Tests the relative efficiency and learning effect of text, pictures, and animation in online help systems, designing six versions of a help system for telephones. Presents operational information in text, pictures, or animation, with or without spatial information. Shows that presenting operational information via text was most efficient and that…

This paper reports the results of a controlled field experiment in which voice communication was introduced into an existing online community (online gaming guilds within the popular game "World of Warcraft"), comparing a mix of voice and text with text only. Quantitative results suggest increases in liking and trust due to the addition of voice,…

Analyzes recent developments in the problem of processing queries expressed as Boolean expressions, shows that the concept of threshold values resolves the problems inherent with relevance weights, and explores possible evaluation mechanisms for document retrieval based on fuzzy set theory. Sixteen references are listed. (FM)

Explores what might be the optimal query expansion (QE) processing method with semantically coded thesauri. Examines whether QE via semantically coded thesauri terminology is more effective in the "automatic" or "interactive" processing environment. Results revealed that synonyms and partial synonyms and narrower terms are…

BELLTIP is an on-line library processing system concerned with book acquisitions, cataloging, and financial accounting for a newwork of 26 technical libraries. At its center is an interactively updated and queried set of files concerned with all items currently in process. Principal products include all purchase orders, claims, and cancellations;…

A review of the history of libraries from the viewpoint of a speaker in the year 2080 describes the opposing trends of a shift of human values toward individuality and diversity, while technology was becoming more uniform. Man-computer relationships steadily replaced people-to-people relationships. While the cost of contact services rose,…

This paper considers the processing of digital library queries, consisting of a text component and a structured component in distributed environments. The paper concentrates on the processing of the structured component of a distributed query. A method is proposed to identify the databases that are likely to be useful for processing any given…

Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

An obvious and natural approach to organizing a large corpus of data is a hierarchical index--akin to a book's table of contents. The type of corpus dealt with here is a bibliographical repository, with entries form a limited domain. Given such an index, it is desirable that search results point to relevant locations in the hierarchy, rather than…

Reviews a study which examined computerized bibliographic centers in Canada identifying three types: (1) library processing facility; (2) library network user group; and (3) information retrieval facility. The study also reported on ways to promote a computerized library network with emphasis on national location service. (CWM)

Applies theories about organizational information processing to better understand the influences on method of access and on effects of using online information. Explores the extent to which organizational differences also influence these variables, what the positive and negative outcomes from using online commercial databases are, and how those…

The periodic TRECs (Text Retrieval Conferences) have reported the results of a variety of recall studies in large-scale document retrieval. While the efforts of TREC are noteworthy and laudable, there are reasons why its results, especially the recall values that are central to its conclusions, should be accepted with some caution. (Contains 17…

An executive summary (chapter 1) provides an overview of this study to assess the needs and requirements of Educational Radio and Television of Iran (ERTI), and to analyze alternative information systems and services that could be used to facilitate the storage and retrieval of reports, books, films, and tapes in that organization. Chapter 2…

In 1982 a study was conducted to analyze educational software information currently available to Canadian educators and to develop a plan for effectively collecting, organizing, and disseminating courseware information in the future. The teachers, students, librarians, educational resource personnel, and administrators included in the study…

Examines the knowledge construction processes of novice programmers using parentheses and quotes in hypermedia; identifies characteristics of successful and unsuccessful students working off- and on-line. The strategies of perceptual matching and computer feedback were used in both settings to interpret of the information presented. (Author/AEF)
