Abstract: A method to study a seminar issue of human-computer combination by the idea of workflows integration is proposed. Making use of all resources and based on seminar workflows, the seminar of human-computer combination can make new information. Adaptors are adopted to implement the integration of a single seminar task workflow. The integration of multiple seminar task workflows is implemented by the architecture composed of seminar workflows, seminar subtasks, and seminar objects. Inter-operation among different workflows is implemented by extensible language for business communication（XLBC）.
