The Workshop on Tree-Adjoining Grammars
and related formalisms (TAG+) is a
biennial workshop series that fosters
exchange of ideas among linguists,
psycholinguists and computer scientists
interested in modeling natural language
using formal grammars. The workshop
series, since 1990, has demonstrated
productive interactions among
researchers and practitioners interested
in various aspects of the Tree-Adjoining
Grammar formalism and its relationship
to other grammar formalisms, such as
combinatory categorial grammar,
dependency grammars, Minimalist
grammars, HPSG, and LFG; hence the "+"
in the name of the workshop.
Tree-Adjoining Grammars (TAG) and
related lexicalized grammar formalisms
provide mathematical tools to model
natural language and the scaffolding to
encode linguistic generalizations in a
principled manner. In the past, this
workshop has helped identify
similarities and differences between the
above formalisms, leading 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 the properties
of different formalisms and their
capacity for linguistic explanation. It
is our expectation that this edition of
the workshop will continue enabling
cross-fertilization of ideas that
combine the representational flexibility
of TAG-like grammar formalisms with the
robustness afforded by machine learning
techniques to produce a deeper insight
into modeling of natural language.
