We show using part- of- speech tagging that a fully Bayesian approach can greatly im- prove performance. Rather than estimating a single set of parameters, ... optimal set of parameter values, we seek to directly maximize the probability of the hidden variables given the ob- served data, integrating over all possible parame- ter values.
