Abstract: On the purpose of carrying out dynamic task assignments and dynamic resource pushing in multi-person collaborative work, a Personalized Service model Based on Task of Role（PSBTR） is proposed for web-based large-scale application. The meta-model of role, task, resource, etc that involved in workflow are described formally so as to construct a united base for applications. Then match algorithms of task and resource base on their role characteristics and task lord are built. According to the task states in the collaborative environment, related tasks and resource are pushed to user. A case study is given to verify the feasibility and effectiveness of the model. The result shows that the model also provides a reference approach for the resource push mechanism in large-scale service application.
