摘要： A method and an apparatus for identifying sub-graphs similar to a sample sub-graph from a network, in particular for identifying similar community structures from a network, are disclosed. Specifically, when a sample sub-graph is a community structure, it usually contains a plurality of nodes densely associated with each other. The method proposes first screening the network via key nodes of community structures so as to find sub-graph candidates that are potentially similar to the sample sub-graph, then strictly comparing the sub-graph candidates with the sample sub-graph to find similar sub-graphs of the sample sub-graph.

摘要： A layout method in a display area for multiple graph components in a dynamic network. The multiple graph components are sorted according to their importance into a first subset S1 and a second subset S2 according to the order of their importance. The first subset S1 is divided into an upper subset Cp including only the most important graph component and a lower subset Cm. The display area is divided into display portions S1′ and S2′ proportionally according to the importance values of the first subset S1 and the second subset S2. Display portion S1′ is divided into display portions Cp′ and Cm′ proportionally according to the importance values of the upper subset Cp and the lower subset Cm. The first division and the second division and the corresponding division of the display area are executed iteratively until the aspect ratio of display portion Cp′ is close to 1.

摘要： A method and an apparatus for animating transition among a dynamic graph series including a preceding graph and a succeeding graph which are temporally sequentially displayed. The method includes: selecting an unchanged node which is the nearest to a removed node and merging through animation the removed node with the unchanged node, thereby animating removal of the removed node; and selecting an unchanged node which is the nearest to an added node and splitting through animation the added node from the unchanged node, thereby animating addition of the added node. During the animation, the moving distances of the nodes can be shortened, and the crossing of movement paths and the crossing of graph edges can be prevented during the movement of the nodes, thereby visualizing smoothly and clearly transition among dynamic graph series.

摘要： The visibility of a treemap is improved by offsetting the area of a parent node relative to a bounding box containing all of its child nodes while constructing the treemap, so that a part of the bounding box lies outside the area of the parent node, and the area of each child node in the bounding box is located entirely or partially within the area of the parent node. The present invention highlights the parent-child relationships in the treemap with a cascading effect to make the structural information therein more apparent and easier to recognize.
