Han Liang · Zhongwen xinxi xuebao · 2006
Information extraction technologies can provide high quality retrieval service.In this paper we present an information extraction model based on event frame,and build an unified calamity event frame.The extraction system can be easily implemented due to the inheritance and induction characters of the frame.We also use the frame to collect event information and then output the results in the order of time.A calamity event information extraction system is conducted using the methods.The experiment indicates the methods are feasible.
