Argument linking in LTAG: A constraint-based implementation with XMG

摘要

This paper develops a first systematic approach to argument linking in LTAG, building on typologically oriented work in Van Valin (2005). While Van Valin's argument linking mechanism is procedurally defined, we propose a constraint-based implementation. The advantage is that we can separate between the linguistic generalizations to be captured and algorithmic considerations. The implementation is couched into the metagrammar framework eXtensible MetaGrammar (XMG).
