摘要： 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.

摘要翻译： 一种生产视觉文本摘要的方法和系统。 根据该方法，可以从文本文档的集合中提取多个主题，其中每个主题包括主题关键词的分发。 可以确定每个主题的重要性排名，并且还可以确定主题中的每个主题关键字的重要性排名。 可以基于主题的重要性排序，显示具有代表从多个主题中选择的一组主题的多个堆叠层的图形。 还可以显示图中每一层内的关键字云，其中一个关键词云是基于所提取的主题关键词的重要性等级从所提取的主题关键词中选择的一组主题关键字。

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.
