... on the point estimation of words’ context profiles obtained from a limited amount of data. This paper proposes a Bayesian method for robust distributional word similarities. The method uses a ... calculation of distributional similarity. The method is straightforward: Instead of using the point estimation of v(w i ), we first estimate the distribution of the cont...
