Embodiment Construction

[0038] Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0039] In addition, it should be understood that the term "and / or" in this article is only an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B may mean: A exists alone, and A exists at the same time. and B, there are three cases of B alone. In addition, the character " / " in this article g...

Abstract

The present disclosure discloses a negative reply recognition model acquisition method and a negative reply recognition method and device, which relate to artificial intelligence fields such as natural language processing, deep learning, and intelligent speech, wherein the negative reply recognition model acquisition method may include: obtaining through pre-training Semantic representation model; use the obtained weakly supervised corpus to train the semantic representation model to obtain the first recognition model; use the obtained supervised corpus to train the first recognition model to obtain the second recognition model; use the second recognition model as The required negative reply recognition model, in order to use the negative reply recognition model to carry out negative reply recognition on the replies to be processed. Applying the scheme described in the present disclosure can improve the accuracy of recognition results and the recall rate of negative responses, etc.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to methods and devices for obtaining negative reply recognition models and negative reply recognition in the fields of natural language processing, deep learning, and intelligent speech. Background technique [0002] Negative reply recognition technology in gossip is a method to effectively intervene in bad dialogue replies generated by open-domain dialogue systems. [0003] The current dialogue systems are mainly divided into two types: retrieval type and generation type. Among them, the retrieval method needs to build a large-scale dialogue corpus, which is realized by means of intent understanding, retrieval and recall, and the generation method mainly uses resources on the Internet to train the neural network dialogue model. Due to the uneven quality of resources on the Internet, it is inevitable that the dialogue system will generate negative respo...
