Embodiment Construction

[0015] The inventive method comprises the following steps:

[0016] Step 1: Use the corpus that has been subjected to word segmentation processing. These corpora are generally subjective comments. Sort the adjectives that appear in order of frequency from high to low, and extract the top 5%~10% of adjectives that have a certain emotional polarity. According to HowNet (Hownet) mark its emotional polarity as a seed word to form an emotional lexicon;

[0017] Step 2: Break sentences according to punctuation marks to generate short sentences one by one;

[0018] Step 3: Scan short sentences one by one to extract adjectives. Build two temporary lists for storing adjectives of the two sentiment polarities. For the adjective, judge whether it has a negative word modification, and if so, reverse the polarity and store it in the corresponding temporary list; then judge whether the short sentence starts with a transition word, if so, reverse the polarity and store it in the correspond...

Abstract

The invention discloses an establishment method of an emotion dictionary based on linguistic data, and the establishment method comprises the following steps of: in advance acquiring partial known emotional tendency adjectives, including positive and negative adjectives, extracting and analyzing the unknown emotional tendency adjectives by using adversatives and privatives, constantly extending seed lexicons and finally judging them. The method doesn't need manual intervention and belongs to a non-supervision learning method so as to greatly improve the operating efficiency. The emotion dictionary established by the method can be applied for critical analysis so as to quickly obtain emotional tendency, thereby achieving the purpose of rapid analysis.

Description

technical field [0001] The invention belongs to artificial intelligence invention technology, and specifically relates to a method for constructing an emotional dictionary based on corpus. Background technique [0002] Some of the existing Chinese emotional dictionaries are constructed by artificially summarizing some commonly used adjectives, which is inefficient and non-territorial. However, Chinese does not have a dictionary similar to English wordnet, and it is impossible to construct a dictionary of emotional words through existing dictionaries. The corpus-based sentiment dictionary construction method applies people's language habits to the analysis of texts, and constructs two types of dictionaries, positive and negative. That is to say, labor cost is saved, and it also has the ability to judge the emotion of new words. [0003] Hazivassiloglou and McKeown were the first to analyze the corpus and construct the sentiment lexicon according to the language rules. They ...
