The closest experiment to ours is the one by Gao & Johnson (2008) who run their Bayesian HMM over the whole WSJ and evaluated against the full gold standard, the only difference being is that we exclude the CoNLL shared task sec-    Table 2: Performance of the output of the three iHMM runs when used in shallow parsing against number of iteretions (in thousands).
since the sum of the entries must sum to one, the rows of the transition matrix will be zero everywhere and all its mass in a random location.
