  This paper proposes a novel framework for representing community know-how on
the Semantic Web. Procedural knowledge generated by web communities typically
takes the form of natural language instructions or videos and is largely
unstructured. The absence of semantic structure impedes the deployment of many
useful applications, in particular the ability to discover and integrate
know-how automatically. We discuss the characteristics of community know-how
and argue that existing knowledge representation frameworks fail to represent
it adequately. We present a novel framework for representing the semantic
structure of community know-how and demonstrate the feasibility of our approach
by providing a concrete implementation which includes a method for
automatically acquiring procedural knowledge for real-world tasks.
