Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Presents a model for the a priori analysis of natural language queries which uses an algorithm to transform the query into a logical pattern that is used to determine the answerability of the query. The results of testing by a prototype system implemented in PROLOG are discussed. (20 references) (CLB)

Describes a model that displays structures necessary to map between the conceptual and external levels in database management systems, using an algorithm that maps the syntactic representations of tuples onto semantic representations. A technique for translating tuples into natural language sentences is introduced, and a system implemented in…

Explores a method of combining convention and intention by representing conversation structure with conversation MOPs (schematic structures that store conversation rules as generalized episodes associated with goals the episodes achieved). Discusses how conversation MOPs process the opening portion of a dialogue in an interactive advice-giving…

Literature showing the disadvantages of Boolean logic in online searching is reviewed, and research comparing the Filter/Flow visual interface (i.e., a graphical representation of Boolean operators) with a text-only interface is described. A significant difference in the total number of correct queries is reported that favored Filter/Flow. (16…

Describes the development of a demonstration prototype Research Reference Interface (RRI) that was designed to assist novice instructional designers in justifying the instructional decisions of knowledge-based instructional design tools such as expert systems, decision support tools, intelligent job aids, and hypertext systems. Additional…

The ideal traits for an online searcher, as identified in studies by online vendors and suppliers, are discussed: (1) curiosity and a desire to learn, (2) adaptability, (3) comfortableness with the machine interaction process, (4) ability to cope with instances of system failure, (5) patience and persistence, and (6) a logical, thorough,…

The Augmented Human Intellect (AHI) system is a computer-based system designed to store, structure, and retrieve textual information in a way congruent with the characteristics of the individual. It provides for the hierarchical ordering of information and for the manipulation of text through a system of cross-referencing, modification, and…

In an attempt to overcome the lack of natural means of communication between student and computer, this thesis addresses the problem of developing a system which can understand natural language within an educational problem-solving environment. The nature of the environment imposes efficiency, habitability, self-teachability, and awareness of…

Presents an overview of the IR-NLI II system, an expert interface that allows users to access online information retrieval systems and that encompasses user modeling capabilities. Highlights include the design of the system, the structure and content of stereotypes that represent typical classes of users, and construction of user models.…

Discusses the feasibility and advantages of developing an enhancement for document retrieval systems that would automatically impose Boolean syntax on an input set of search terms. An online specification for such an enhancement is presented, based on experimental results using the MEDLINE database. (13 references) (CLB)

Discusses a study that found that people are more willing to disclose personal information to a computer than to a person. As consumer and family researchers, home economists are in a position to recognize, understand, and mold the influence computers will have on us. (JOW)

Describes INVIDO (systeme d' INformations VIsuelles a DOmicile), a graphical tool which was designed and implemented for studying user reactions to the various types of graphic information displays used by videotex systems. Sample display illustrations included depict weather forecasts and sports and lottery results. (Author/JL)

Presents three current areas of research in human relations at Harvard University which may help solve the problems professionals face due to widespread introduction of new information technologies into the work environment. These include organizational learning, information mapping, and principled negotiation. (CT)

Patients were classified into categories using Spitzer and Endicott's computer program for diagnosis. Analyses of variance using single and grouped scales and discriminant analyses predicting category membership suggested that narrow band categorization is better predicted by the Minnesota Multiphasic Personality Inventory than is broad band…
