摘要： Embodiments of the present disclosure provide a method for processing a sematic description of a text entity, and relates to the technical field of knowledge maps, and the method includes: acquiring (101) a plurality of target texts containing a main entity, and extracting related entities describing the main entity from each target text; acquiring (102) a sub-relation vector of a pair of the main entity and each related entity in each target text; calculating (103) a similarity distance of the main entity between different target texts based on the sub-relation vector; and determining (104) a semantic similarity of the main entity descripted in different target texts based on the similarity distance. Therefore, by determining the semantic similarity of the entity description in the different texts, the similarity of descriptions of the same entity in different texts may be accurately acquired.
