Abstract

We propose a new lexicalized grammar formalism called Lexicalized Tree Automata-based Grammar, which lexicalizes tree acceptors instead of trees themselves. We discuss the properties of the grammar and present a chart parsing algorithm. We have implemented a translation module for conversational texts using this formalism, and applied it to an experimental automatic interpretation system (speech translation system).
