Electric power service robot intelligent scene session method and device

Abstract

The invention discloses an electric power service robot intelligent scene session method and device based on natural language understanding, and the method comprises the steps: enabling an electric power service robot to carry out the recognition of a user intention based on text information inputted by a user, and build a session flow according to a recognition result; performing text entity extraction processing on the text information in the session process to obtain entity information; performing expression analysis on the text information in the session process to obtain an expression analysis result; selecting a session node in the session process based on the entity information and the expression analysis result, and performing context combination updating processing on the text information by using a natural language understanding model based on the session node to obtain a context combination updating result; and performing context node skip processing according to the contextin combination with the update result, and performing scene session reply based on the context node skip processing result. In the embodiment of the invention, barrier-free communication with the user in multiple rounds of interaction can be realized, and the user interaction experience is improved.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a method and device for an intelligent scene conversation of a power service robot based on natural language understanding. Background technique [0002] Natural Language Processing (NLP, Natural Language Processing) is a technology that uses natural language to communicate with computers, because the key to processing natural language is to let computers "understand" natural language, so natural language processing is also called natural language understanding (NLU, Natural Language Understanding), also known as Computational Linguistics. On the one hand, it is a branch of language information processing, on the other hand, it is one of the core topics of artificial intelligence (AI, Artificial Intelligence). [0003] Existing smart scene conversation technologies for power service robots are all based on natural language understanding FAQ dialogue technology...

AI Technical Summary

Problems solved by technology

[0003] Existing smart scene conversation technologies for power service robots are all based on natural language understanding FAQ dialogue technology, which is based on user questions, processed with natural language understanding technology, and returns answers to users after matching user intentions; but based on natural language understanding The FAQ dialogue technology of the company is limited to the form of one question and one answer, without the ability of context association. Although natural language processing technology can be applied to it, it still cannot give users a natural dialogue experience.
