[Purpose/significance] Historical Records is the first biographical history book in China, which contains almost all the significant historical events during more than 3000 years between the Yellow Emperor and the Emperor Wu of Han. How to efficiently extract these historical events and their relationships is quite important to penetrate the historical appearances, reveal the historical essences and discover the historical laws. [Method/process] The BERT model and LSTM-CRF model were introduced in this paper, and historical events extraction method based on Historical Records was proposed and the historical event graph was constructed. [Result/conclusion] The experiment results show that the F1 values of historical event and its components extraction are respectively 0.823 and 0.760. The rare known knowledge is invented by the event graph, which providing essential literature foundation for many researchers, such as philology, history and sociology, to conduct their researches.
