Embodiment Construction

[0033] As mentioned in the background technology, in the existing technology based on rules, template matching, and retrieval methods, templates, examples, or databases have limitations, and lack of effective language understanding, resulting in certain problems in the accuracy and flexibility of answers. Insufficient; based on the generative method, it is necessary to establish and train the model, the complexity of the model is high, and the stability of the answer acquisition process is low.

[0034] The technical solution of the present invention uses at least two methods to obtain multiple answers, and then selects the optimal answer output among multiple answers; because the methods of obtaining answers are different, the richness of answers can be improved from multiple angles, and a single method can be avoided If the answer cannot be obtained, it ensures the sustainability of the Q&A interaction with the user and improves the user experience. In addition, selecting th...

Abstract

The invention provides an intelligent question and answer system and an intelligent terminal. The intelligent question and answer system comprises a user question obtaining module used for obtaining user questions; an answer obtaining module which is used for obtaining a plurality of answers for the user questions in at least two modes, wherein the modes comprise a knowledge base, a knowledge graph and a learning model; an answer screening module which is used for screening the answers according to the source parameters and the prediction probabilities of the answers, wherein the source parameters and the prediction probabilities of the answers are determined according to the obtaining mode of the answers; and an answer output module which is used for outputting the screened optimal answer. According to the technical scheme, the response accuracy and continuity in the question and answer interaction process can be improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to an intelligent question answering system and an intelligent terminal. Background technique [0002] In the field of artificial intelligence technology applications, more and more intelligent question answering products have emerged. Generally speaking, the accuracy and speed of responses to user questions are important factors that affect the quality of intelligent question answering products. [0003] There are many question and answer processing methods in the prior art, and commonly used methods are rule-based, template-matching-based, retrieval-based, and generative-based. Among them, the retrieval-based approach is to generate answers by retrieving existing knowledge points in the knowledge base. The knowledge base usually includes multiple knowledge points, and each knowledge point includes standard questions and corresponding extended questions and ans...
