Abstract:Based on the 95598 business, a unified identity recognition model is constructed by using big data analysis and text mining to effectively identify the corresponding relationship between customer phone number and account number. Using participle technique, efficient parsing address information, customer name, address and calculate the similarity score, name similarity scores, check the corresponding relationships and identify the key factor of the suspected door number indicator. According to the obtained correspondence, the weight division model is built, the matching score of corresponding relation is calculated, and the reliability of corresponding relation is verified according to the score value. KNN model was built based on the similarity score of text to calculate the matching score of corresponding relation, and identify the suspected account number according to the score value.
