A computational framework is presented for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. This article clearly distinguishes between 2 phases of the alignment process: message interpretation and message generation. In the interpretation phase, presuppositions are extracted from…

According to John Thompson, Web 2.0 is here. Having moved away from its roots in a read-only medium, the Internet is now a place where any and all users can create, upload, and transform information. A crucial consideration for Thompson is how this technological transformation will affect the pedagogical practices of institutions of higher…

This digest describes and defines the various components of an expert system, e.g., a computerized tool designed to enhance the quality and availability of knowledge required by decision makers. It is noted that expert systems differ from conventional applications software in the following areas: (1) the existence of the expert systems shell, or…

Describes an interactive simulated hypothetical instructional computer that significantly improves the student's understanding of how a computer works and how high-level language constraints are handled by essentially simple machines. (Author/IRT)

The performance capabilities of the best computer chess programs are compared with their human counterparts with emphasis being placed on machine behavior limits. (Author)

Introduction: Activity theory, developed in the USSR as a Marxist alternative to Western psychology, has been applied widely in educational studies and increasingly in human-computer interaction research. Argument: The key elements of activity theory, Motivation, Goal, Activity, Tools, Object, Outcome, Rules, Community and Division of labour are…

The background and functional capabilities of Stanford's library automation system and the hardware environment in which it operates are described. Prospects for extending BALLOTS to network use are summarized. (Author/PF)

A Computer Integrated Manufacturing System may make it possible for severely disabled people to custom design, machine, and manufacture either wood or metal parts. Programmable automation merges computer aided design, computer aided manufacturing, computer aided engineering, and computer integrated manufacturing systems with automated production…

This article uses figurations taken from popular culture to explore Donna Haraway's concept of cyborg identities, extending this to include childhood. Starting from her identification of the image of the cyborg as an ironic metaphorical response to capitalism, two negative forms of identity are explored in relation to current technological…

This article presents a novel AAC communication aid based on semantic rather than syntactic schema, leading to more natural message construction. Users interact with a two-dimensional spatially organized image schema, which depicts the semantic structure and contents of the message. An overview of the interface design is presented followed by…

Question analysis and search strategy development were broken down into nine steps for answering reference questions. These steps were examined for possible mechanization of the answering process. Such automation was not proved feasible. (LS)

This review of the research on subject access to library collections focuses on the problems of and prospects for improved online subject access to library collections. Summaries of the general findings of studies on library catalog use and catalog users and some reasons for the frequent failure of subject searches in library catalogs are followed…

This paper describes a system which operates on an independent basis as well as connected to communications network, e.g., PLATO and ASCII based communication systems. The system also has facilities for local production and use of PILOT lessons, for support of a generalized programming language (NSBASIC), and for development of graphic sequences.…

The online catalog discussed in this report extends the present microfiche union catalog development by providing online access to bibliographic records for the holdings of the University of California Libraries. The specifications for the user interface through which the library patron communicates with the online systems to locate materials are…
