Goals and Scope

Across three decades of study, the Tree Adjoining Grammar (TAG) formalism has provided interdisciplinary researchers in the cognitive science of language with an accessible, unifying framework within which they can share cutting-edge results on the mathematical and algorithmic properties of formal grammar, the grammatical description of natural language, and the mechanisms of human language use. The TAG+7 workshop aims once again to bring together the full range of researchers interested in the TAG formalism, in order to continue the kinds of productive interaction that have been the hallmark of TAG research. We anticipate holding sessions devoted to syntactic and semantic theory; mathematical properties; computational and algorithmic studies of parsing, interpretation and generation; psycholinguistic modeling; and applications to natural language processing.

A particular goal of the TAG+ workshop series (and the reason for the + in the workshop's name) is to explore relationships between TAG and other approaches to linguistic description. TAG connects with other syntactic formalisms (for example, with minimalist syntax, categorial grammar, dependency grammars, HPSG and LFG) through general properties such as lexicalization of syntactic structure, a simple notion of local grammatical dependency, or mildly context senstive generative capacity. Researchers have used these connections to enrich linguistic analyses in the TAG framework while clarifying the mathematical, computational or psychological implications of other linguistic frameworks. The increasing role of semantics in TAG research brings the challenge of extending this inventory of syntactic principles with a corresponding vocabulary to support formal, computational, descriptive and psycholinguistic investigations in semantics. We welcome submissions exploring these and other connections, and have planned a program of invited presentations, by Barbara H. Partee, F. J. (Jeff) Pelletier and Giorgio Satta, to further the interchange.


We invite submissions on all aspects of TAG and related systems. 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 type of submission, abstracts may not exceed two pages in length (not including data, figures and references). All abstracts must be submitted electronically to the following address:


(The period for submissions is now closed.)

Please use 'Abstract' as the Subject header and include the following information, which should constitute the body of the message:

  1. Name(s) of author(s)
  2. Affiliation(s)
  3. E-mail address(es)
  4. Postal address(es)
  5. Title of presentation
  6. Preference for talk or poster.
The anonymous abstract may then be included either in the body of the message in ASCII format, or else as a PDF attachment.


Proceedings including full 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.
