This paper presents socio-semantic web applications based on the Hypertopic knowledge representation model. The Hypertopic [4] model is used to collaboratively construct topic maps with multiple user points-of-view within related communities. Three model building methods are presented herein: centralized, conflict-based, and hybrid. These methods are expressed using the socio-technical ‘SeeMe’ notation and method [7,8]. This paper will also illustrate how various co-building approaches can be used to construct Hypertopic maps in real communities.
