A Conceptual Graph Approach for Video Data Representation and Retrieval

We present in this paper a video representation and retrieval model using the conceptual graphs and based on the characteristics of the perception of video content in time.We propose a new semantic structure for video content representation based on the notion of event. This new vision of content representation takes into account the different levels of abstraction of video content. On the other hand the model covers the temporal dimension of video and so presents a temporal model based on two time dimensions defined as video and story time.
