Abstract

Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

Abstract

Reports on work in progress to define an object oriented model of a probabilistic information retrieval system (OKAPI), the central component of which is the query itself. Considers how to represent queries both internally and at the user interface level, and their relationship with other components of the model. The model will form the basis of a configurable user interface, which allows controlled experiments to be undertaken, and could be adapted to the needs of different users accessing different databases. Implementation will involve the use of a high level interpreted scripting language for overall control, communicating with an internal model and an interface model, designed and developed using object oriented techniques
