Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

This introduction to online numeric database systems describes the types of databases associated with such systems, shows the major functions which they can perform (retrieval, analysis, display), and identifies the major characteristics of user interfaces. Examples of numeric database use are appended. (EJS)

Discusses rise of videotex and teletext systems (delivery of graphic and textual information through electronic systems) in the United States, noting the role of libraries and librarians in providing these services. Corporate involvement, U.S. markets, library reference services, and major issues confronting growth are noted. Two references are…

Examines several alternative document summarization techniques to determine which is the most effective for saving time when a human judge must certify the output of an automatic categorization system. That is, how useful is the summarization technique as compared to reading the entire document. Users in this case are molecular biologists wanting…

Using as a backdrop Vannevar Bush's 1945 discussion of the "Memex," his proposed system for organizing and storing information, this paper considers the development of intelligent multimedia knowledge systems. Particular attention is focused on learner needs and intentions in information seeking, and the implications of these factors for…

This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half…

Through a description of an imitation career, the author introduces the complexities involved in programming a man-machine system which facilitates individualized career development. The interaction of man and machine is programmed, in the imitation career, because the individual descriptions of events in career chronologies, vitae and…

The career decision making paradigm underlying the Information System for Vocational Development (ISVD) is briefly stated; it reflects the fact that a person has different information needs associated with different life stages, and with decision making stages within any given life stage. The greater portion of the report deals with the attempts,…

Discusses the CODER system, which was developed to investigate the application of artificial intelligence methods to increase the effectiveness of information retrieval systems, particularly those involving heterogeneous documents. Highlights include the use of PROLOG programing, blackboard-based designs, knowledge engineering, lexicological…

This paper reviews the history of separate online system interfaces which led to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research on such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval. (Author/EJS)

The SilverPlatter system is a complete, stand-alone system, consisting of an IBM (or compatible) personal computer, compact disc with read-only memory (CD-ROM) drive, software, and one or more databases. Large databases (e.g., ERIC, PsycLIT) will soon be available on the system for "local" installation in schools, libraries, and…

Discussion of database design that allows wider range of capabilities than conventional information retrieval database covers prestructuring of searches to pinpoint target items, which are selected from browseable display, and navigation capability, which allows user to move from record to record within database to facilitate extraction of…

Discussion of the effect on the workforce of the application of electronic data processing technologies to information handling activities highlights task specialization; white collar alienation; feelings of powerlessness, meaninglessness, and normlessness in workers; the chronology of automation; and experimentation and communication. Nineteen…

This paper describes an evaluation of the Kea automatic keyphrase extraction algorithm. Tools that automatically identify keyphrases are desirable because document keyphrases have numerous applications in digital library systems, but are costly and time consuming to manually assign. Keyphrase extraction algorithms are usually evaluated by…

Discussion of the importance of adhering to standards in the library community focuses on standards related to linking systems, such as bibliographic utilities and circulation systems, and online catalogs. Three areas in particular are highlighted: (1) communications standards; (2) data format standards; and (3) user interface and indexing…
