Incremental, Predictive Parsing with Psycholinguistically Motivated Tree-Adjoining Grammar [PDF]
Computational Linguistics, 2021 Psycholinguistic research shows that key properties of the human sentence processor are incrementality, connectedness (partial structures contain no unattached nodes), and prediction (upcoming syntactic structure is anticipated).

Multiple Adjunction in Feature-Based Tree-Adjoining Grammar [PDF]
Computational Linguistics, 2021 In parsing with Tree Adjoining Grammar (TAG), independent derivations have been shown by Schabes and Shieber (1994) to be essential for correctly supporting syntactic analysis, semantic interpretation, and statistical language modeling. However, the parsing algorithm they propose is not directly applicable to Feature-Based TAGs (FB-TAG).

Coordination in Tree Adjoining Grammars: Formalization and Implementation [PDF]
Proceedings of the 16th conference on Computational linguistics -, 1996 In this paper we show that an account for coordination can be constructed using the derivation structures in a lexicalized Tree Adjoining Grammar (LTAG). We present a notion of derivation in LTAGs that preserves the notion of fixed constituency in the LTAG lexicon while providing the flexibility needed for coordination phenomena.

Complexity, Parsing, and Factorization of Tree-Local Multi-Component Tree-Adjoining Grammar [PDF]
Computational Linguistics, 2021 Tree-Local Multi-Component Tree-Adjoining Grammar (TL-MCTAG) is an appealing formalism for natural language representation because it arguably allows the encapsulation of the appropriate domain of locality within its elementary structures.

Capturing CFLs with Tree Adjoining Grammars [PDF]
Proceedings of the 32nd annual meeting on Association for Computational Linguistics -, 1994 We define a decidable class of TAGs that is strongly equivalent to CFGs and is cubic-time parsable. This class serves to lexicalize CFGs in the same manner as the LCFGs of Schabes and Waters but with considerably less restriction on the form of the grammars.

Anchoring a Lexicalized Tree-Adjoining Grammar for Discourse [PDF]
, 1998 We here explore a ``fully'' lexicalized Tree-Adjoining Grammar for discourse that takes the basic elements of a (monologic) discourse to be not simply clauses, but larger structures that are anchored on variously realized discourse cues. This link with intra-sentential grammar suggests an account for different patterns of discourse cues, while the ...

Philosophies, 2021 Contemporary generative grammar assumes that syntactic structure is best described in terms of sets, and that locality conditions, as well as cross-linguistic variation, is determined at the level of designated functional heads.

Stochastic lexicalized tree-adjoining grammars [PDF]
Proceedings of the 14th conference on Computational linguistics -, 1992 The notion of stochastic lexicalized tree-adjoining grammar (SLTAG) is formally defined. The parameters of a SLTAG correspond to the probability of combining two structures each one associated with a word. The characteristics of SLTAG are unique and novel since it is lexieally sensitive (as N-gram models or Hidden Markov Models) and yet hierarchical ...

Tools and resources for Tree Adjoining Grammars [PDF]
Proceedings of the ACL 2001 Workshop on Human Language Technology and Knowledge Management -, 2001 This paper presents a workbench for Tree Adjoining Grammars that we are currently developing. This workbench includes several tools and resources based on the markup language XML, used as a convenient language to format and exchange linguistic resources.

The relationship between Tree Adjoining Grammars and Head Grammars [PDF]
Proceedings of the 24th annual meeting on Association for Computational Linguistics -, 1986 We examine the relationship between the two grammatical formalisms: Tree Adjoining Grammars and Head Grammars. We briefly investigate the weak equivalence of the two formalisms. We then turn to a discussion comparing the linguistic expressiveness of the two formalisms.
