生物医学事件触发词识别研究
Research on identification of biomedical event trigger
摘要
Abstract
The trigger identification is a key step in the biomedical event extraction.The traditional method based on dictionary or rules are too dependent on the establishment of a dictionary or rules,while general machine learning methods need to design complex features,even most systems that adopt the serial method lead to the error propagation.From two dimensions of algorithm and the whole process to optimize,the system used a joint structure prediction model of event trigger identification and event type determination based on neural network.It simplified the manual intervention,and reduced error propagation.The evaluation shows that this proposed approach achieves good performance,which lays the reliable foundation of the biomedical event extraction.关键词
