We propose a hybrid approach integrating textual search with content-based retrieval. We show how a preliminary double clustering of image corpus exploited by an adequate retrieval process constitutes an answer to the pursued objective. The retrieval process takes advantage of user-system interaction via relevance feedback mechanism whose results are integrated in a virtual image. Experimental results on the PICAP prototype are reported ed and discussed to demonstrate the effectiveness of this work.}, identifier = {02086526}, }
