Abstract

The invention provides a data error correction method and apparatus facing a question answering system. The method comprises: receiving information input by a user, and converting the information input by the user into standard text format information, wherein the information input by the user comprises voice information and / or text information; carrying out de-noising processing on the standard text format information, and acquiring first information; carrying out error distinguishing on the first information by utilizing an error word bank; when the first information comprises error contents, extracting the error contents in the first information; and replacing the error contents according to a preset processing algorithm, and acquiring and outputting second information. According to the data error correction method and apparatus facing the question answering system, which are provided by the invention, input errors of the user on the question answering system can be effectively reduced, so that a correction rate that the question answering system answers questions of the user is improved, and user experience of the question answering system is effectively promoted.

Description

technical field [0001] The invention relates to the field of information retrieval and query, in particular to a data error correction method and device for question answering systems. Background technique [0002] Question answering system is an advanced form of information retrieval system, which can answer questions raised by users in natural language with accurate and concise natural language. The main reason for the rise of its research is people's demand for fast and accurate access to information. The question answering system refers to the natural language understanding technology as the core, so that the machine can understand the user's speech content, and realize the effective communication between the human and the machine. It is an artificial intelligence system that automatically talks to the user through the natural language technology. At present, question answering systems are widely used, mainly in computer customer service systems, robots, children's toys...
