... relative frequency estimator corresponds to maximum likelihood (Chi and Geman 1998), and which we shall refer to as "ML-PCFG". To this end, we used a random 90%/10% division of WSJ40 into a training ... extends DOP1 to unsupervised parsing (Bod 2006). Its key idea is to assign all unlabeled binary trees to a set of sentences and to next use (in principle) all subtrees...

The representation of a canonical form for an identified PV is necessary to allow for individual rules to be associated with identified PVs in further processing and to facilitate ... as HPSG to integrate identification in deep parsing cannot be compared with the alternative finite state approach [Breidt et al. 1994].

For example, to determine how similar (the only sense of) “factory” is to the word “plant,” we compute the similarity of “factory” to the “in- dustrial plant” sense of “plant” and to the “living thing” ... vector θ. We wish to rank all possible words (i.e., the columns of M) so that the most promising word gets the highest score. A natural way to generate a score z j for column j...
