Abstract

The invention relates to the field of data classification, and discloses a text data classification method and device, equipment and a storage medium. The method comprises the following steps: acquiring file image data of a real estate; based on a preset OCR (Optical Character Recognition) algorithm, carrying out recognition processing on the file image data to obtain image feature data; based on the feature arrangement position of the image feature data, converting the image feature data into an N-dimensional vector to obtain an N-dimensional feature vector, N being a positive integer; reading a preset N-dimensional test node set, and calculating Euclidean distances between the N-dimensional feature vector and all N-dimensional test nodes in the N-dimensional test node set in the same N-dimensional space to obtain a measurement distance set; screening out measurement distances smaller than a preset division threshold in the measurement distance set to obtain a screened distance set; performing classification regression processing on the screening distance set according to a preset regression algorithm to obtain an image type; and determining the image type as the type of the file image data.

Description

technical field [0001] The present invention relates to the field of data classification, in particular to a text data classification method, device, equipment and storage medium. Background technique [0002] In real estate financial transactions, it involves some very important identification documents and real estate certification documents to prove and use, mainly including: ID card, real estate certificate, marriage certificate, personal credit certificate, etc., which are used in business processing and processing All kinds of data are mostly in the form of pictures and images, which are generally obtained through paper scanning or mobile terminal photographing. Some techniques for classifying types of real estate data. [0003] There are also some techniques for classifying data in the prior art, but in the process of classifying real estate data in the prior art, it is impossible to classify data with too many types, so a new technology is required. SUMMARY OF THE...
