Presents a concept of end-user query language with facilities for expressing relationships between objects kept in a database. The idea of nesting these features in typical document query language is shown. Examples of usage of these new facilities are included. (Author/MBR)

Describes the Case Hierarchy, a model of the case system of unconstrained natural language, and ways in which the case system is specialized in a restricted domain. Results of a feasibility study which examined the utility of the Case Hierarchy and the Case Hierarchy Tool (an intelligent editor supporting the domain analysis process) are…

The automation of online order retrieval for Chemical Abstracts Service Document Delivery Service was accomplished by shifting to an order retrieval/dispatch process linked to a Unix network. The Unix-based environment, its terminal emulation, page-break, and user-friendly interface software, and later enhancements are reviewed. Resultant increase…

Examines general technical issues involved in placing latest computer systems, operable by end users in programer-free environment, at disposal of non-English-speaking users. User environment, classification of software products (token dependent, communications intensive, language dependent), approaches to bilingual software modification,…

Like a table of contents in print material, a computer-presented menu presents information. It informs a user of the topics that are available. Some menus present information by categories and thus communicate the organization as well as the content of the program. In addition to providing information, menus serve as a selection and retrieval…

This article analyzes the front end software marketplace and discusses some of the complex forces influencing it. Discussion covers intermediary market; end users (library customers, scientific and technical professionals, corporate business specialists, consumers); marketing strategies; a British front end development firm; competitive pressures;…

Four information retrieval packages that run on single user microcomputers--CAIRS, INMAGIC, Sci-Mate, SIRE--are examined based on following criteria: storage requirements; hardware requirements; search features (Boolean logic, comparison searching, set building, truncation, and wild card characters); system output; security; system maintenance…

Discusses major features and capabilities of gateway software--microcomputer software packages that act as interfaces between users and bibliographic retrieval systems they are searching--i.e., communication, interface, auxiliary programs. Four programs (In-Search, Universal Online Searcher, Search Helper, microDisclosure) are reviewed and…

Discusses natural language retrieval systems, focusing on West Publishing Company's WIN (Westlaw Is Natural) system used with its case law database. Information retrieval models, the advantages and disadvantages of natural language retrieval, and the use of the approach by Congressional Quarterly's Washington Alert, Personal Librarian, and other…

Presents specifications for software that is designed to support manual development and maintenance of information retrieval thesauri. Evaluation of existing software and design of custom software is discussed, requirements for integration with larger systems and for the user interface are described, and relationships among terms are discussed.…

Describes how online searchers can use a software tool based on back-of-the-book indexes to assist in dealing with search engine databases compiled by spiders that crawl across the entire Internet or through large Web sites. Discusses human versus machine knowledge, conversion of indexes to mind maps or mini-thesauri, middleware, eXtensible Markup…

This study was designed to be a state-of-the-art survey and investigation of intelligent "front end" design approaches and software for improving subject access and subject searching in today's large online bibliographic retrieval systems and online public access catalogs (OPACS). The report begins with an illustrated overview of…

Discusses the need for a rich semantics for the user interface in interactive image retrieval and presents two methods for building such interfaces: possibility theory applied to fuzzy data retrieval, and a machine learning technique applied to learning the user's deep need. Prototypes developed using videodisks and knowledge-based software are…

Brief description of videotex systems is followed by recommendations for the design of database structure, command language, and screen format. How users search through the database is described and evaluations of the underlying tree structure are reviewed. Information sources on other aspects of videotex besides usability are listed. (MBR)

The Drug-Interface, prototype system built to facilitate retrieval of drug related information, automatically connects to DIALOG Information Retrieval Service via available networks, aids user in formulating and/or revising search strategy, sends query to DIALOG, displays results of search, and downloads relevant pieces into Macintosh data file.…
