Abstract

The embodiment of the invention provides a bullet screen emotion analysis method and device. The method comprises the steps of obtaining a bullet screen text in a preset time period; matching the bullet screen text with a bullet screen emotion dictionary, and performing text vectorization on emotion words obtained by matching to obtain a word vector of each emotion word; summing word vectors of all emotion words in the bullet screen text to obtain a bullet screen text vector, and inputting the bullet screen text vector into a preset emotion analysis model to obtain an emotion type of the bullet text; wherein the preset emotion analysis model is obtained after training according to a bullet screen text sample with an emotion type label; and performing text vectorization on the emotion wordsobtained by matching to obtain a word vector of each sentiment word, thereby realizing quantification of the sentiment words, and inputting the barrage text vector into a preset emotion analysis model to obtain an emotion type of the bullet screen text, so that the emotion type of the bullet screen text can be quickly and accurately obtained.

Description

technical field [0001] The invention relates to the field of text information processing, in particular to a barrage sentiment analysis method and device.
