Temporal relation theory is used to extract the occurrence time of the emergencies from web news. The Chinese temporal relation is firstly brought in. Then expressive features are summarized up from the composition, location and commonly used words of temporal information. The overlapping method of extracting occurrence time in web news is proposed and implemented by a system. The experiments based on the system prove that the method is satisfactory in precision and the occurrence time extraction is a very meaningful job.
