Abstract: An information processing method is disclosed. The method includes: obtaining initial feature information of to-be-queried information; performing feature processing on the initial feature information of the to-be-queried information, to obtain target feature information of the to-be-queried information, where the feature processing includes at least feature dimension processing used to process a data dimension of the initial feature information of the to-be-queried information to be a preset dimension; performing a first retrieval operation on m pieces of candidate information based on the target feature information of the to-be-queried information, to obtain a first retrieval result; and performing a second retrieval operation on the first retrieval result based on the initial feature information of the to-be-queried information, to obtain result information corresponding to the to-be-queried information. The method can quickly and efficiently implement information retrieval.
