Abstract

The invention discloses an emotion detection method and system based on map expressions. The method includes collecting text data with map expressions, preprocessing the collected data, and convertinginto a word vector data set; and inputting a data set generated by a data preprocessing unit into a trained network model, the network model outputting a corresponding emotion detection result. The emotion detection method based on map expressions can realize emotion detection of user comments and the like; further, a multiple neural network and an attention mechanism are combined, thereby improving the identification degree of map expressions related with various emotions; the model is trained through an iterator, thereby saving internal storage; and through transfer learning, parameters that can be trained are gradually unfrozen, the risk of over-fitting after transfer learning is reduced as much as possible, and the characteristics of a pre-training model are fully kept.

Description

technical field [0001] The invention relates to the field of emotion analysis, in particular to an emotion detection method and system based on emoticon stickers. Background technique [0002] With the continuous development of the network and the rapid growth of social platforms, the Internet is flooded with a large amount of unstructured text data, which contains a lot of valuable information that cannot be easily processed and extracted. Therefore, if it is possible to automatically extract emotions from data such as Weibo and comments, it can be applied to positive and negative word-of-mouth monitoring of products or services, thereby improving product functions or service processes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an emotion detection method and system based on emoticon stickers for the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention...
