... approach for coreference resolution which uses the Bell tree to represent the search space and casts the coreference resolution problemas finding the best path from the root of the Bell tree to the leaf ... outcome, and there is no other way to form enti- ties. The Bell tree clearly represents the search space of the coreference resolution problem. The c...

... d controls the asymptotic growth of the number of unique words. In the last two pan- els, we show the proportion of words appearing only once among the unique words; this gives an indication ... machine translation. Most language models fall into the class of n-gram models, which approximate the distribution over sentences using the conditional distribution of each word given...

In the evaluation process, we considered only the true mentions of the ACE test dataset, and the event mentions of the test sets derived from a 5- fold cross validation scheme on the E CB ... these two corpora. Evaluation For a more realistic approach, we not only trained the models on the manually annotated event mentions (i.e., true mentions), but also on all...
