Abstract: Event reasoning requires support of commonsense event knowledge．We proposed a method of event know-ledge analysis in order to analysize preconditions and effects of events from multiple perspectives．In the process of ana-lysis we followed three phases:fundamental analysis,knowledge supplement,and knowledge optimization．We summarized four common sense knowledge dimensions to solve the problem of comprehensiveness and accuracy in analysis,which are physiological,psychological,social and physical．The method of role specification was proposed in the know-ledge supplement phase．Experiments show that this method is promising for acquiring comprehensive and accurate commonsense event knowledge.
