Inference rule automatic discovery method and system, database and search method

摘要

The present disclosure provides methods and systems for automatic inference rule discovery, medical knowledge databases and search methods. The inference rule automatic discovery method includes acquiring each relation matrix of the medical relations. The relation matrix reflects the relation between the vectors of the medical entities having the medical relation. However, medical knowledge is a combination of two medical entities and one medical relationship, each. The inference rule automatic discovery method includes acquiring an inference rule based on a plurality of the medical-related relational matrices. The inference rules acquired each include a first medical relationship, a second medical relationship, and a third medical relationship. The inference rule is used to show that the third medical relationship can be inferred from the first medical relationship and the second medical relationship. According to the methods and systems of the present disclosure, inference rules based on medical knowledge can be automatically constructed, and no artificial definition is required, which saves time and effort and reduces time costs. Search becomes convenient. [Selection diagram]
