ABSTRACT:
A system and method for generating responsibility vectors associated with multi-media files (e.g., audio and/or video files) is provided. The responsibility vectors are based upon responsibility of mixture components fitted to a mixture model for frames of the files. The responsibility vectors can be grouped based upon clustering related to extracted identifiable features of frames of the multi-media files. Once generated, responsibility vectors can be searched by a multi-media searching system.Also provided is a system for multi-media searching based, at least in part upon responsibility vectors associated with a query segment and multi-media files. The system can generate a query profile based, at least in part, upon responsibility vectors of frames of the query segment. The system can further generate segment profiles of segments of the multi-media files. The system can then provide information associated with a likelihood that a particular file of the multi-media files includes the query segment based, at least in part, upon the query profile and a segment profile of the particular file.
