TAG+9 2008


The Ninth International Workshop on Tree Adjoining Grammar and Related Formalisms (TAG+9)

7-8 June 2008
Tuebingen, Germany


Call For Papers (text version)

An important subfield of computational linguistics and natural language processing is research on the formal machinery for describing language. This covers a wide range of interdisciplinary work in the cognitive science of language, including the mathematical and algorithmic properties of this machinery, the grammatical description of natural language, and the mechanisms of parsing and human language use. This research is also applied to empirical areas leading to novel algorithms and models for machine learning.

Tree Adjoining Grammar (TAG) is a prominent formalism in the study of natural language because of its attractive formal properties and its extended domain of locality. TAG has been studied extensively in the last three decades with respect to mathematical properties and computational applications, as well as its role in constructing grammatical theories, new models of language processing and applications.

This workshop, the latest in a series that has been running successfully since 1990, aims at bringing together researchers interested in various aspects of the TAG formalism including relations to other grammar formalisms -- this is the reason for the "+" in the workshop's name. In the past, interaction between such formalisms has been productive, leading for example to the shared development of broad-coverage grammars, transfer of parsing and machine learning algorithms from one formalism to another and to new insights into properties of different formalisms. Such related formalisms would include minimalist syntax, categorial grammar, dependency grammars, HPSG, LFG, and others which share with TAG general properties such as lexicalization of syntactic structure, a simple notion of local grammatical dependency, and a formal system strictly more powerful than context-free but not fully context-sensitive.

Invited speakers:

  • Uwe Moennich, University of Tuebingen
  • Stuart Shieber, Harvard University


We invite submissions on all aspects of TAG and related systems including the following topics:

  • syntactic and semantic theory;
  • mathematical properties;
  • computational and algorithmic studies of parsing, interpretation and generation;
  • machine learning models for TAG;
  • corpus-based research and grammar development using TAG;
  • psycholinguistic modeling; and
  • applications to natural language processing or biological sequence modeling.

Anonymous abstracts may be submitted for two sorts of presentations at the workshop: spoken presentations and poster presentations. Poster presentations are particularly appropriate for brief descriptions of specialized implementations, resources under development and work in progress. Regardless of the type of submission, abstracts may not exceed two pages in length (not including data, figures and references). Both one-column or two-column abstracts are permissible. However do not use a font that is smaller than 11pt. If you are using LaTeX for document preparation, then any recent ACL style file can be used. The final camera ready will be in two-column format conforming to the most recent ACL style file.

Important dates:

  • Deadline for submission of abstracts: March 6, 2008. (deadline extended)
  • Notification to authors of decision: April 10, 2008.
  • Deadline for camera-ready submission: April 28, 2008.
  • Workshop dates: June 7 to 8, 2008.

Proceedings including full eight-page papers for accepted abstracts (including both oral presentations and poster presentations) will be available on-line and at the workshop. In addition, we will explore possibilities for subsequent publication of workshop articles, for example through a special issue of a journal.
