Abstract

Much previous research on improving information retrieval applications has focused on developing entirely new systems with advanced searching features. Unfortunately, most users seldom utilize these advanced features. This research explores the use of a software agent that assists the user during the search process. The agent was developed as a separate, stand‐alone component to be integrated with existing information retrieval systems. The performance of an information retrieval system with the integrated agent was subjected to an evaluation with 30 test subjects. The results indicate that agents developed using both results from previous user studies and rapidly modeling user information needs can result in an improvement in precision. Implications for information retrieval system design and directions for future research are outlined.

Abstract

This chapter reviews published studies of the use of pictorial information. Examining image user studies surfaces several research questions often addressed by this body of work, as well as some frequently encountered problems. These questions and problems organize this survey of the literature. Image user studies were included in two valuable reviews of digital image research and development, published by Christie Stephenson and Corinne Jörgensen in 1999 (Jörgensen, 1999; Stephenson, 1999). This overview considers research since that time, focusing on assessment that was not targeted at a single system or service. While attempting to incorporate some interesting research from the information and educational technology communities, this discussion of image delivery as an aspect of digital library development limits coverage of those important literatures.
