Abstract: An information monitoring method is provided which may track and monitor specific events of changing input data, such as stock market information, and notify venture capitalists or investors in real time of the occurrence of identified events of interest. According to the method to train or learn the quantitative patterns inherent in data sets, such as correlation between MAP and MAV, the relationship based on rules is built. A gray coefficient, trained by neural network under the specific events occurred in the historical data, is obtained for tracking and monitoring the present input data in real time. Artificial intelligence is therefore provided permitting adaptive monitoring of the input data in present invention.
