Title

Evaluation of image retrieval systems : role of user feedback

Abstract

Intellectual access to a growing number of networked image repositories is but a small part of the much larger problem of intellectual access to new information formats. As more and more information becomes available in digital formats, it is imperative that we understand how people retrieve and use images. Several studies have investigated how users search for images, but there are few evaluation studies of image retrieval systems. Preliminary findings from research in progress indicate a need for improved browsing tools, image manipulation software, feedback mechanisms, and query analysis. Comparisons are made to previous research results from a study of intellectual access to digital art images. This discussion will focus on the problems of image retrieval identified in current research projects, report on an evaluation project in process, and propose a framework for evaluation studies of image retrieval systems that emphasizes the role of user feedback.
