Embodiment Construction

[0070] In order to facilitate understanding, some typical multi-round dialog state tracking schemes in the prior art are firstly introduced.

[0071] Such as figure 1 Shown is a schematic diagram of the running process of a multi-round dialog state tracking solution in the prior art. This scheme is a scheme based on Question&Answering (QA) knowledge base reasoning, and its specific operation process is as follows:

[0072] First of all, according to the current multiple rounds of dialogue and the current input, determine the keywords of the multiple rounds of dialogue, as the input of the current dialogue state, and then search in the knowledge base according to the predefined rules. This step is as follows: figure 1 Shown in box 101.

[0073] Then, after retrieval, the corresponding set of candidate multi-round dialogues can be obtained, such as figure 1 Shown in box 102.

[0074] Finally, according to the pre-defined similarity calculation rules, the similarity between t...

Abstract

The invention is suitable for the technical field of artificial intelligence, and provides a voice interaction method and device and terminal equipment, and the method comprises the steps of obtaininghistorical dialogue data when a to-be-replied user statement is received; identifying target entity information in the user statement, and identifying historical entity information in the historicaldialogue data; extracting key entity information associated with the user statement from the historical entity information; generating a target interaction statement according to the target entity information and the key entity information; and outputting a reply statement corresponding to the target interaction statement. By adopting the method, the accuracy of dialogue state tracking and user intention recognition can be improved, the natural language processing capacity of the dialogue system is improved, and the reply rationality of the dialogue system in the multi-round dialogue process is enhanced.

Description

technical field [0001] The present application belongs to the technical field of artificial intelligence, and in particular relates to a voice interaction method, device and terminal equipment. Background technique [0002] Natural Language Processing (Natural Language Processing, NLP) is an important part of Artificial Intelligence (AI), and its typical application scenarios include task-oriented dialogue systems and machine translation. In a multi-round dialogue scenario based on natural language dialogue, how to track and determine the user's intention is a crucial link. In the process of Dialogue State Tracking (DST), it is necessary to dynamically adjust the model in combination with historical dialogues to extract key information contained in user sentences, then determine user intentions, and complete corresponding responses in combination with the dialogue system. [0003] In the prior art, the DST method based on machine learning requires the model to well understa...
