Salminen, Airi; Watters, Carolyn – Journal of the American Society for Information Science, 1992
Introduces a hypertext data model for textual databases in which the text is divided into a syntactic structure, which describes the relationships of the text parts, and an access structure, which is generated from the syntactic structure by users' queries. Implementation considerations for the structuring component, retrieval component, and…

Morrissey, J. M.; And Others – Information Processing and Management, 1986
Proposes a "Model of Querying" for users of office filing facilities and discusses its motivation, aspects, attributes, and advantages. A review of current information systems and attempts to combine information retrieval, artificial intelligence, and database management techniques leads to conclusion that no resultant system is adequate…

Rodriguez, Luis J.; Torres, M. Ines – Language and Speech, 2006
Previous works in English have revealed that disfluencies follow regular patterns and that incorporating them into the language model of a speech recognizer leads to lower perplexities and sometimes to a better performance. Although work on disfluency modeling has been applied outside the English community (e.g., in Japanese), as far as we know…

Bates, Marcia J. – Online Review, 1989
Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Spiegler, Israel; Elata, Smadar – Information Processing and Management, 1988
Presents a model for the a priori analysis of natural language queries which uses an algorithm to transform the query into a logical pattern that is used to determine the answerability of the query. The results of testing by a prototype system implemented in PROLOG are discussed. (20 references) (CLB)

Yannakoudakis, Emmanuel J.; Attar-Bashi, Hussain A. – Journal of Documentation, 1989
Describes a model that displays structures necessary to map between the conceptual and external levels in database management systems, using an algorithm that maps the syntactic representations of tuples onto semantic representations. A technique for translating tuples into natural language sentences is introduced, and a system implemented in…

Agosti, M.; And Others – Information Processing and Management, 1992
Proposes a conceptual reference architecture for information retrieval systems and discusses functional capabilities of a hypertext environment, based on the proposed architecture, for interaction with large textual databases. Functions of the prototype system HYPERLINE are described, and an example of a user session is provided. (17 references)…

Zipperer, W. C. – 1975
Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in…

Crawford, R. G.; Edwards, Mary-Ellen – Online Review, 1985
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.…

Mukhopadhyay, Uttam; And Others – Journal of the American Society for Information Science, 1986
MINDS (Multiple Intelligent Node Document Servers) is a distributed system of knowledge-based query engines for efficiently retrieving multimedia documents in an office environment of distributed workstations. By learning document distribution patterns and user interests and preferences during system usage, it customizes document retrievals for…

Fayen, Emily – Library Hi Tech, 1983
Describes development of an online catalog for Dartmouth College Libraries by Dartmouth and Bibliographic Retrieval Services (BRS). Highlights include Dartmouth parameters; capability of creating a fully inverted file for entire bibliographic citation provided by BRS software; features of BRS/Dartmouth user interface; telecommunications links; and…

Belkin, Nicholas J.; And Others – Information Processing and Management, 1993
Discusses information retrieval as an inherently interactive process utilizing a variety of information-seeking strategies on informational and meta-informational levels. An interface design for a bibliographic information retrieval system, called BRAQUE (BRowsing And QUEry), that supports user interactions in a two-level hypertext environment is…

Moline, Judi – 1991
This report presents a model combining the emerging technologies of hypertext and expert systems. Hypertext is relatively unexplored but promises an innovative approach to information retrieval. In contrast, expert systems have been used experimentally in many different application areas ranging from medical diagnosis to oil exploration. The…

Watters, C. R.; And Others – Online Review, 1985
Describes prototype system that provides retrieval from hierarchically structured full-text databases such as legal statutes and regulations and engineering standards. Enhanced retrieval is provided through integration of three different access techniques dependent on inherent hierarchical text structure: menu, Boolean combination of keywords,…

Harry, D. P.; And Others – 1979
The Voice Interactive Analysis System study continued research and development of the LISTEN real-time, minicomputer based connected speech recognition system, within NAVTRAEQUIPCEN'S program of developing automatic speech technology in support of training. An attempt was made to identify the most effective features detected by the TTI-500 model…
