and the implementation of an information retrieval system for reusable software using the SMART system. Highlights include a review of other systems for reusable software; system design; reorganization of software documentation; and system testing, including recall and…

Summarizes studies of pseudoclassification, a process of utilizing user relevance assessments of certain documents with respect to certain queries to build term classes designed to retrieve relevant documents. Conclusions are reached concerning the effectiveness and feasibility of constructing term classifications based on human relevance…

Six uses of classification in online retrieval systems are envisioned--to improve recall and precision; to conceptualize meaning of vague search terms; to provide structure for browsing; to provide framework for retrieval of nonbibliographic information; to collocate citations; and to achieve compatibility of retrieval languages. Seven sources are…

Part One, Automatic Content Analysis contains: "Content Analysis in Information Retrieval;""The 'Generality' Effect and the Retrieval Evaluation for Large Collections;""Automatic Indexing Using Bibliographic Citations" and "Automatic Resolution of Ambiguities from Natural Language Text." Part Two, Automatic…

This book deals with properties of vocabularies for indexing and searching document collections; the construction, organization, display, and maintenance of these vocabularies; and the vocabulary as a factor affecting the performance of retrieval systems. Most of the text is concerned with vocabularies for post-coordinate retrieval systems, with…

Description of classification schemes for fiction book retrieval covers traditional methods, universal systems, special systems, genre systems, and development of the AMP-classification system based on multidimensional analysis of users' requests (subject matter, setting, author's intention, accessibility). Trial applications and retrieval tests,…

Argues that classification schemes like LC and Dewey Decimal are not adequate devices for organizing and retrieving library materials, and suggests the use of two separate schemes, one for shelf arrangement of materials and the other to provide subject searching capability on automated systems, as a solution to the problem.

A meeting was held to explore critical issues and problems related to subject access to online bibliographic records of monographic literature. The 23 researchers, practitioners, and policymakers who attended represented national and research libraries, bibliographic utilities, database vendors, library schools, indexing and abstracting services,…

This examination of abstracting-indexing services for the field of history focuses on Historical Abstracts (HA) and America--History and Life (AHL), and their relationship to the American Bibliographical Center's Subject Profile Index (ABC-SPIndex). The history, scope, selection criteria, and classification arrangements of the two databases are…

The report is concerned with the implementation of an on-line information storage and retrieval system for the Rome Air Development Center. This system is to incorporate techniques of automatic document classification for a large document collection in an interactive environment. Following a review of the system design, the implementation of the…

The paper reports on a series of programs that have been developed at the Moore School to process data-bases, consisting of textual items, and to index and arrange the data items in accordance with an automatically generated classification system. The programs produce the directories and the rearranged data-base on microfilm, where it may be…

Emphasizes class maintenance of National Library of Medicine's bibliographic retrieval file in which maintenance actions (replacement, deletion, addition) reflect yearly changes in Medical Subject Headings (MeSH). File maintenance of other authoritative information attached to headings, class maintenance failures, checking class maintenance,…

Two papers are included as Part Four of this report on Salton's Magical Automatic Retriever of Texts (SMART) project report. The first paper: "A Controlled Single Pass Classification Algorithm with Application to Multilevel Clustering" by D. B. Johnson and J. M. Laferente presents a single pass clustering method which compares favorably…
