| Abstract(in English) | The query-by-example approach can be considered as partially supervised learning, where a retrieval model for a query is extrated by using positive examples provided by a user and unlabeled examples. For accurate retrieval, it is crucial how to select negative examples from unlabeled examples. We select negative examples which are highly similar to positive examples, because they are useful for denning the boundary between relevant and irrelevant shots. Such negative examples are selected by iteratively building SVMs, which are used to examine whether unlabeled examples are dissimilar to positive examples. The proposed method is tested on TRECVID 2009 video data. |
