Abstract: Text was expressed by the means of event,and event ontology was built by using event as the basic semantic unit.According to the relationship between events,we built event network direct diagram which can express more semantic information of the text and describe the importance of relationship between events.The importance degree of event of the event network corresponding to each node was calculated and ranked by using the PAGERANK algorithm.According to the time sequence of events,event corresponding primitives were exported as abstract.The experimental results show that automatic summary based on the event network method has better performance.

Key words: Text representation,Event ontology,Event-Network,PAGERANK
