Abstract:
1. An information-processing apparatus, comprising: an operation information storage portion that stores at least two pieces of operation information, the at least two pieces of operation information comprising a user identifier for identifying a user and at least one object identifier for identifying at least one object on which the user has performed an operation; a link information-generating portion that reads the at least two pieces of operation information from the operation information storage portion, detects at least two object identifiers for identifying at least two objects, which are linked via the user identifier contained in the at least two pieces of operation information, and generates link information, which is information indicating a link relationship between the at least two objects and a level of the link relationship between the at least two objects; an object identifier-accepting portion that accepts an object identifier; an in-group object identifier-acquiring portion that acquires at least two object identifiers having at least a predetermined level of relevance with the object identifier accepted by the object identifier-accepting portion, using the link information generated by the link information-generating portion; and an in-group object information output portion that outputs object information, which is information related to the at least two object identifiers acquired by the in-group object identifier-acquiring portion, or information related to an object identified with the at least two object identifiers acquired by the in-group object identifier-acquiring portion, wherein the link information-generating portion creates a unipartite graph using the at least two object identifiers by eliminating the user identifier from a bipartite graph comprising the at least two object identifiers and the user identifier, wherein the in-group object identifier-acquiring portion acquires the at least one object identifier being directly linked with the object identifier accepted by the object identifier-accepting portion, and wherein the in-group object identifier-acquiring portion uses link levels to additionally acquire another at least one object identifier that is directly linked with the at least one object identifier directly linked with the object identifier accepted by the object identifier-accepting portion.
