DGfS Workshop 'Learning Meets Acquisition'
  ==========================================


   EXTENDED call Deadline: 31-Aug-2008
   Call for papers for the DGfS 2009 in Osnabrück, Germany (last call):


     AG Learning meets Acquisition:
   The learnability of linguistic frameworks
   from formal and cognitive perspectives

The workshop brings together researchers working on the learnability of 
linguistic models from a formal point of view, with those working on the 
models' cognitive adequacy.

In general, studies on the learnability of language account for how grammar and 
lexicon of a language can be learnt, and by what means. To give an example, 
considerate progress has been made recently in connectionist-based frameworks 
such as Optimality Theory (Prince & Smolensky 1993) and Harmonic Grammar 
(Legendre et al. 1990). Most learnability models within OT deal with the 
learning of the grammar: learning of constraint hierarchies, and learning of 
constraints themselves. In most of these approaches, lexical information is 
already given. Other OT approaches tackle the learning of parts of the lexicon. 
Differences between approaches include whether lexicon and grammar are learnt 
in turns (offline) or in parallel (online), or whether the OT grammar to be 
learnt is traditional or stochastic. Current approaches to learnability within 
HG include learning constraint weights, by using learning algorithms such as 
the perceptron algorithm. Yet, formal results have been only seldom tested 
against empirical data from language acquisition research.

The workshop will not only capture the State-of-the-Art in current approaches 
to learnability, but also point out future developments in this field, 
especially those pertaining to cognitive adequacy. Questions to be addressed in 
the workshop include:

- What are appropriate computational models of the formalizations and why?
- What is the cognitive and psycholinguistic plausibility of these models?
- How does the research on formal models of learnability relate to 
(psycholinguistic) research on language acquisition? Is there a ''missing 
link''?
- How can the learnability of interfaces (e.g., syntax-phonology, 
semantics-phonology) be formalized?
- How can learnability account for diachronic aspects of language?

We invite anybody working within any well-established contemporary linguistic 
framework (including phonology, syntax or semantics, let it be GB, the 
Minimalist Program, OT, LFG or HPSG among many others), and who tackles its 
learnability from a theoretical, formal or cognitive perspective. Especially 
invited are contributions that contrast the learnability of a framework with 
empirical data (from language acquisition, language change or psycholinguistic 
experiments).

Abstract submission guidelines:
- Abstracts should be submitted for 30-minute slots (including discussion).
- 1 page (TimesNewRoman, 12pt, single-spaced, A4 margins), including references 
and figures etc.

- Abstracts should be submitted via e-mail as attachment. The names and 
affiliations of the authors along with the title of the abstract should be 
included in the body of the e-mail.
