Abstract

The invention discloses a method for screening and classifying data objects. The method comprises the following steps: reading a screening request, and establishing a hierarchical attribute description network according to a descriptor value; extracting a descriptor value in the contained attribute description network from description information of to-be-screened data objects; establishing a mapping relation between the screening request and the attribute description network, and generating a path dependence graph; performing traverse comparison on the descriptor value contained in the description information of to-be-screened data objects and each descriptor value in the path dependence graph; recording the described path as a matching path of the to-be-screened data object if all descriptor values in a description path are contained in the description information of to-be-screened data objects; determining screening requirements met by the to-be-screened data objects according to each matching path of the to-be-screened data objects. According to the method for screening and classifying data objects, a common descriptor value and a common description subpath are merged based on the path dependence graph, judgment in the screening process is reduced, and the calculation time is saved.

Description

technical field [0001] The present application relates to data screening technology, in particular to a method for screening and classifying data objects. The present application also relates to a device for screening and classifying data objects, and an electronic device. Background technique [0002] With the development of cloud computing and big data, various computing models have emerged in the field of big data computing for processing and computing in various data computing scenarios; among them, screening from massive data The application scope of the data calculation scenario of producing some useful data is becoming wider and wider, especially in the form of filtering out the targets that meet each screening requirement in the large-batch screening requirement from massive user data based on the bulk screening requirement of one-time input user group. [0003] Existing solutions are implemented through the Map-Reduce framework program, which is a software archite...
