This paper examines a new technique based on tableau, that allows one to introduce composition of roles from the right hand side of complex role inclusion axioms (RIAs). Our motiva...
A sequence fn(q) is q-holonomic if it satisfies a nontrivial linear recurrence with coefficients polynomials in q and qn . Our main theorem states that q-holonomicity is preserve...
Though toolkits exist to create complex crowdsourced workflows, there is limited support for management of those workflows. Managing crowd workers and tasks requires significant i...
