PROBLEM TO BE SOLVED: To provide a retrieval system capable of retrieving a signal group similar to a signal group including a plurality of signals with a simple configuration.SOLUTION: The retrieval system 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 including a plurality of signals. A second signal group including a plurality of signals is stored in the storage unit 9. The first similarity calculation unit 11 calculates the similarity between the signals included in the first signal group and the signals included in the second signal group with respect to the plurality of signals included in the first signal group. The second similarity calculation unit 12 calculates the similarity between the first signal group and the second signal group on the basis of a plurality of similarities calculated by the first similarity calculation unit 11.SELECTED DRAWING: Figure 1
【課題】複数の信号を含む信号群に類似する信号群を簡単な構成によって検索できる検索システムを提供する。【解決手段】検索システムは、読込部10、記憶部9、第1類似度算出部11及び第2類似度算出部12を備える。読込部10は、複数の信号を含む第1信号群を読み込む。記憶部9に、複数の信号を含む第2信号群が記憶される。第1類似度算出部11は、第1信号群に含まれる信号と第2信号群に含まれる信号との類似度を、第1信号群に含まれる複数の信号について算出する。第2類似度算出部12は、第1類似度算出部11によって算出された複数の類似度に基づいて、第1信号群と第2信号群との類似度を算出する。【選択図】図1
