An expert system approach to improving stability and reliability of web service

In recent years, Internet service has become an important issue that attracts the researchers from both computer science and communication fields. Although many systems were proposed to support network-based e-activities, e.g., e-learning and e-commerce, few of them took into consideration web server management issues that are critical to the stability and reliability for providing Internet service. To cope with these problems, this study proposes a novel approach to eliciting and integrating system management knowledge from experienced system managers. An expert system for monitoring web servers has been implemented based on the novel approach; moreover, an experiment on an educational system has shown the superiority of the expert system in predicting and handling possible malfunctions or anomalies of web service systems.
