Abstract

The invention provides an intelligent analysis method and a device for insurance industry documents. The method comprises the steps of converting original data in a PDF format into data in a CSV format, wherein the data in the CSV format comprises a predetermined document text recognition feature dimension; performing data cleaning processing on the converted data in the CSV format; capturing context semantic information of the text features based on the text positions, and expanding feature dimensions; labeling a training sample to be used as a training sample by utilizing a plurality of categories to obtain a training sample set, wherein the plurality of categories comprise text contents and a plurality of title categories of different levels; selecting a training set from the training sample set, training a random forest algorithm by using the training set, and performing category classification on the test sample by using the trained random forest algorithm to obtain a category classification result of test sample data features; and recombining the document content based on a category classification result, generating a structured file for outputting, and extracting important attributes in the document.

Description

technical field [0001] The invention relates to the technical field of document analysis, in particular to an intelligent analysis method and device for documents in the insurance industry. Background technique [0002] In the 1990s, with the rapid development of artificial intelligence technology, many foreign intelligence workers applied the concept of machine learning to the field of automatic text classification. With the continuous maturity of machine learning algorithms, more and more electronic documents can be intelligently parsed and classified. However, in the field of text data in today's society, the vast majority of text exists in unstructured form. Only structured data can be used for better training and prediction of machine learning. Therefore, structural analysis of text data is a major problem in the field of natural language processing today. [0003] The existing document storage format is basically in PDF format, so it is generally necessary to conver...
