A Chinese Text Feature Extraction Method Fused with Text Mood

Abstract

The invention discloses a Chinese text feature extracting method with a text mood fusion function. By means of the method, it is achieved that the text feature representation fusing mood features, syntax features and semanteme features is obtained in a lengthened text. The method comprises the steps that firstly, a text word set and a mood word set are constructed, the text word set and the mood word set are transformed into word embedding forms respectively, and corresponding vector models are obtained; secondly, according to the text word embedding represented time step dimensions and feature dimensions, text features are screened, the mood features are fused into the time step dimension of the selected text feature, and the text feature representation which accurately represents the semanteme is obtained. According to the method, the contributions of modal particles to the text semanteme are fully utilized to fuse the mood features, the syntax features and the semanteme features into the text feature representation, and the text feature representation is low in dimension and continuous so that the text semanteme can be better represented, and natural language processing tasks, such as text analysis, language translation and relation extraction, can be better effectively supported.

Description

technical field [0001] The invention belongs to the field of natural language processing, and relates to a Chinese text feature extraction method that integrates text mood; based on massive Chinese texts, the Chinese mood features are integrated into the text features to better represent the semantics of the Chinese text. Background technique [0002] The number of texts from the Internet, e-commerce and other fields increases sharply every day. Manual processing and understanding of these massive text data will cost a lot of money and the losses outweigh the benefits. In order to quickly and efficiently mine useful knowledge patterns in massive texts, it is a better choice to process and understand texts based on artificial intelligence related technologies; the key to intelligent analysis of massive texts is to effectively represent the semantic features of texts, the most commonly used The text representation method is the Bag of Words (BOW) model. Although the bag of wor...

[0002] The number of texts from the Internet, e-commerce and other fields increases sharply every day. It will cost a lot of money to process and understand these massive text data manually.

In order to quickly and efficiently mine useful knowledge patterns in massive texts, it is a better choice to process and understand texts based on artificial intelligence-related technologies; the key to intelligent analysis of massive texts is to effectively represent the semantic features of texts, the most commonly used The text representation method is the Bag of Words (BOW) model. Although the bag of words model is simple and practical, the text representation is often high in latitude and sparse.
