Provides an overview of the Internet as it exists today, and a sampling of the kinds of information services it provides. (SR)

Introduces briefly some of the more common Internet information management tools, including Archie, Gopher, Veronica and Jughead, Wide Area Information Service (WAIS), and World-Wide Web. (SR)

Discusses government information on the Internet. Provides a broad list of collections of government information available on the Internet. (SR)

Tome Associates developed techniques to process natural language queries into search statements suitable for use in online text database systems. Problems discussed include word identification, handling of unknown words, system dictionaries, semantic categories and classification, truncation, stemming, disambiguation of multimeaning words, noun…

Introduces a special issue on research on hypertext systems and information retrieval. Systems design aspects, including navigation models, link weighting, multiple representation techniques, automatic authoring, user modelling, varying levels of abstraction, and evaluation techniques are addressed. (EA)

Proposes that document space and query space have different structures in information retrieval and discusses similarity measures, term independence, and linear structure. Examples are given using the retrieval functions of dot-product, the cosine measure, the coefficient of Jaccard, and the overlap function. (Contains 28 references.) (LRW)

Provides an overview of indexing in database management systems to provide librarians with more understanding of the possibilities and limitations of current information systems. Sequential, direct, indexed sequential, and virtual sequential file accessing methods are explained, and various binary tree structures are described. (EAM)

Explains componentware, a new paradigm in software development that is based on the concept of a software component, a self-contained unit of software which can be distributed over large networks. Discusses the need for new, Internet-based search and retrieval mechanisms, and the architectural requirements and mechanisms of componentware.…

Presents a domain-specific thesaurus for linguistic support of an information broker that employs an adaptive semantic-distance function based on pathfinder networks and algorithms for automated population by nominal compound interpretation and relational inheritance. Mathematical structure of thesauri and issues for further research are also…

Assesses the retrieval effectiveness of automatically constructed interdocument hypertext links in information retrieval (IR). Describes experiments using statistical and probabilistic techniques that were designed to obtain evidence concerning the usefulness of querying and browsing automatically constructed IR hypertexts. Results indicate a…

Presents a visualization tool for information retrieval that can display two different similarity measures, angle and distance, in the same space. Discusses the visual display of information-retrieval evaluation models and develops a new retrieval means based on the visual retrieval tool, the controlling bar. (Author/LRW)

Proposes a general stopword list and a simple stemming procedure that can be used to adapt search mechanisms for French-language databases. Describes document-retrieval experiments with French test collections aimed at improving retrieval effectiveness. (LRW)

Considers the need for keyphrase-extraction techniques in intelligent Chinese information retrieval and presents a PAT-tree-based adaptive approach, developed from the PATRICIA Algorithm (Practical Algorithm to Retrieve Information Coded in Alphanumeric). Discusses Internet utilization, automatic term suggestion, domain-specific lexicon…

Describes the implementation of FromTo-CLIR, a Web-based natural-language interface for cross-language information retrieval that was tested with Korean and Japanese. Proposes a method that uses a semantic category tree and collocation to resolve the ambiguity of query translation. (Author/LRW)

Provides a summary look at the features provided by nine major World Wide Web search engines. Examines size, Boolean operators, phrase searching capabilities, media searching, format options, and special features. (LRW)
