The power of the Web is enhanced through the network effect
produced as resources link to each other with the value determined by
Metcalfe's law. In Web 2.0 applications, much of that effect is
delivered through social linkages realized via social networks online.
Unfortunately, the associated semantics for Web 2.0 applications,
delivered through tagging, is generally minimally hierarchical and
sparsely linked. The Semantic Web suffers from the opposite problem.
Semantic information, delivered through ontologies of varying amounts
of expressivity, is linked to other terms (within or between resources)
creating a link space in the semantic realm. However, the use of the
Semantic Web has yet to fully realize the social schemes that provide
the network of users. In this article, we discuss putting these together,
with linked semantics coupled to linked social networks, to deliver a
much greater effect.
The HCIL has a long, rich history of transforming the experience people have with new technologies. From understanding user needs, to developing and evaluating these technologies, the lab's faculty, staff, and students have been leading the way in HCI research and teaching.
