An information processing apparatus (1) includes a first network information acquisition unit (160) that acquires first network information (100) including plural event nodes (101) and event links (102) each connecting one pair of event nodes (101) involved in an event, among the plural event nodes (101), a second network information acquisition unit (162) that acquires second network information (110) including at least two time links each connecting the plural event nodes (101) and plural time nodes (111), and the one pair of event nodes (101) and the time nodes (111) indicating a time of occurrence of the event, and a second community generation unit (163) that generates one or more second communities to which the plural event nodes (101) and the plural time nodes (111) belong, for the second network information (110). |
