DATA ENTITY RECOGNITION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2023/201791

A1

Disclosed in the present invention are a data entity recognition method and apparatus, and a computer device and a storage medium. The method comprises: constructing a data set by means of a relationship mode and an attribute of data; performing conjunction on predicates in the data set, and establishing a matching rule according to the conjunctive predicates and the relationship mode of the data; on the basis of the matching rule, generating a query plan by using MQO technology; and performing matching calculation on an entity data set by using the query plan. Extended matching dependencies (MRLs) are provided in the present invention as a rule model for entity resolution, and a parallel entity resolution (PER) algorithm suitable for MRLs is also provided, that is, the MRLs are used as a matching rule, so as to achieve high accuracy and interpretability; moreover, HyperCube and MQO methods are combined to reduce the communication and calculation costs. In addition, a special data structure of a matching algorithm is further designed in the present invention, so as to accelerate the execution of the algorithm and reduce the memory occupation.
