Abstract:
Interactive information retrieval (IIR) is concerned with helping people find
information via automated retrieval systems through interactions. IIR research addresses three major problem
areas (1) understanding information seeking needs and behaviors;
(2) developing retrieval systems that respond to information needs and support
information seeking behaviors and interactions; and
(3) developing methods and measures to study and evaluate behaviors,
interactions and systems.
In this talk, I provide an overview of some IIR research projects which I've been involved with that address these problem areas. Projects addressing the first two areas are presented briefly. These projects examined explicit and implicit feedback and enhanced queries. An in-depth look at a recent study addressing the third area is then presented. This study examined the standard IIR system evaluation model and the variance introduced by this model on users' evaluation behaviors. In this study, sixty users completed three recall-oriented search tasks. Standard evaluation questionnaires were completed by users after each search task and at the end of the experimental session. Before completing the final questionnaire, some users were provided with feedback about their performances: some were told they did very well, some were told they did very poorly, some were told their actual performances and some were not provided with any feedback. Results and implications of this study are discussed.
