Research On The Technology Of Workflow Based Intelligent Collaborative Enterprise Portal

Workflow is a key technology to implement enterprise business process management and operating automation. It can help enterprises to improve the information resources utilization, operating efficiency, flexibility and applicability. This thesis is a research on the technology of workflow based intelligent collaborative enterprise portal, and the main achievements are as follows:On one hand, as the advantages of the B/S structure and the uniform entrance for accessing information resources in portal, workflow and portal technology are integrated to implement a workflow portal which can used to serve as the client of the workflow management system. The core functions of the process initialization, executing and control are also implemented. And the problem of workflow application data circulation is solved on the base of XSLT/XML technology.On another hand, in order to satisfy the personalization and intelligent support requirements for portal development, semantic web based context-aware computing and portal technologies are combined together into an intelligent portal structure. As the core of this structure, the framework of CA-MVC, which is based on context-aware computing and model-view-control pattern, is introduced in detail. The temporal context ontology is also given and main functions of context acquisition, context inference and context service modules are explained. Finally, a case study is presented.
