Abstract
There is a certain similarity of the characteristic vectors of the comment statements between the comments between the commentary emotion category, bringing certain difficulties to text emotion 3 classification. This article proposes a specification of the specification. It is mainly from 8 aspects of fresh products to 8 aspects (emotional adjustment words + feature words). Add all kinds of representatives selected to a word-defined dictionary, by changing the word words in the comment statement, in turn increases the difference between the comment statement feature vector between the category during the quantization process, thereby enabling classification Easy to identify the emotional polarity of comment statements. After verification, this method achieved a good classification effect, the correct rate reached 86.14%, the recall rate reached 84.97%, which increased 4.24% and 4.42% compared to the method without dictionary.
