The specification discloses a question answer matching method, system and computer storage medium. The method comprises: transforming the user query and one of one or more suggested answers corresponding to the user query by using a pre-trained word vector to obtain vector representations of the user query and the one of one or more suggested answers corresponding to the user query; performing a convolutional operation on the vector representations of the user query and the one of one or more suggested answers, respectively, to extract features; and mapping convolution results of the vector representations of the user query and the vector expression of the one of one or more suggested answers into a sample annotating space, to obtain a matching result of the user query.
