The Role of Relevance Feedback in Managing Multimedia Semantics: A Survey

Abstract

Relevance feedback is a mature technique that has been used to take user subjectivity into account in multimedia retrieval. It can be seen as an attempt to bridge the semantic gap by keeping a human in the loop. A variety of techniques have been used to implement relevance feedback in existing retrieval systems. An analysis of these techniques is used to develop the requirements of a relevance feedback technique that aims to be capable of managing semantics in multimedia retrieval. It is argued that these requirements suggest a case for a user-centric framework for relevance feedback with low coupling to the retrieval engine.
