This paper examines how the nature of the World Wide Web and characteristics of networked resources affect subject access and analyzes the requirements of effective indexing and retrieval tools. The current and potential uses of existing tools and possible courses of future development are explored in the context of recent research. The first…

Discusses the need to retrieve ideas in addition to content retrieval by such means as classification, subject headings, and keywords. Three models for idea retrieval are described, and a new model is proposed which combines selection, a controlled vocabulary, and logical structure. (seven references) (CLB)

Discussion of terms and how they are used in queries in information retrieval focuses on a transaction log analysis of queries posed on an Internet search service that isolated basic query structure syntactic patterns. Describes a linguistic model that classified Web queries and suggests implications for information retrieval system design.…

Proposes a model that assists in understanding indexing on the World Wide Web and presents an experiment assessing the validity of Inverse Document Frequency (IDF) as a term weighting strategy for Web documents. Findings indicate that IDF scores are not stable in the heterogeneous and dynamic context of the Web. (Author/AEF)

This second volume of the two-part project report describes the indexing system, developed by the research team and cooperating subject experts, designed to provide access to the literature in the field of educational sociology in a manner which will allow more flexible patterns of approach by the users of the system. The general system rationale…

Problems in indexing library and information science literature occur because of the speed of introduction of new terms, the nature of class headings, and the uncertain terminology of the field. Vocabulary control requires control over the concepts selected (the depth of indexing), the form of expression of concepts and the syndetic apparatus of…

Presents a taxonomy of 11 sources of information used during library and database searching based on observations of 49 searches in a variety of libraries and search situations. Three categories of sources are identified: those internal to the searcher, those created by the searcher, and those external to the searcher. (Contains 54 references.)…

Presents a model for teaching interdisciplinary research skills that can be applied to any two or more humanities or social science disciplines. Highlights include the definition and organization of the discipline, organization or printed reference tools, user definition of information needs, classification systems and subject headings, and online…

This document contains the three volumes of the technical report for development of the prototype of the Occupational Information Network (O*NET), which is intended to replace the "Dictionary of Occupational Titles.""General Introduction" (Norman G. Peterson) presents an overview of O*NET's purpose, content, and structure.…
