Abstract: Aiming at the goal and tenet of filtrating bad information, a real time monitoring prototype system for bad information based on the artificial neural networks is brought forward and is implemented by soft. Owing to the application of a new algorithm of artificial neural network in the decision-making module, the veracity of decision-making in the system is greatly improved. At the same time, some correlative problems, such as the speed of capture, transaction of the packages and the feasibility in economy, are dealt with in the system.
