1. A computer-readable, non-transitory medium storing therein a program for calculating similarity causing a computer to execute a process comprising:

  • first counting a matching-attribute-value count by comparing, across a plurality of databases that store configuration items belonging to an information system, attribute values of one configuration item in each of the databases, the matching-attribute-value count being number of attribute values that are identical to each other;

    second counting a matching-attribute-value count by comparing, across the plurality of databases, attribute values of a configuration item that has a predetermined relationship with the one configuration item in each of the databases; and

    calculating similarity between the configuration items, of which matching-attribute-value counts each have been counted at any one of the first counting and the second counting, based on the matching-attribute-value count counted at the first counting and the matching-attribute-value count counted at the second counting.
