Abstract: A method, apparatus, device, and storage medium for linking an entity, relates to the technical fields of knowledge graph and deep learning are provided. The method may include: acquiring a target text; determining at least one entity mention included in the target text and a candidate entity corresponding to each entity mention; determining an embedding vector of each candidate entity based on the each candidate entity and a preset entity embedding vector determination model; determining context semantic information of the target text based on the target text and each embedding vector; determining type information of the at least one entity mention; and determining an entity linking result of the at least one entity mention, based on the each embedding vector, the context semantic information, and each type information.

Abstract: A theme classification method based on multimodality is related to a field of a knowledge map. The method includes obtaining text information and non-text information of an object to be classified. The non-text information includes at least one of visual information and audio information. The method also includes determining an entity set of the text information based on a pre-established knowledge base, and then extracting a text feature of the object based on the text information and the entity set. The method also includes determining a theme classification of the object based on the text feature and a non-text feature of the object.

Abstract: A method and an apparatus for generating a text topic and an electronic device are disclosed. The method includes: obtaining entities included in a text to be processed by mining the entities; determining each candidate entity in a knowledge graph corresponding to each entity included in the text to be processed through entity links; determining a set of core entities corresponding to the text to be processed by clustering candidate entities; determining each candidate topic included in the text to be processed based on a matching degree between each keyword in the text to be processed and each reference topic in a preset topic graph; and obtaining the text topic from the set of core entities and the candidate topics based on association between each core entity and the text to be processed as well as association between each candidate topic and the text to be processed.
