Abstract

The invention provides a method and equipment for training data of a natural language question-answering system, a computer readable storage medium and the natural language question-answering system.The method comprises the following steps: receiving original training data, wherein the original training data comprises at least one question in a question-answer pair form and a plurality of corresponding answers; determining data quality of the plurality of answers; based on the data quality, marking the plurality of answers as a first type of instances or a second type of instances; selectinga first type of instances and a second type of instances from the plurality of answers for combination to obtain a plurality of instance combinations; sorting the plurality of instance combinations, wherein the sorted instance combinations respectively correspond to training data of each time of training of the natural language question-answering system in a time sequence, the proportion of the first class of instances in the ranked plurality of instance combinations monotonically increases and the proportion of the second class of instances in the ranked plurality of instance combinations monotonically decreases.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, and more specifically, the present invention relates to a method and device for providing training data for a natural language question answering system, a computer-readable storage medium, and a natural language question answering system.
