This paper describes a general metarule treatment of English whconstructions (relative clauses, and questions ) in the context of a broad -coverage logic grammar that also includes an extensive metarule treatment of co-ordinate conjunction . ' Vh-constructions pose difficulties for parsing , due to their introduction of a dependency between the wh-word (e.g., which ) and a corresponding gap in ...

We describe the construction of a large lexicalized tree adjoining grammar for Italian, automatically extracted from an annotated corpus. We first introduce the TUT, a dependency style treebank for Italian, then we illustrate the algorithm that we have designed to extract the grammar, and finally we report two experiments about parsing complexity and coverage of the extracted grammar.

Grammatical Framework (GF) is a grammar formalism which supports interlinguabased translation, library-based grammar engineering, and compilation to speech recognition grammars. We show how these features can be used in the construction of portable high-precision domain-specific speech translators.

Syntactic parsing in NLP is the task of working out the grammatical structure of sentences. Some of the purely formal approaches to parsing such as phrase structure grammar, dependency grammar have been successfully employed for a variety of languages. While phrase structure based constituent analysis is possible for fixed order languages such as English, dependency analysis between the grammat...
