Tree-Adjoining Grammar: A Tree-Based Constructionist Grammar Framework for Natural Language Understanding.
AAAI Spring Symposia(2017)
摘要
In this paper, we propose to use Tree-Adjoining Grammar(TAG) as a means to formalize central tenets of ConstructionGrammar (CxG). We will show that TAG, beyond its lexicalized elementary trees, provides several levels of grammatical abstraction that correspond to constructions. In other words, within the specification of a TAG one can find specifications of non-lexicalized syntactic tree fragments with their attached meaning. This allows to capture many of the insights from CxG in an explicit way. Moreover, TAG is a well-established framework in mathematical and computational linguistics. These properties make TAG a highly relevant contender for hosting constructionist implementations of natural language understanding.
