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…

Rapid proliferation of different types of interaction devices that use more natural channels (voice, touch, gesture) for interfacing with the digital medium illustrates the trend towards the creation of more "humane" interaction mechanisms. However, the current historical paradox is that modern technological advances are dramatically…

Describes expert systems which are computer programs which use inference schemes to apply generalized human expertise to the facts of a specific case. Basic concepts, potentials and implications are presented along with the issues involved in their development and use. A simple expert system, written in BASIC, is included to illustrate the…

Discusses the trend toward ubiquitous computing and the challenge to enhance the behavior of any application by informing it of the context of its use. Defines context related to the interaction between humans, applications, and the surrounding environment; and presents a conceptual framework and a toolkit for supporting the rapid prototyping of…

Discusses the possibility and usefulness of applying Habermas' universal pragmatics to analyze information retrieval interaction. Examines current studies of human computer interaction (HCI) and presents a case study that investigated the initiation and development of verification of validity claims in HCI from the universal pragmatics…

A common command language has been proposed for use by systems designers and those developing new user interfaces. There is controversy over the appropriateness of a standard command language, and those who are working in artificial intelligence believe that natural language interfaces will make it unnecessary for users to learn such a language,…

Reviews two software products--INSTANTCOM and PC WRITE--that work well in tandem and possess the following capabilities: make logon easy and memory-independent; allow prewritten search statements to be uploaded; allow downloading of results; permit easy editing and other data management options. Examples done on the IBM PC/AT are provided. (EJS)

Presents a fuzzy evaluation method of SGML documents based on computing with words. Topics include filtering the amount of information available on the Web to assist users in their search processes; document type definitions; linguistic modeling; user-system interaction; and use with XML and other markup languages. (Author/LRW)

Discussion of users of information retrieval systems focuses on a machine-learning approach to inferring the user's context in the Okapi system. Results of an evaluation experiment are given, and it is concluded that context learning can help information retrieval systems adapt to users' particular queries. (Author/LRW)

Proposes a three-level framework for classifying elearning (electronic learning) interactions in distance education. Illustrates how the framework may be used to design and sequence electronic learning interactions, analyze planned interactions to reduce the need for costly revisions, and organize research to help interpret findings and guide…

Discusses how to design effective user interfaces for computer-based training (CBT) programs. Four types of interfaces are described: presentation, including consistency; conversation, including feedback and flexibility; navigation; and explanation, including online help. A job aid for evaluating CBT interfaces is included. (Contains 13…

The first of two articles discusses virtual reality (VR) and online databases; the second one reports on an interview with Thomas A. Furness III, who defines VR and explains work at the Human Interface Technology Laboratory (HIT). Sidebars contain a glossary of VR terms and a conversation with Toni Emerson, the HIT lab's librarian. (LRW)

Discusses a new, informational-based cybernetic conception of the early development of child consciousness. Suggests a solution to the fundamental problem of formulating and creating the optimal cognitive preconditions of successful child-computer interaction, and analyzes some negative aspects of using intelligent computer and communications…

Presents an efficient spoken-access approach for both Chinese text and Mandarin speech information retrieval. Highlights include human-computer interaction via voice input, speech query recognition at the syllable level, automatic term suggestion, relevance feedback techniques, and experiments that show an improvement in the effectiveness of…
