Converting an HPSG-based Treebank into its Parallel Dependency-based Treebank
Masood Ghayoomi, Jonas Kuhn · 2014
A treebank is an important language resource for supervised statistical parsers.The parser induces the grammatical properties of a language from this language resource and uses the model to parse unseen data automatically.Since developing such a resource is very time-consuming and tedious, one can take advantage of already extant resources by adapting them to a particular application.This reduces the amount of human effort required to develop a new language resource.In this paper, we introduce an algorithm to convert an HPSG-based treebank into its parallel dependency-based treebank.With this converter, we can automatically create a new language resource from an existing treebank developed based on a grammar formalism.Our proposed algorithm is able to create both projective and non-projective dependency trees.
