Abstract

The application discloses a method and device for calculating entity similarity, and relates to cloud computing technology in the field of computer technology. In the embodiment of the present application, not only the first similarity between the first entity and the second entity is determined, wherein the first similarity is: the similarity calculated according to the feature vector of the first entity and the feature vector of the second entity; The set of edge relations of the first entity and the set of edge relations of the second entity, according to the set of edge relations of the first entity and the set of edge relations of the second entity, calculate the first layer distance between the first entity and the second entity; and then can According to the first similarity and the first-level distance, calculate the second similarity between the first entity and the second entity, because the information in the edge relationship set can better reflect the similarity between entities, so it overcomes the problem of only relying on feature vectors Calculating entity similarity is a technical problem with low accuracy, and then achieving the technical effect of calculating similarity with high accuracy.

Description

technical field [0001] The present application relates to cloud computing technology in the field of computer technology, in particular to a method and device for calculating entity similarity. Background technique [0002] There are often scattered information about an entity distributed in the network, and entity fusion is usually used when summarizing the scattered information. [0003] When performing entity fusion in the prior art, it is only judged whether the two entities can be fused into one entity based on the similarity of the feature vectors of the two entities. The entity of the feature vector is not the same entity, resulting in low accuracy of entity fusion. Contents of the invention [0004] Embodiments of the present application provide a method and device for calculating entity similarity to solve the technical problem of low accuracy in calculating entity similarity. [0005] The first aspect of the embodiment of the present application provides a meth...
