... parsing, syntax-based machine translation, morphological analysis, grammar induction, and finite-state operations. It is well known that various parsing algorithms for CFG and other formalisms can be ... efficient, portable, C++ classes that can be easily invoked from a larger application. By default, these classes run a generalization of agenda- based parsing, prioritizing the partial pa...

... non-transliterations by N. 3.2 Implementation Details We use the Forward-Backward algorithm to estimate the counts of multigrams. The algorithm has a for- ward variable α and a backward variable ... system learns this as a non-transliteration but it is wrongly annotated as a transliteration in the gold standard. Arabic nouns have an article “al” attached to them which is translated...

Marcu and Wong (2002) proposed a phrase-based alignment model which suffered from a massive parameter space and intr...

Each pair of anaphor and candi- date is represented as a PairInstance object, which is enriched with classification features by fea- ture extractors, and then handed over to a machine learning-based ... machine learning-based classifier that decides, given the fea- tures, whether anaphor and candidate are corefer- ent or not. Feature extractors are realized as sepa- rate...

The key additional feature we use, relative to (Ya- mada and Matsumoto, 2003), is that we include the previous predicted action as a feature. We also a...
