... accu- racy compares among the models. With HMM features, the M- estimator is about the same as the HMM and MEMM (better than PL and worse than the CRF). With extended features, the M- estimator lags ... experiment gives some insight into the relative importance of extended features versus es- timation methods. The M- estimated model is, like the maximum likelihood-estimated HMM, a gener- a...

... Rosetta gram- mar formalism, called M- grammars, was a computa- tional variant of Montague grammar. The formalism was introduced in Landsbergen(1981). Whereas rules in Montague grammar operate ... introduces some extensions of the formalism, which make it possible to assign more struc- ture to an M- grammar. The new formalism was called controlled M- grammars. In this new approach a...
