In the construction industry, there is a pressing need for computer systems that will facilitate
information exchange and knowledge sharing among all industry practitioners. The Social Semantic
Web Portal (SSWP) proposed in this paper will accomplish three tasks: (1) the streamlining of
information exchange about any individual project, (2) the encouragement of knowledge sharing in
general, and (3) the virtual grouping of people with similar interests to form communities of practice.
A domain ontology is developed in order to encapsulate knowledge about industrial actors and their
roles in relation to sibling ontologies that conceptualize construction products and processes. This
domain ontology is then tailored to be the cornerstone (the knowledge base) that will enable the
semantics of Web services. The concept of the Social Web is employed to validate knowledge items
and to connect users with similar interests. The information flow is realized through a
content-based publish/subscribe system. The SSWP will semantically connect a user with
knowledge items and socially link a user to his/her peers.
