Abstract
An information determining method includes: acquiring a feature vector of a target multimedia resource and feature vectors of multiple candidate multimedia resources; selecting, from the multiple candidate multimedia resources, a reference multimedia resource whose feature vector corresponds to the feature vector of the target multimedia resource; and selecting information corresponding to the target multimedia resource from multiple pieces of information about the reference multimedia resource according to the multiple pieces of information, and determining the selected information as information about the target multimedia resource.
Claims20
An information determining method, comprising:
- acquiring a feature vector of a target multimedia resource and feature vectors of multiple candidate multimedia resources;
- selecting, from the multiple candidate multimedia resources, a reference multimedia resource whose feature vector corresponds to the feature vector of the target multimedia resource;
- and selecting information corresponding to the target multimedia resource from multiple pieces of information about the reference multimedia resource according to the multiple pieces of information, comprising:
- acquiring a matching degree between each of the multiple pieces of information about the reference multimedia resource and the target multimedia resource according to the multiple pieces of information, the matching degree determined by an adjustable parameter representing a length of the target multimedia resource, the length of the target multimedia resource being inversely proportional to the matching degree;
- and selecting the information about the target multimedia resource from the multiple pieces of information according to the matching degree between the each piece of information and the target multimedia resource;
- and determining the selected information as information about the target multimedia resource.
