Obtaining Chinese entity relation pattern automatically is very important for entire information extraction system.Based on method of bootstrap and features that Chinese can express sanle meaning by many forms,using technology of statistical learning to obtain new pattern automatically.Experiment shows the method can find new pattern rapidly and need very small manual work,the process can't he limited by extract region.So the method is effective for promoting the function of information extraction system.
