The hall for workshop of metasynthetic engineering (HWME) combines the experience &intelligence of all the generalized experts and the high capability of computer in the global level . Thus it is a knowledge system to solve the complex problem by the collective wisdom emerging from the network of HWME resulted from the interac2 tions among and between the generalized experts. HWME based on internet includes the experts , computer , internet and intranet . Because there is open dynamic complex in the group of experts , a rule of melting learning organization and merit of seminar into effective interaction is needed in HWME. This paper applies the information technology and artificial intelligence to implement the rule. With the addition of social thought technology such as system think2 ing and dialogue in depth to the dialogue theory and model in AI , a new , operable , embedded in human2computer interface , effective and applicable dialogue model is established , and a roomfor effective interaction is chosen to be intranet . This provides an effective path for the application research of social thought
