Implicit Feedback: Using Behavior to Infer Relevance

This chapter presented a framework for understanding and studying how behavior can be used as implicit relevance feedback, and a discussion of key issues and problems associated with implicit feedback research and identified challenges for future research.

Abstract

The chapter presented a framework for understanding and studying how behavior can be used as implicit relevance feedback. This included a classification and discussion of behaviors that have been used as implicit relevance feedback, a general discussion and characterization of implicit feedback research, and a presentation of example studies to illustrate how such studies have been conducted and how feedback has typically been measured and used. Finally, this chapter presented a discussion of key issues and problems associated with implicit feedback research and identified challenges for future research. The use of behavior as implicit relevance feedback is an exciting and promising approach to personalizing IR interactions. Although more effort needs to be made to fully understand how behaviors can be used as implicit relevance feedback, current research efforts offer a promising start.
