Using Multiple Viewpoints to Improve Retrieval Effectiveness in Content-Based Image Retrieval

A viewpoint is any representational scheme on some collection of data objects, together with a mechanism for accessing this content. Thus a viewpoint is any structure from which we can elicit an informative result from a collection of data by presenting a query. A multiple viewpoint system allows a searcher to pose queries to one viewpoint and then change to another viewpoint while retaining context. This is a very general framework that is applicable to any information retrieval system.
