Embodiment 1

[0052] figure 1 It is a flowchart of a method for analyzing the semantic orientation of comment texts on Chinese Internet topics provided by Embodiment 1 of the present invention. This embodiment is applicable to analyzing the semantic orientation of comment texts in Chinese Internet topics, and the method can be executed by a computer , including the following steps:

[0053] Step 110, perform word segmentation and sentence segmentation on the Chinese network topic comment text, and obtain a result sequence.

[0054] The most basic units of Chinese network topic comment text are words and sentences. Therefore, firstly, word segmentation and sentence segmentation are performed on the comment text, and the result sequence after word segmentation and sentence segmentation is obtained. In the result sequence, each sentence after the sentence clause of the comment text has been separated, and each word in each sentence is separated by a space.

[0055] Step 120, perform syntacti...

Embodiment 2

[0102] Figure 5 It is a schematic diagram of a device for analyzing the semantic tendency of a Chinese network topic comment text provided in Embodiment 2 of the present invention, such as Figure 5 As shown, the device for analyzing the semantic orientation of text network topic comments provided in this embodiment includes: word segmentation module 510, evaluation object extraction module 520, sentence pattern analysis module 530, emotional phrase extraction module 540, and sentence emotional orientation calculation module 550 And text sentiment tendency calculation module 560.

[0103] Wherein, the word segmentation and sentence segmentation module 510 is used to carry out word segmentation and sentence segmentation to the Chinese network topic comment text, and obtain the result sequence;

[0104] The evaluation object extraction module 520 is used to perform syntactic analysis and grammatical analysis on the result sequence to obtain evaluation objects;

Abstract

The invention discloses a method and device for analyzing the semantic orientation of a Chinese network topic comment text. The method comprises the following steps: performing word segmentation and sentence segmentation on the Chinese network topic comment text to obtain a result sequence; performing syntactic analysis and grammatical analysis on the result sequence to obtain an evaluation object; performing sentence pattern analysis on the result sequence to determine simple sentences and complex sentences in the comment text, judging the relations among all the simple sentences forming a complex sentence, and determining a first emotion orientation value of sentence pattern analysis; extracting emotion phrases in each sentence in the result sequence according to the evaluation object and a preset phrase matching mode, and calculating a second emotion orientation value of each emotion phrase; calculating a third emotion orientation value of each sentence in the comment text according to the first emotion orientation value and the second emotion orientation values; determining a text emotion orientation value of the comment text according to the third emotion orientation values. According to the method, the accuracy and the recall rate of the semantic orientation analysis of the network topic comment text are improved.

Description

technical field [0001] Embodiments of the present invention relate to natural language processing technology, and in particular to a method and device for analyzing semantic tendency of Chinese network topic comment text. Background technique [0002] With the rapid development of the Internet, the amount of information on various articles and speeches on the Internet is increasing, making the analysis of text orientation gradually become a hot research topic in recent years. At present, there are several main research directions in this field, among which opinion extraction and lexical orientation classification are the core technologies of orientation analysis, and text orientation classification and subjective and objective classification are also important branches of orientation analysis research directions. The research ideas in sentiment analysis are mainly machine learning methods, semantic-based methods and methods combining semantics and machine learning. [0003]...
