METHOD AND DEVICE FOR PROCESSING QUESTION CLUSTERING IN AUTOMATIC QUESTION AND ANSWERING SYSTEM

摘要

The present invention provides a method and a device for processing question clustering in an automatic question and answering system. The method comprises: receiving a clustering request input by a writer; acquiring a question set to be clustered from a database of unanswered questions based on the clustering request; performing feature extraction on the question set to be clustered with a text feature extraction algorithm to output a question feature set; determining whether the question feature set meets a preset splitting condition; performing segmenting clustering on the question feature set with a segmenting clustering algorithm if the preset splitting condition is met to output at least two question feature subsets; updating the question feature subsets to a question feature set, determining whether the question feature set meets the preset splitting condition; and outputting the question feature set as a clustering class cluster if the preset splitting condition is not met.
