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.

Abstract: The method includes: forwarding, based on path sets of nodes in a network, service data between a source node and a sink node in the network, where the path sets of the nodes in the network are determined by iteratively performing the following path set determining step: for each link in the network, obtaining a path set of a start node of the link, and determining N shortest paths from an end node of the link to the sink node; and for each path included in the path set of the start node, determining, according to the N shortest paths, the path, and the link, to add a new path formed by the path and the link into a path set of the end node.
