UDLex: Towards Cross-language Subcategorization Lexicons

This paper introduces UDLex, a computational framework for the automatic extraction of argument structures for several languages. By exploiting the versatility of the Universal Dependency annotation scheme, our system acquires subcategorization frames directly from a dependency parsed corpus, regardless of the input language. It thus uses a universal set of language-independent rules to detect verb dependencies in a sentence. In this paper we describe how the system has been developed by adapting the LexIt Lenci et al., 2012) framework, originally designed to describe argument structures of Italian predicates. Practical issues that arose when building argument structure repre- sentations for typologically different languages will also be discussed.
