Examines the potential of online methods for hypermedia research that allow the recording, analysis, and interpretation of learner/hypermedia interaction. Discusses discourse comprehension research, comprehension of printed text, reading time, verbal protocols, event-related potentials, and interaction protocols in hypermedia research. Contains 56…

Explores the utility of using prior domain knowledge (in the form of taxonomies over attributes, attribute values and concept classes) to constrain the rule learner's search by requiring it to be consistent with what is already known about the domain. Spreading Activation Learning (SAL) is used to efficiently learn over taxonomically structured…

Presents an interaction model and an experimental method for information retrieval. This automated method helps identify which user and system variables are relevant, which are independent of other variables, and which ranges of the variables are most important. Results show that relevance feedback consistently improves retrieval performance. (AEF)

Controlled experiments were conducted with an enhanced experimental intermediary system, CONIT (COnnector for Networked Information Transfer), to test how effective such a system could be in assisting end users in online searching of medical and biomedical literature. A total of 16 end users, none of whom had previously operated CONIT or any of…

Results from one of a series of cooperative projects to study public access to online catalogs are discussed. This report focuses on a survey of 1,152 users and 1,315 non-users of six computer systems at seven libraries, with library participants including (1) Claremont Colleges Library, which uses the Claremont Total Library System; (2) the…

This paper follows the evaluation of a system of student performance analyses programs which has advanced from a crude manual system to an easy to use, on-line, interactive system. Recently, emphasis has focused upon the development of a system which requires little computer expertise on the part of the author to obtain a concise, easy to read…

This essay focuses on use of the Library of Congress Subject Headings system in online catalogs for the retrieval of information by subject. Among the topics addressed are differences among catalog forms (card, microform, and computer); user interface with different forms of catalog; the types of subject indexes employed in present online…

The keynote address, given by Michael Allen, characterized the association as a group of devoted humanitarians who are committed to finding realistic educational and training alternatives. He discussed the potential role of computer-based education specialists in meeting general and specific instructional needs. Included in the proceedings are 59…

This paper describes the philosophy of intelligent instructional systems and presents an example of one such system in the domain of manipulative mathematics--BLOCKS. The notion of BLOCKS as a paradigmatic system is explicated from both the system development and educational viewpoints. From a developmental point of view, the modular design of…

NLS-SCHOLAR is a prototype system that uses artificial intelligence techniques to teach computer-naive people how to use a powerful and complex editor. It represents a new kind of computer-assisted instruction (CAI) system that integrates systematic teaching with actual practice, i.e., one which can keep the user under tutorial supervision while…

The technical feasibility of a continental information network for astronomy has been demonstrated in the course of a two-month experiment conducted jointly by Dearborn Observatory of Northwestern University and the Stanford University Computation Center. The experiment simulated a scientific information network based on a high-level retrieval…

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.…

Examines role and contributions of natural-language processing in information retrieval and artificial intelligence research in context of large operational information retrieval systems and services. State-of-the-art information retrieval systems combining the functional capabilities of conventional inverted file term adjacency approach with…

This 910-item annual update (1984 through early 1985) covers: online systems, databases, services; man-machine studies, database creation, user interface, system design and evaluation; profile development, searching techniques, indexing; usage studies, economics, promotion, online searching services management; user training, microcomputer…

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…
