A Retrieval Mechanism for Semi-Structured Photographic Collections

Abstract. In this paper, a new approach for retrieval from semistructured photographic collections is described. We have developed a retrieval model based on the Dempster-Shafer theory of evidence combination. Basic concepts of the Dempster-Shafer theory are explained and the suitability of this theory for information retrieval is explored. A retrieval model for a semi-structured photographic collection is presented. Extensibitity of this retrieval model for multimedia information retrieval is discussed. Integration of database and information retrieval concepts is a major requirement for semi-structured multimedia information retrieval and is accomplished in this model. A novel indexing scheme for photographic materials is described. We use spatial features, which are objects and their location, as photographic features. We. have developed a multi-modal query interface for querying a photographic collection. A prototype system, Epic, has been implemented and is described in this paper...
