Abstract

The invention discloses an intelligent question-answering method and device, and relates to the technical field of computers. A specific embodiment of the intelligent question-answering method comprises the steps of generating a semantic feature vector set according to a dialogue record in a current dialogue process of a first user and a customer service, the semantic feature vector set comprisinga semantic feature vector of the dialogue record in the current dialogue process; performing semantic aggregation on the semantic feature vector set to obtain a first aggregated semantic vector representing the real intention and semantics of the current question of the first user; and searching a semantic vector matched with the first aggregated semantic vector from a knowledge base storing question and answer information, and outputting an answer to the current question according to the searched semantic vector. According to the embodiment, the context information can be effectively utilized for retrieval, and the accuracy of information retrieval in a multi-round dialogue scene is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an intelligent question answering method and device. Background technique [0002] In recent years, intelligent question answering technology has developed rapidly, mainly due to the rapid development of deep learning technology and its deep integration with natural language processing technology. Existing intelligent question answering systems are usually based on information retrieval or sequence generation. In commercial applications, due to the uncontrollability of sequence generation, more information retrieval models are used. In addition, in order to achieve specific business goals, a rule-based approach is usually adopted in dialogue state control, sacrificing the openness of the dialogue system in exchange for dominance of the dialogue process (state). In addition to deep learning, intelligent dialogue systems also widely use knowledge graph technology to deal with fa...
