Abstract | In natural language processing, intelligent question answering based on knowledge graph has received great attention. In the previous knowledge base question answering, the traditional word vector is difficult to express the text semantic information, and the cyclic neural network is easy to cause gradient disappearance and gradient explosion. At the same time, it is lack of comprehensive consideration of text context information. This paper proposes an intelligent Q & A method based on knowledge graph, which uses BiLSTM-CRF model to realize entity recognition. The intelligent Q & A model is constructed based on Seq2Seq, and the above methods are verified by taking the intelligent Q & A as an example, which effectively improves the accuracy of intelligent Q & A. |
