Abstract

The embodiment of the invention provides a short English movie review classification method and device, and the method comprises the steps: obtaining a feature word set of a to-be-classified short English movie review text; performing prediction classification on the feature word set through a pre-trained first-layer classification model to obtain a first prediction result set, splicing the firstprediction result set, and taking arithmetic mean to obtain a new test set; predicting the new test set through a pre-trained second-layer classification model to obtain a second prediction result set, and minimizing the second prediction result set; performing maximum normalization processing to obtain a normalized result set; and processing the normalized result set by adopting a simple majoritymethod to obtain a classification result of the to-be-classified short English movie review. According to the technical scheme of the invention, the accuracy and robustness of the classification result are greatly improved.

Description

technical field [0001] The invention relates to the field of network science and technology, in particular to a method and device for classifying short English movies. Background technique [0002] With the advent of the era of big data, the amount of online review data is increasing day by day. The massive data and the varying quality of reviews make the study of the effectiveness of film reviews more realistic. The goal of in-depth mining of film reviews is to analyze and evaluate the value embodied in film reviews. Up to now, movie reviews have developed from paper reviews to electronic reviews. At present, many movie websites provide movie reviews as a reference for watching movies. Taking movie reviews as information sources and consumers as information readers, the linguistic characteristics and semantic content of information sources have a direct impact on the judgment and behavior of information readers. [0003] The current research status mainly includes the fo...
