f n c and assuming that each f i c is conditionally independent given l, we can approximate Expression (7) as: Furthermore, we assume that given context k, each candidate antecedent of z is generated with equal probability.
given Equations (4), (5), (8) and (9), we can rewrite P (l=1|z, k, c) as: As we can see from Equation 10, our model has one group of parameters, namely P (f i c |l=1).
