Abstract: An information processing system (1) includes an account-opening task server (100) and an agent server (200), wherein the server (100) includes a transmission unit (102) that transmits, to the server (200), when storing personal information of a user in a personal information database (120), first authentication information for logging in the server (100) with respect to the user and a processing unit (104) that executes, when receiving the first authentication information, processing of reading the user information of the user, and the server (200) includes an ID registration unit (202) that stores second authentication information for the user to log in to the server (200) in an ID storage unit (220) in association with the first authentication information and a login unit (204) that reads, when receiving the second authentication information, the first authentication information corresponding to the second authentication information from the ID storage unit (220) and logs in to the server (100).

Abstract: The present invention can provide a technology for presenting information that indicates contents and trends of many messages without a need to define a portion that varies among the messages in advance. A message analysis apparatus is provided with a clustering unit, a field analysis unit, and a pattern generation unit. The clustering unit classifies a message set that is an aggregation of messages each being formed of one or more fields, into a cluster, based on similarity among the messages. The field analysis unit identifies, in each of fields that form a message group in the cluster, a variable portion in which a value in the field varies and an invariable portion in which a value in the field does not vary. The pattern generation unit generates a message pattern being common to the message group in the cluster, based on the variable portion and the invariable portion.

Abstract: A credit and debit log analysis device includes a credit and debit log storage unit (11) that stores a history of credit to an account of a customer to be an analysis object and debit to the account as a credit and debit log, a calendar (15) that stores information on a date, a trend discovering unit (12) that discovers a trend of credit and debit based on the credit and debit log and the calendar, a trend storage unit (13) that stores the trend, a matching rule generating unit (14) that generates a matching rule based on the trend so as to detect credit and debit data contravening the trend, a matching rule storage unit (16) that stores the matching rule, a matching unit (17) that detects a premonition by comparing the credit and debit data and the matching rule, a premonition storage unit (18) that stores the premonition, and a presentation unit (19) that presents the premonition to a user.
