Abstract

The invention discloses an emotion analysis method which aims at network microblogs. The emotion analysis method which aims at the problem that in the traditional emotion analysis, expression of diversification emotion of emergencies is not enough is based on a multi-dimensional vector representation model. The emotion analysis method comprises extracting emotional words in combination with a clinical psychological emotion detection table and initializing emotion analysis vectors; automatically finding the network new words in the microblogs through a method which is based on large-scale corpuses and statistics, automatically absorbing the network new words and emotional identifiers which can express emotion, continuously expanding the emotion vectors and setting a gradational structure of the emotion vectors; performing multi-dimensional emotion analysis and timing sequence analysis on the microblogs based on an existing vector model.
