Embodiment Construction
[0117] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0118] The knowledge map is generally composed of concepts (for example, "person"), entities (for example, "Zhang San"), the category relationship between entities and concepts (for example, "Zhang San" belongs to "person"), and the relationship between concepts and concepts. Subclass relationships between (for example, "movie actor" is a subclass of "actor"), relationship between entities (for example, "Zhang San"'s mother is "Li Si"), attributes ...

This application discloses a necessary attribute determination method, related equipment, and a readable storage medium. The virtual concept composed of all entities with attributes to be determined in the knowledge map is regarded as an ideal concept of the attribute to be determined, and the attribute to be determined is an ideal concept. Necessary attribute, the closer the concept to be determined in the knowledge graph is to the ideal concept of the attribute to be determined, the greater the probability that the attribute to be determined is a necessary attribute of the concept to be determined. Based on the above scheme, according to the characteristics of the ideal concept of the attribute to be determined and the characteristics of the concept to be determined, the closeness of the concept to be determined to the ideal concept of the attribute to be determined can be determined, and then whether the attribute to be determined is a necessary attribute of the concept to be determined . Based on the above solution, it is possible to determine whether an attribute is a necessary attribute of a certain concept, and compared with manual determination, it can save manpower and time, thereby improving the efficiency of determination.
Description
technical field [0001] The present application relates to the technical field of knowledge graph, and more specifically, relates to a necessary attribute determination method, related equipment and a readable storage medium. Background technique [0002] With the continuous development and progress of artificial intelligence, knowledge graph (Knowledge Graph) is widely used in information retrieval, question answering, recommendation system and machine translation and other fields. The service quality that knowledge graph can provide depends largely on the quality of knowledge graph. As one of the evaluation criteria for the quality of knowledge graphs, the integrity of knowledge graphs has attracted extensive attention from those skilled in the art. [0003] In the knowledge graph, if an entity lacks a certain attribute, it will affect the service quality of the knowledge graph, and this attribute can be called a necessary attribute of the entity. For example, in the knowl...
