SEARCH SYSTEM

摘要

Provided is a search system that comprises a reading unit (10), a storage unit (9), a first similarity calculation unit (11) and a second similarity calculation unit (12). The reading unit (10) reads a first signal group, which includes a plurality of signals. A second signal group, which includes a plurality of signals, is stored in the storage unit (9). The first similarity calculation unit (11) calculates, for the plurality of signals included in the first signal group, the degree of similarity between a signal included in the first signal group and a signal included in the second signal group. The second similarity calculation unit (12) calculates the degree of similarity between the first signal group and the second signal group, on the basis of the plurality of degrees of similarity calculated by the first similarity calculation unit (11).
