... standard available. Luckily, the Bayesian approach allows us to automatically select values for the hyperparameters by treating them as addi- tional variables in the model. We augment the model with ... average number of tags per token being 2.3. We varied the values of the hyperparameters α and β and evaluated overall tagging accuracy. For com- parison with our Bayesian...
