Feature Selection for a Rich HPSG Grammar Using Decision Trees
Feature Selection Rich HPSG Grammar Decision Trees
2015/6/12
This paper examines feature selection for log linear models over rich constraint-based grammar (HPSG) representations by building decision trees over features in corresponding probabilistic context fr...
In this paper, we describe experiments on HPSG parse disambiguation using the Redwoods HPSG treebank (Oepen et al. 2002a,b,c). HPSG is a constraint-based lexicalist (“unification”) grammar formalism.
