Problem extension method and device, electronic equipment and medium

Abstract

The invention relates to an artificial intelligence technology, and discloses a problem extension method, which comprises the steps of performing label text retrieval according to an original text setto obtain a label text set; carrying out extension problem prediction on the original text set by utilizing a problem extension model to obtain a prediction text set; calculating a first loss value between the original text set and the prediction text set and a second loss value between the prediction text set and the label text set to obtain a final loss value; adjusting internal parameters of the problem expansion model according to the final loss value until the final loss value is smaller than a preset threshold value, and obtaining a standard problem expansion model; and performing extension prediction on the to-be-extended text by utilizing the standard problem extension model to obtain an extended text set. The invention also relates to a blockchain technology, and the label text set and the like can be stored in a blockchain node. The invention further discloses a problem expansion device, electronic equipment and a storage medium. According to the invention, the problem thatthere is no extended question or there are few extended questions in newly added questions of the knowledge base can be solved.

Description

Technical field [0001] The present invention relates to the field of artificial intelligence, and in particular, a problem extension method, a device, an electronic device, and a computer readable storage medium. Background technique [0002] The problem of answering users with intelligent customer service has been widely used in all walks of life. When answering the user's question, the smart customer service needs to rely on the knowledge base, so the quality of the knowledge base directly determines the quality of service of the smart customer service. The knowledge base is generally composed of standard questions, extensions, and answers. When the user puts forward a problem, the intelligent customer service will match the extension question one by one, and revealed the standard asking for the answer and feedback to the user, but the same intention The user's question method is more flexible, it is easy to hit the extension, especially the problem of new knowledge bases, such...
