Abstract

The invention discloses a comparison sequence pattern excavation method and device, and relates to data analysis technologies. The problem that a comparison sequence pattern multi-class excavation mechanism is lacked is solved. The method comprises the steps of collecting multi-class sequence sample data; calculating the frequency of a comparison sequence pattern of arising in a data set constituted by the multi-class sequence sample data; calculating the comparison degree of the comparison sequence pattern in a support degree range according to the frequency of the comparison sequence pattern of arising in the data set constituted by the multi-class sequence sample data; evacuating to obtain the comparison sequence pattern based on the multi-class sequence sample data. The comparison sequence pattern excavation method and device are applicable to data excavation analysis, and data analysis excavation at a deeper level is achieved, so that the data analysis with higher pertinence can be conducted.

Description

technical field [0001] The invention relates to data analysis technology, in particular to a method and device for mining comparative sequence patterns. Background technique [0002] As an important task of data mining, sequential pattern mining has a wide range of applications. For example: Broadcasting and TV service providers analyze users' viewing records and discover users' viewing preferences, which can provide decision support for programming. At the same time, sequential pattern mining has also attracted the attention of many researchers, and different types of sequential patterns have been proposed one after another, such as: frequent sequential patterns, closed sequential patterns, contrastive sequential patterns, periodic patterns, partial order patterns, etc. [0003] Given two types of sequence sample sets, compare the sequence pattern descriptions that are frequent in the positive sequence sample set (the support of the pattern is greater than the specified th...
