Abstract
An access source classification apparatus has: a first calculation unit that calculates a statistic related to access to each service by each access source based on a set of access logs indicating access to any service of a plurality of services by any access source of a plurality of access sources; an extraction unit that, for each of the services, calculates an index value indicating distribution of access status to the service for each of the access sources based on the access logs related to the service, and extracts some services based on the index value; a second calculation unit that calculates relevance between each access source and each service extracted by the extraction unit by applying a clustering approach to the statistic; and a classification unit that classifies an access source to any service extracted by the extraction unit into any of groups each including one or more access sources based on the relevance, thereby assisting improvement of efficiency in identifying the terminal type of an access source to a service.
