Abstract:

This paper describes an implemented algorithm for syntactic realization of a target-language sentence from an interlingual representation called Lexical Conceptual Structure LCS. We provide a mapping between LCS thematic roles and Abstract Meaning Representation AMR relations these relations serve as input to an off-the-shelf generator Nitrogen. There are two contributions of this work 1 the development of a thematic hierarchy that provides ordering information for realization of arguments in their surface positions 2 the provision of a diagnostic tool for detecting inconsistencies in an existing online LCS-based lexicon that allows us to enhance principles for thematic-role assignment.
