Patent ID: 10275457

Abstract:
A computer executes a process of: generating co-occurrence-message bunches by summarizing messages based on a relation in which the messages output from an apparatus are mutually output within a predetermined period; classifying the generated co-occurrence-message bunches into groups based on similarity among the co-occurrence-message bunches; determining a first message which is a representative of each of the groups based on an appearance characteristic of a word or a word string included in each message of each of the groups; determining a second message which is a representative of each of the co-occurrence-message bunches and is not repeated based on an appearance characteristic of a word or a word string included in each message in each co-occurrence-message bunch of each of the groups; and outputting the first message determined for the group including each co-occurrence-message bunch and the second message determined for each co-occurrence-message bunch in correlation with each co-occurrence-message bunch.
