Abstract

The invention particularly relates to a text sentiment analysis method and system based on deep learning. The method includes: normalizing initial text data to generated preprocessed text data, and clustering the preprocessing text data to preset fields; manually labeling part of data in different fields, training a sentiment analysis model based on the deep learning, and building the special depth of each preset field; using a formed classifier and the special depths to perform sentiment classification on to-be-classified text. The method has the advantages that manpower cost is reduced, influence of feature engineering on classification results is avoided, and workload of special engineering is reduced at the same time; in addition, the fields where the text belongs to are considered, sothat the accuracy of text sentiment analysis is increased.

Description

technical field [0001] The present invention relates to the field of natural language processing, in particular to a text sentiment analysis method and system based on deep learning. Background technique [0002] In the Web 2.0 era, every netizen has become a source of information on the Internet. Information release platforms for various purposes emerged as the times require, such as FaceBook, Xiaonei, Sina Weibo, etc., for users to publish, obtain, and share various information. Due to the large number of Internet users, the average amount of information generated by each information release platform every day is also large, so the amount of information generated by the Internet every day is also huge. Sentiment analysis, also known as emotion mining and opinion mining, is the process of processing, analyzing, summarizing, and inferring texts to obtain the emotional color of the text. It is also very difficult. [0003] In terms of text sentiment analysis, foreign schol...
