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.

Abstract: Embodiments of the present disclosure relate to a method, an apparatus and a device for constructing a data model, and a medium. The method for constructing the data model includes obtaining a first attribute set associated with an entity type. The method further includes aligning a plurality of attributes with a same semantics in the first attribute set to a same attribute, to generate a second attribute set associated with the entity type, attributes in the second attribute set having different semantics. The method further includes constructing the data model associated with the entity type based on the entity type and the second attribute set.
