Although any unimodality type partially expresses limited semantics less or more, video semantics are fully manifested only by interaction and integration of any unimodal. Video data comprises plentiful semantics, such as people, scene, object ,event and story, etc. A great deal of research has been focused on utilizing multi-modality features for better understanding of video semantics. Proposed in this paper is a new approach to detect semantic concepts in video using co-occurrence data embedding, SimFusion, and locality preserving projections from temporal associated co-occurring multimodal media data in video.
