Finding the Best Picture: Cross-Media Retrieval of Content
نویسندگان
چکیده
We query the pictures of Yahoo! News for persons and objects by using the accompanying news captions as an indexing annotation. Our aim is to find these pictures on top of the answer list in which the sought persons or objects are most prominently present. We demonstrate that an appearance or content model based on syntactic, semantic and discourse analysis of the short news text is only useful for finding the best picture of a person of object if the database contains photos each picturing many entities. In other circumstances a simpler bag-ofnouns representation has a good perfoprmance. The appearance models are tested in a probabilistic ranking function.
