A multimedia search engine with relevance feedback

摘要

We present here a web-based prototype for the interactive search of items in quality electronic catalogues. The system based on a multimedia information retrieval architecture, allows the user to query a multimedia database according to several retrieval strategies, and progressively refine the system's response by indicating the relevance, or non-relevance of the items retrieved. Once a subset of images meeting the user's information needs have been identified, these images can be displayed in a virtual exhibition that can be visited interactively by the user exploiting VRML technology.
