<P>PROBLEM TO BE SOLVED: To provide a driving monitoring method improved in predicting a risk, state, and abnormality of vehicle driving. <P>SOLUTION: The driving monitoring method includes steps of: obtaining a training data stream of vehicle dynamic parameters and recording data showing crash instances; labeling the training data that overlap the data showing the crash instances in the training data stream as most risk; labeling the training data, which are furthest from the data that are labeled as most risk, as most safe; propagating information on the risk evaluation level of the labeled training data to unlabeled data; estimating parameters of a risk-level predicting function using the labeled and unlabeled training data; and applying the risk-level predicting function to an actual data stream. <P>COPYRIGHT: (C)2009,JPO&INPIT
