Abstract

The invention discloses a method and device for generating data in a database. The method comprises the steps that a first answer is determined according to existing knowledge; the first answer is provided to an annotator, and the annotator is required to return a first question adapted to the first answer; and the first question returned by the annotator is matched with the first answer and then stored in the database. By the adoption of the method and device, on the premise that the answer quality is guaranteed, the public serving as annotators can participate in, the workload and cost are reduced, and the method and device are also suitable for databases with professional requirements; that is, compared with a common annotator, the answer is more reliable; and compared with only specialists for labeling, the workload of the specialists is reduced, and more training data can be collected.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and device for generating data in a database. Background technique [0002] In daily life, more and more people have the opportunity to enjoy the convenience brought by intelligent customer service and intelligent interactive question and answer system. For example, intelligent customer service robots can partially replace human customer service to answer common questions, greatly reducing the workload of human customer service. [0003] Among them, the data establishment of the question-answering knowledge database is a very important part of this type of intelligent question-answering system. [0004] The existing schemes are: [0005] Experts write preset QA pairs (question-answer pairs) according to the template, or the public provides questions and answers. [0006] The disadvantage of the prior art is that the workload and cost of QA pairs written solely by ex...
