<P>PROBLEM TO BE SOLVED: To suggest the tendency of a whole text unit aggregation by graphically indicating a plurality of representative words in the whole text unit aggregation to be analyzed, and relations among the words. <P>SOLUTION: A word appearance data storage part 150 holds word appearance data which indicates which message includes the word. A frequency calculating part 170 calculates how many messages exist in the object message aggregation, where the respective object words appear. A word specifying part 180 specifies L number of words with the first to L-th frequencies, based on the frequencies calculated by the frequency calculating part 170. A partial aggregation deriving part 160 derives partial aggregations, specifies the corresponding words, and generates node data and link data. A graphic display part 190 acquires the node data and the link data from the partial aggregation deriving part 160, determines a graphic network structure, and performs graphic display. <P>COPYRIGHT: (C)2009,JPO&INPIT |
