Abstract

The invention discloses a Chinese emotion new word recognition method and system in combination with user emotion expression ways.The method includes the steps that input texts are acquired; a candidate new word set is established based on character strings, with word frequencies larger than that of a first preset threshold value, in the input texts; the candidate new word set is filtered through a Chinese old word library; new words are screened out of the filtered candidate new word set based on statistical indexes, and a new word set is established, wherein the statistical indexes include word formation ability, pointwise mutual information, flexibility and adjacency entropy; based on the emotion tendency pointwise mutual information, emotion new words are recognized from the new word set, and an initial emotion new word set is established; based on the user emotion expression ways involved in the input texts, high-confidence-coefficient emotion new words are screened out of the initial emotion new word set to serve as recognized Chinese emotion new words.By means of the embodiment, the technical purpose about how to improve the precision and flexibility of emotion new word recognition is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer science and technology, and in particular, relate to a method and system for recognizing new Chinese emotional words combined with user emotional expression methods. Background technique [0002] As a basic element of the sentiment lexicon, sentiment words are the basis of most text sentiment analysis methods. With the popularization of Web2.0 technology, new words used to express emotions in social media are constantly emerging, and automatic identification of these new emotional words is of great significance for the construction of emotional lexicons and text sentiment analysis. Nowadays, massive social media texts on the Internet bring data support to the recognition of emotional new words, but also pose severe technical challenges. [0003] Previous Chinese emotional new word recognition work can be divided into two categories: one type of work recognizes new emotional words...
