Instead of focusing on specific, static semantic description schemes, emphasis and focus is placed on determining what is necessary and needed to create any type or kind of semantic description for content data in various applications such as MPEG-7. In particular, numerous semantic description tools are selected after examining the principles of cognitive science and category theory. These semantic description tools provide sufficient flexibility and power to create any type or kind of semantic description. Semantic entity tools and categorical structure tools were identified as necessary and needed to create any type or kind of semantic description. Semantic entity tools are tools that represent entities in a semantic description. Categorical structure tools are tools that represent categorical structures of semantic entities and relations among these categorical structures. The semantic entity tools and the categorical structure tools facilitate creation of a semantic mosaic description for content data from multiple semantic descriptions.

The invention provides a system and method for integrating multimedia descriptions in a way that allows humans, software components or devices to easily identify, represent, manage, retrieve, and categorize the multimedia content. In this manner, a user who may be interested in locating a specific piece of multimedia content from a database, Internet, or broadcast media, for example, may search for and find the multimedia content. In this regard, the invention provides a system and method that receives multimedia content and separates the multimedia content into separate components which are assigned to multimedia categories, such as image, video, audio, synthetic and text. Within each of the multimedia categories, the multimedia content is classified and descriptions of the multimedia content are generated. The descriptions are then formatted, integrated, using a multimedia integration description scheme, and the multimedia integration description is generated for the multimedia content. The multimedia description is then stored into a database. As a result, a user may query a search engine which then retrieves the multimedia content from the database whose integration description matches the query criteria specified by the user. The search engine can then provide the user a useful search result based on the multimedia integration description.

A method for transforming Video-To-Text is disclosed that automatically generates text descriptions of the content of a video. The present invention first segments an input video sequence according to predefined semantic classes using a Mixture-of-Experts blob segmentation algorithm. The resulting segmentation is coerced into a semantic concept graph and based on domain knowledge and a semantic concept hierarchy. Then, the initial semantic concept graph is summarized and pruned. Finally, according to the summarized semantic concept graph and its changes over time, text and / or speech descriptions are automatically generated using one of the three description schemes: key-frame, key-object and key-change descriptions.
