Method and device for conducting multi-round conversation based on topic keyword guidance

Abstract

The embodiment of the invention discloses a method and a device for conducting multi-round dialogue based on topic keyword guidance, which relate to the technical field of natural language processing,and can enable the machine side to output richer, more diverse and more interesting replies to increase the number of conversation turns. A main technical proposal of that embodiment of the inventionis as follow: when the operation of initiating the current round of dialogue is detected, the current sentence input by the user being obtained; a round of dialogue referring to a chat dialogue between the user and the machine; acquiring a history statement corresponding to the current round of dialogues, wherein the history statement refers to a chat conversation between the user and the machinebefore the current round of dialogues; acquiring a history topic keyword corresponding to the history statement; a preset reinforcement learning model being used to process the current statement, thehistorical statement and the historical topic keywords, and output a reply statement corresponding to the current statement. The embodiment of the invention is mainly applied to process dynamic man-machine multi-round dialogue.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of natural language processing, and in particular to a method and device for multi-round dialogue guided by topic keywords. Background technique [0002] In recent years, with the continuous development of artificial intelligence technology, human-machine dialogue is no longer limited to specific scenarios, such as interactive question and answer, interactive recommendation, task-oriented dialogue, etc. In specific fields, such as flight booking system, scenic spot navigation system, etc., it can also realize multiple rounds of chats between humans and machines in open fields, such as conversations with chat robots. [0003] At present, the implementation scheme for human-machine multi-round dialogue is to introduce topic keywords deployed according to preset strategies in a single round of dialogue, so as to guide the machine to interact with humans in natural language. However, a...

Problems solved by technology

However, as the number of man-machine dialogue rounds increases, the chat topic will also evolve dynamically. Therefore, as the number of dialogue rounds is accumulated more and more, for the machine side, if only relying on pre-deployed topic keywords , in the process of dynamic multi-round dialogue, it will be more and more difficult to predict the topic of the next round of dialogue in a timely and accurate manner. At this time, the reply sentence output by the machine will deviate from the topic content of this round of dialogue. Output reply sentences and repeat the user's current sentence, or give common reply words one after another, such as "ummm", "ok", "haha", etc., which will make the chat between human and machine no longer possible
