In this paper, an intelligent post-editor is proposed.In the editor,feedback messages suitable to backward inference can be formed to the knowledge acquisition mechanism to improve the knowledge of MT system.In addition,the number of delete and insert operations can be greatly reduced by using the multiple solution ability of the system's translation mechanism,making the users select correct result from several candidate strings rather manually deleting error string and insert correct string. Furthermore,the efficiency of post-editing can be enhanced by providing automatic adjusting the order of parts in output and the synchronous display of source text and target text.
