Research on extraction of emergency event information based on rules matching

To provide high quality retrieval service of emergency event,result types of Chinese news event and the algorithm of inclusion relationship detection among the different result types are proposed. A method of extracting information of the emergency event is put forward. Firstly,the system will use the predefined rules to match every sentence of input files and normalizes the result information. Then,it will deal with the inclusion relationship of the result nodes and merge the result nodes. Finally,the structured output result is generated. The experiments show that methodologist and strategies are feasible.
