The Study of Backup Mechanism for Web Services Based on MAS and Topic Maps

This study proceeds with its development on the JADE platform, follows PASSI methodology in MAS analysis and design, and utilizes topic maps for e-learning (TM4L) to construct topic maps. During the service execution period, should a provided service failure occurs, the agent will automatically select a service with the higher evaluation value from the candidate service list to proceed with the service backup mechanism through parameter conversions. If the substitute service contains a semantic discrepancy, a light-weighted ontology will be used, which means a topic map conversion will take place. Finally, this study will design an experiment to verify the viability of the backup mechanism, and conduct the evaluation and discussion on the system´s efficiency.
