Among all the data processed by associated rules in this article, part of them is time data and it is also the key point of the analysis.To facilitate the concept hierarchy of the time data, this research brings out the (0, 1) standardized technology for time data normalization and use it to convert time data to numeric data skillfully.Then in the process of time data generalization, this research presets threshold value according to the data attributes, digging task requirement and other actual situation, also applies histogram analytical method of concept hierarchy technology to fine tuning on preset threshold value, then brings out histogram threshold fine tuning technology.
