Data filtering is the first step in the utilization and development of big data, that is, obtaining value data from massive data resources, building system operation database, and realizing the mining and sorting of value data. However, restricted by the infinite big data environment and limited data acquisition ability, almost no technology can obtain all the value data. In this paper, a series of indicators are proposed to evaluate and enhance the data filtering algorithm.
