Intelligent data matching method in medicine flow direction data cleaning

The invention discloses an intelligent data matching method in medicine flow direction data cleaning and relates to the field of data matching of data cleaning in big data. The data intelligent matching method in medicine flow direction data cleaning comprises a data collection module, wherein the data collection module is used for collecting data in a system of each subsection, a common substring algorithm is used for retrieving the same character substring and the common character substring in the data to generate a regular expression, and if matching succeeds, the data collection module is used for collecting the data in the system of each subsection; and therefore, the data can be converted. According to the intelligent data matching method in medicine flow direction data cleaning, the manual processing result is learned by using an algorithm, the result is deduced, the matching rule is found, and the matching rule is used for processing other to-be-matched data, so efficiency of manually processing the m
