Chatbot technology is constantly evolving and its practical effects are becoming increasingly prominent
The technology used to build chatbots was early rule-based and keyword-driven, without the need to understand the scenarios and meanings of the input messages. With the advent of artificial intelligence, chatbots can use technologies such as natural language processing to understand language and intentions and make corrections.
Chatbot technology involves artificial intelligence such as natural language understanding (NLU), natural language generation (NLG), and speech recognition (ASR). At present, the functions of natural language understanding include technologies such as user intention recognition, user emotion recognition, anaphora resolution, omitted responses, response confirmation and rejection judgment. Natural language generation can automatically generate user-oriented natural language feedback based on the non-verbal information produced in the dialogue management section, including retrieval expressions and generative expressions.
