Problems solved by technology

One is that different evaluators have different subjective scoring standards. Maybe when two people have the same degree of approval for a movie, one person will give a score of 9, and the other will give a score of 8. For those who want to know For audiences who actually evaluate movies, vague information often leads to unsatisfactory needs

Abstract

The present invention relates to a method for emotional analysis of film reviews based on Python, including a data acquisition stage, a data preprocessing stage and a data analysis stage; the data acquisition stage uses Python to build a web crawler; the data preprocessing stage performs word segmentation and stop words The operation; the data analysis stage adopts the naive Bayesian machine learning method, combined with the sentiment dictionary method to carry out predictive analysis. Compared with other common sentiment analysis techniques, the present invention achieves the best in accuracy and recall.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a Python-based film review sentiment analysis method. Background technique [0002] Since Shannon started the research on information theory, there has never been a channel for information to have such a huge volume and speed as the Internet channel today. A large number of bits are transmitted on the highway of the network every day or stored in an intermediate site. These The largest proportion of data is undoubtedly the most important one for human beings to exchange information, that is, natural language. No matter what kind of network business, it cannot be separated from the use of natural language data, such as e-commerce websites, early blogs, multi-person interactive forums, chat rooms, and microblogs with over 100 million users. Regardless of age, region, or gender, Internet users will always use natural language data to express their support or opp...
