Abstract

The invention discloses a knowledge base question answering device and a method for establishing the knowledge base question answering device. The device comprises an index module, which is used for offline establishing a knowledge base with sentence vector index according to semantic vectors; A receiving module, configured to receive a user question and answer request; And a question and answer retrieval module, configured to retrieve answers to the questions and answers on line according to the user question and answer request in the knowledge base. The present application solves the technical problem of low efficiency in indexing a question answering knowledge base. As that index of the question answer knowledge base is established by the semantic vector, the efficiency is improved andthe index establishment time is reduced. In addition, the knowledge base question answering device of the present application can be applied to a question answering system for answering user questions.

Description

Technical field [0001] This application relates to the field of natural language processing, and specifically to a knowledge base question answering device and a method for establishing it. Background technique [0002] Question answering system usually refers to a question expressed in natural language, a certain degree of semantic analysis of natural language query sentences, and then search for possible candidate answers in the knowledge base and find the best answer through a sorting mechanism. [0003] The inventor found that when building a question and answer knowledge base, if the question text is used to build the question and answer knowledge base index, it is inefficient and requires a lot of labeling time. [0004] Aiming at the problem of low efficiency in establishing Q&A knowledge base indexes in related technologies, no effective solutions have been proposed yet. Summary of the invention [0005] The main purpose of this application is to provide a question and answer...
