An invention for generating standard description records from multimedia information. The invention utilizes fundamental entity-relation models for the Generic AV DS that classify the entities, the entity attributes, and the relationships in relevant types to describe visual data. It also involves classification of entity attributes into syntactic and semantic attributes. Syntactic attributes can be categorized into different levels: type / technique, global distribution, local structure, and global composition. Semantic attributes can be likewise discretely categorized: generic object, generic scene, specific object, specific scene, abstract object, and abstract scene. The invention further classifies entity relationships into syntactic / semantic categories. Syntactic relationship categories include spatial, temporal, and visual categories. Semantic relationship categories include lexical and predicative categories. Spatial and temporal relationships can be topological or directional; visual relationships can be global, local, or composition; lexical relationships can be synonymy, antonymy, hyponymy / hypernymy, or meronymy / holonymy; and predicative relationships can be actions (events) or states.

A method and system for rendering graphics based on user customizations in a computer graphics application are disclosed. The customizations relate to various properties of one or more graphical elements in the graphic. Such properties include positioning, size, formatting and other visual attributes associated with the graphical elements. These properties may be defined as either semantic properties or presentation properties. Semantic properties are persistent across all graphic definitions. Presentation properties are specific to the graphic definition to which each particular graphic belongs. Thus, a customization to a semantic property of a displayed graphic is preserved in memory for application not only to the currently displayed graphic, but also to all other graphic definitions that may be displayed in the future. In contrast, a customization to a presentation property is only preserved for the currently displayed graphic, and thus not preserved for all other graphic definitions.

A method of automatically matching schemas begins by extracting schemas from sources and targets. Then, source and target attributes are extracted from the schemas. Each source schema will have multiple source attributes and each target schema will also have multiple target attributes. The source attributes and the target attributes are presented as nodes in a bipartite graph. This bipartite graph has edges between nodes that are related to each other. A plurality of similarity scores are defined between each set of related nodes. Each of the similarity scores is based on a different context-specific cue of the attributes that the nodes represent. These context-specific cues can comprise lexical name, semantic name, type, structure, functional mappings, etc. An overall weight is computed for each edge in the bipartite graph by combining the similarity scores of each set of nodes that form an edge. In addition, an optimal matching of the schemas is assembled, so as to indicate the level of similarity between each of the source and target schemas. The optimal matching selects pairs of nodes between source and target schemas that maximizes the number of nodes matched as well as the overall score of match for the nodes selected.

A system for Semantic Simultaneous Tracking, Object Registration, and 3D Mapping (STORM) can maintain a world map made of static and dynamic objects rather than 3D clouds of points, and can learn in real time semantic properties of objects, such as their mobility in a certain environment. This semantic information can be used by a robot to improve its navigation and localization capabilities by relying more on static objects than on movable objects for estimating location and orientation.

A harvester is disclosed for harvesting metadata of managed objects (files and directories) across file systems which are generally not interoperable in an enterprise environment. Harvested metadata may include 1) file system attributes such as size, owner, recency; 2) content-specific attributes such as the presence or absence of various keywords (or combinations of keywords) within documents as well as concepts comprised of natural language entities; 3) synthetic attributes such as mathematical checksums or hashes of file contents; and 4) high-level semantic attributes that serve to classify and categorize files and documents. The classification itself can trigger an action in compliance with a policy rule. Harvested metadata are stored in a metadata repository to facilitate the automated or semi-automated application of policies.

The semantic hierarchy of a document written in a markup language is represented by a hierarchy of elements, which are viewed and edited using a tree view editor. Each element is represented as a node of a semantic tree, to which may be attached a special purpose editor, capable of editing the semantic properties of that particular element. Such special purpose editors handle the single element to which they are attached and may handle a hierarchy of elements that share common properties in the subtree headed by the single element. They offer a visualization of the elements to which they are attached that is not necessarily hierarchical in form.

Embodiments herein include a method, service, apparatus, etc., that automatically generates a coloring book image that includes line drawings defining a small number of color coherent, clearly discriminated, closed regions while preserving the basic semantic properties of the original image. These regions hence can be filled in with colored inks, crayons, paints, etc. The method inputs a color image that can be a photograph, scanned image, etc. The method begins by transforming the color image into a chrominance-luminance space and then performs low pass filtering on the color image that preserves the chrominance edges of the features within the color image. Next, the method segments the color image into the features based on locations of the chrominance edges of the features. Then, the method can merge selected features into other features. After performing any merging, the method identifies the remaining chrominance edges of the features within the image and adds lines along the remaining chrominance edges to form outlines of the features. Then, the method automatically filters out all other data from the image to leave only the outlines and produce a revised image consisting of just the outlines. The revised image of just outlines is then output to the user.
