Title: DATA QUERY METHOD, DATA QUERY SYSTEM DETERMINING METHOD, APPARATUS
Abstract:
A data query method, a data query system determining method, and an apparatus. The method comprises: first, receiving a query request (401); then, determining E pieces of first subdata in an fth modality according to to-be-queried data in the fth modality (402); further, determining E characteristic vectors in the fth modality in a one-to-one correspondence with the E pieces of first subdata in the fth modality (403); further, determining E digital signals in the fth modality in a one-to-one correspondence with the E characteristic vectors in the fth modality (404); and finally, obtaining, in a storage system, an eth abstract semantic description corresponding to an eth digital signal in the fth modality (405). An index of the storage system is the eth digital signal in the fth modality, and accordingly, the storage system can be retrieved directly according to a digital signal of to-be-queried data, so as to obtain an abstract semantic description corresponding to the digital signal, thereby effectively reducing the time required by the retrieval, and better satisfying real-time requirements.
