The theory of Complexity Science and Hall for Workshop of Metasynthetic Engineering (HWME) is firstly summarized in this paper. The reason why HWME is a solution to complicated problems is discussed in succession. Based on C/S software structure, this paper proposes a software structure of meeting-discussion, in order to reduce the shortness of B/S software structure. From the viewpoint of software engineering, this paper describes the software structure, system description and running environment, human-machine interface, communication proxy, agent-oriented software design of HWME, thus reveals the software system of HWME. This paper proposes a novel approach for word clustering based on large tagged corpus. According to the need of decision-making support for a specific problem, this paper review several algorithms developed by previous works, after that, our algorithm is rendered. Firstly, we manually extract several words from a specified class, and then search the corpus for the modifiers of those words to construct modifier vector, for each of other words, count the frequency of its co-occurrence with each modifier in the modifier vector to construct its characteristic vector, finally, apply clustering algorithm to those characteristic vectors to get the result. Proved by experiment carried out on Decision-making Support for Macro Economics, this algorithm is effective for word clustering. This paper also proposes a surfing model, by utilizing the regularity of the user's previous visiting or rating, virtually extending the user's surfing length in the Web site, so more document has been rated or visited, and thus we can get a impact user-page matrix. We present experimental results that show how this approach performs better than the former.
