Web Service Composition Discovery Based on Group Role Collaboration Service Aggregation
Towards two-objective constraint optimization problem for group performance and interaction cost,a service aggregation method based on Group Role Collaboration(GRC)is designed.Considering the collaboration performance and interaction cost among group members,an interaction cost calculation method is proposed.To resolve the problem of group role assignment,especially the"role"profile,group collaborative based semantic information is introduced to enrich the semantic description of services.A hierarchical clustering algorithm combining structure and semantic information is used to search for service candidate roles.It could improve the quality of service aggregation and resolve the dual objective constraint optimization between group performance and interaction cost.Experiments show that this method has obvious optimization effect on service aggregation in terms of satisfying service behavior compatibility and functional reliability.
