The current log data quality standards are developed based on artificial checking.It contains many qualitative standards.How to check log data under the qualitative standards is a difficult problem currently.The SVM method is used in abnormal amplitude checking of log data,suspicious samples are selected from log data, prediction model was established on the basis of log data and its checking result was given by experts.It can predict abnormal amplitude checking result,which avoids the problem that qualitative standards must be inverted into quantitative standards.It has shown good effects in practical application,so it is worth generalizing.
