Problems solved by technology

[0004] However, the existing calculation method of movie expectation value is mainly carried out in the form of questionnaire survey. This method needs to design a questionnaire, then organize the respondents to answer the questionnaire, and then calculate the movie expectation value according to the statistical questionnaire results. This method will inevitably cause additional The labor cost is low, the work efficiency is low, and because the surveyed population is relatively concentrated, it is not representative. In the movie information database established based on this method, the index of movie expectation value is often not in line with the actual situation.

Abstract

The invention provides a method and a system for calculating movie expectation. The method includes: collecting comments on upcoming movies from microblogs, and marking manually to obtain training samples, using machine learning to train a maximum entropy classifier with the obtained marked samples so as to finish automatic classification of the comments on the upcoming movies, and calculating according to classification results of a movie to obtain the expectation on the movie. The invention further discloses a system for calculating the movie expectation. The method and the system are simple, practical, and time-saving and labor-saving, and calculating results of the movie expectation are real and reliable.

Description

technical field [0001] The invention belongs to the technical field of natural language processing, and in particular relates to a calculation method and system for movie expectation value. Background technique [0002] At present, people are more and more accustomed to expressing their opinions and emotions on the Internet. There are a large number of texts with emotional tendencies on the Internet, and these texts often exist in the form of product reviews, forum reviews, or blogs. In order to automatically acquire and analyze such subjective information, the research on text sentiment analysis (Sentiment Analysis) has been developed rapidly and has been closely watched by the academic and commercial circles. [0003] As we all know, the establishment of a movie information database is extremely important for people to understand and search for a large number of movie information. The movie information usually includes the movie director, main actors, investment situatio...
