Abstract

The invention relates to a dialogue sentiment analysis method based on an interactive long-short-term memory network, which is characterized by comprising the following steps of: constructing a dialogue sentiment corpus set; preprocessing the dialogues in the dialogue emotion corpus set; defining interaction in the dialogue sentiment analysis scene, summarizing three characteristics including semantic comprehension, credibility and influence contained in the interaction, and adopting corresponding calculation methods for different characteristics; respectively fusing the calculated semantic vector ui, credibility cred (u) and influence R of each statement into an LSTM structure, so that the LSTM structure can model interaction between talkers in a conversation, and is called as an interactive long short-term memory network Interactivity-LSTM; and carrying out model training.

Description

technical field [0001] The invention relates to the technical field of dialogue emotion classification, in particular to a text dialogue emotion analysis method. Background technique [0002] With the rapid development of the Internet and social networks, more and more users rely on instant messaging software such as WeChat, QQ, and DingTalk, which have become the main channels for people's daily communication. The Internet records a large number of chat conversations every day. These conversations are usually With a large number of evolving subjective attitudes and emotions of the talkers, dialogue sentiment analysis is becoming a new research topic, attracting the attention of both academia and industry. Its importance has been recognized by all walks of life in society, for example, it can help product manufacturers improve their products, and help the government understand the preferences of the people. Therefore, dialogue sentiment analysis not only has important theor...
