Abstract

Presents a 3 dimensional model of information exploration. An attempt is made to clarify the respective roles of the human and the system in browsing and information retrieval, and to characterise alternative interaction styles to maximise retrieval effectiveness. Illustrates the applicability of the model of exploration by describing 8 paradigmatic cases of information exploration that represent different vertices of the model. Describes initial experiment that attempted to assess the pragmatic impact of various combinations of exploration features. Discusses methods for integrating hypermedia and information retrieval into general information exploration systems and discusses some of the processes that people use in information exploration. Argues for the development of hybrid information systems combining exploration features in the most appropriate way according to the task needs of users

Abstract

Examines the implementation of the newspaper metaphor in an information exploration interface. The newspaper metaphor is an appropriate interface papradigm for large-scale full-text databases. This metaphor is appropriate for large automatically generated hypertexts, independent of the nature of their content. Describes VOIR, a softwre prototype that is used as an electronic newspaper workbench. The program constructs newspaper pages interactively, and allows user to specify their information seeking intent in a variety of ways, including graphical Boolean queries, hypertext links, and typed-in queries. Reports some empirical evidence that indicates that users perform better when they are shown more articles simultaneously. These results suggest that the newspaper metaphor may be an effective organizing principle for a class of information exploration tasks. Discusses some implications for hypertext and information retrieval in general
