Abstract: 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.

Abstract: A method and system of producing a visual text summarization. According to the method, a plurality of topics may be extracted from a collection of text documents, where each of the topics comprises a distribution of topic keywords. An importance ranking for each of the topics may be determined, and an importance ranking for each of the topic keywords of a topic may also be determined. A graph may be displayed having a plurality of stacked layers representing a group of topics selected from the plurality of topics based on the importance ranking of the topics. A keyword cloud within each layer of the graph may also be displayed, where the one keyword cloud is a group of topic keywords selected from the extracted topic keywords based on the importance ranking of the extracted topic keywords.
