DAEDALUS at ImageCLEF Wikipedia Retrieval 2010: Expanding with Semantic Information from Context

This paper describes the participation of DAEDALUS at the ImageCLEF 2010 Wikipedia Retrieval task. The main focus of our experiments is to evaluate the impact in the image retrieval process of the incorporation of semantic information extracted only from the textual information provided as metadata of the image itself, as compared to expanding with contextual information gathered from the document where the image is referred. For the semantic annotation, DBpedia ontology and YAGO classification schema are used. As expected, the obtained results show that, in general, the textual information attached to a given image is not able to fully represent certain features of the image. Furthermore, the use of semantic information in the process of multimedia information extraction poses two hard challenges still to solve: how to automatically extract the high level features associated to a multimedia resource, and, once the resource has been semantically tagged, which features must be used in t...
