Motivated by the needs of semantic search and retrieval of multimedia contents, operating directly on the video based annotations can be thought as a reasonable way for meeting these needs as video is a common standard providing a wide multimedia content description schema. Raw data and lowlevel features alone are not satisfactory to fulfil the user's requirements; that means, a deeper understanding of the content at the semantic level is necessary. A semantic content extraction system that

In automatic extraction process, starts with object and define class for each process in video data. Objects extracted from consecutive representative frames are processed to extract temporal relations. In addition to that, additional rule to lower spatial relation computation cost and to be able to define some difficult situations more successfully is used. Event extraction process uses objects. Similarly, objects and events are used in concept extraction process.
