To realize the automatic and on-demand integration of web services, it is necessary to resolve such issues as the high-level task decomposing and the goal planning at the concept level. We propose a process ontology model by adopting an inheritance mechanism with overriding declaration and monotonic inheritance. The inherited relation among processes implies a layered structure of task decomposing. A framework of automatic composition of web services at knowledge level is proposed.
