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 present invention relates to an user profile information data structure for browsing of multimedia data and a multimedia browsing method using the same.The multimedia data browsing method is characterized in that: (a) multimedia data contains a contents description scheme for indexing / browsing based on contents; (b) an user profile includes an user preference description scheme indicating an user-preferred multimedia browsing method or browsing criterion; and (c) multimedia data is browsed by analyzing the user-preferred application description scheme for user-preferred browsing in a corresponding user profile, if the user desires multimedia browsing.

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.

A video summary description scheme for describing video summary intervals by meta data that provides overview functionality, and which makes it feasible to understand overall contents of the original video within a short time, and navigation and browsing functionalities, which make it feasible to search the desired video contents efficiently. A Video Summary DS includes at least one HighlightSegment DS that describes information on a highlight segment corresponding to one of the video summary intervals, wherein the HighlightSegment DS comprises a VideoSegmentLocator DS describing the highlight segment and an ImageLocator DS describing a representative frame of the highlight segment.

A method and system for description of synthetic audiovisual content makes it easier for humans, software components or devices to identify, manage, categorize, search, browse and retrieve such content. For instance, a user may wish to search for specific synthetic audiovisual objects in digital libraries, Internet web sites or broadcast media; such a search is enabled by the invention. Key characteristics of synthetic audiovisual content itself such as the underlying 2d or 3d models and parameters for animation of these models are used to describe it. More precisely, to represent features of synthetic audiovisual content, depending on the description scheme to be used, a number of descriptors are selected and assigned values. The description scheme instantiated with descriptor values is used to generate the description, which is then stored for actual use during query / search. Typically, a user, to search for a needed synthetic audiovisual content initiates a query that is passed on to a search engine that then retrieves the candidate content from one or more databases whose description closely matches the query criteria specified by the user.
