    We present an algorithmic framework for learning multiple related
    tasks.  Our framework exploits a form of prior knowledge that relates
    the output spaces of these tasks.  We present PAC learning results
    that analyze the conditions under which such learning is possible.
    We present results on learning a shallow parser and named-entity
    recognition system that exploits our framework, showing consistent
    improvements over baseline methods.
