Abstract

The invention discloses a question matching method in an electric power intelligent question-answering system. The method comprises the following steps: firstly, carrying out zero filling or truncation operation on a query question P input by a user and a question Q in a system knowledge base to enable a sentence sequence to be changed into a fixed length; generating a corresponding word vector inthe sentence sequence through a GloVe model; inputting the word vector into a BILSTM model to obtain a word vector with context meaning; on the basis, extracting word vector features by using a convolutional neural network to obtain feature vectors of sentences, and further extracting common features from the feature vectors; and finally, splicing the feature vectors of the question P and the question Q and the common feature vector, and inputting the spliced feature vectors into a full connection layer to obtain a similarity prediction result. According to the method, deep learning is applied to the field of electric power intelligent questions and answers, the context of sentence words can be effectively fused, user questions are accurately matched, and the accuracy of electric power intelligent questions and answers is improved.
