<P>PROBLEM TO BE SOLVED: To favorably support finding useful information in a document by making a document containing a plurality of types of items in sentences a target document to be visualized and effectively using the point that one item is collectively described at one place in the document. <P>SOLUTION: Trouble cases are read in by a document reading section 12 and texts are extracted. The importance (relevance) of a pair of two words in the text is calculated by a pair importance calculating section 14. The words having the high part importance are mutually coupled by a link, and a graph of node group is generated by a graph generating section 16. A user selects and operates the graph as a deletion or trouble case. The classification result as the selection result is stored in a database 18. In calculating the pair importance by the pair importance calculating section 14, for the trouble case document in which each of a plurality of items, such as phenomena, causes, measures is structured, the pair importance is calculated using an evaluation function where the more the number of distances with the set of small distances of two words be, the higher the importance becomes. <P>COPYRIGHT: (C)2010,JPO&INPIT |
