Problems solved by technology

[0003] Traditional sentiment lexicons are limited in the number of emotional words, and have no emotional category labels and no emotional intensity value labels, which greatly affect the expression of text emotional features in terms of quantity and quality; classification algorithms are also faced with long training time and low accuracy. troubled

Embodiment Construction

[0046] A sentiment lexicon establishment and sentiment calculation method, comprising the following steps:

[0047] (1) Obtain emotional word information:

[0048] Analyze the Chinese emotional corpus Ren-CECps, and extract emotional word information from the Chinese emotional corpus Ren-CECps;

[0049] The Chinese emotional corpus Ren-CECps is composed of paragraphs and texts marked with artificial emotional features. All texts are part-of-speech tagged and saved in XML format;

[0050] Emotion word information includes: emotion vocabulary ontology, denoted as n>0; the emotional category to which the emotional word belongs, denoted as There are eight types of emotional categories to which emotional words belong, 1≤j≤8; the emotional intensity value under the corresponding emotional category is recorded as E intensity , 0.0≤E intensity ≤1.0;

[0051] There are eight types of emotion categories, including: joy, recorded as hate hate, recorded as love love, record as ...

Abstract

The invention discloses an emotion dictionary building and emotion calculation method. A high-quality artificial marking Chinese language database Ren-CECps is used as an initial seed emotion word; under the combination of Chinese thesauruses and internet Chinese text languages (non-marked), emotion synonyms are expanded, and a kernel function method is used on the emotion calculation method; therefore, the problems of long training time and low accuracy of an emotion calculation process are solved.

Description

technical field [0001] The invention relates to the field of emotion calculation and text emotion analysis method, in particular to an emotion dictionary establishment and emotion calculation method. Background technique [0002] In the field of text sentiment computing, sentiment words are often used as text feature words, and the quantity and quality of sentiment words seriously affect the representation quality of text sentiment features. General text sentiment feature words mostly use adjectives, adverbs and a small number of nouns in the text segment as feature words; conventional sentiment calculation methods mostly use SVM (Support Vector Machine) and Naive Bayesian methods. [0003] Traditional sentiment lexicons are limited in the number of emotional words, and have no emotional category labels and no emotional intensity value labels, which greatly affect the expression of text emotional features in terms of quantity and quality; classification algorithms are also f...
