一种改进的基于共现关系的短文本特征扩展算法研究
Improved expansion algorithm based on co-occurrence relationship between short text feature
摘要
Abstract
In this paper, an improved expansion algorithm based on co-occurrence relationship between short text feature is proposed aimed at not ideal situation for a single co-occurrence word feature expansion. The im- provement is that we considered more than a total of the current words at the same time and improved features of the word weight calculation formula and characteristics of expansion strategy, and applied to the Chinese short-text classification, which has improved classification accuracy.关键词
