Abstract

The invention discloses a comment analyzing method and system based on a term vector and relates to the technical field of emotion analysis, natural language processing and the like. A machine is utilized to analyze the comment, automatic user comment analysis is made by using the machine, and the working efficiency is improved. The method is characterized in that user comments are collected to form a comment corpus, each comment in the comment corpus is converted into the sentence vectors with identical dimension, a plurality of comment types are set, each comment is labeled with the corresponding type according to the labels which are input manually, a classifier is trained with the sentence vectors as the input and the comment type that each sentence vector corresponds to as the output, a new comment is acquired and converted into the sentence vector, and the sentence vector that the new comment corresponds to is input into the classifier to obtain the comment type of the new comment.

Description

technical field [0001] The invention relates to the technical fields of emotion analysis, natural language processing and the like. Background technique [0002] With the continuous development of e-commerce, there are more and more user comments on a product on the Internet. By analyzing user comments, we can understand users' opinions and suggestions on products, which will help improve products and improve service quality. However, as the number of users continues to increase, the amount of corresponding comments also increases greatly. If you still rely on manual reading of comments to understand user opinions, work efficiency will be greatly reduced, and users’ opinions or suggestions on products or services cannot be understood in a timely manner. . Contents of the invention [0003] In view of the above situation, the present invention proposes a method and system for analyzing comments by using a machine, which can automatically analyze user comments with the hel...
