Zusammenfassung:According to the event information extraction method and device, event information extraction is carried out through a pre-training model, the training cost can be effectively reduced, good portability is achieved, semantic continuity is guaranteed, and recognition errors are avoided. The method comprises the steps of dividing a target text into a plurality of sub-texts based on continuous semantic information, wherein the sub-texts are used for representing a text containing the continuous semantic information; executing the following process for each sub-text: inputting the sub-text into a trained pre-training model, and outputting entity information related to an event in the sub-text; and determining the event information extracted from the sub-text according to the entity meeting the length requirement in the entity information. 本发明公开了一种事件信息抽取的方法及设备,采用预训练模型进行事件信息抽取,能够有效降低训练成本,具有较好的移植性,还用于保证语义的连续性、避免识别错误。该方法包括:基于连续语义信息将目标文本划分成多个子文本,所述子文本用于表征包含连续语义信息的文本;针对每个子文本执行如下过程:将所述子文本输入到训练好的预训练模型,输出所述子文本中与事件相关的实体信息;根
