"Regularity and Irregularity in Grammar and Language"


July 25

The workshops associated with HPSG conferences typically address topics that are relevant to any grammatical framework. Contributions to the workshop from other frameworks are as welcome as abstract submissions from the HPSG community!

The relationship between regularity and irregularity in language has always been a central research theme in linguistic theorizing. Contemporary grammatical frameworks in the generative tradition are no exception in this regard, with research dating back at least as far as George Lakoff's 1967 dissertation.

Head-Driven Phrase Structure Grammar is particularly well-suited to address such issues, due to its lexicalist orientation and to its extensive use of types and inheritance hierarchies. Consequently, HPSG researchers have made significant contributions to the study of regularity and irregularity in the areas of morphology, syntax and semantics. To name only a few examples:

Morphology and morphology-syntax interface: Flickinger's dissertation on lexical rules and the structure of the lexicon (Flickinger 1987); Nerbonne and Krieger's work on the organization of the lexicon and on inflectional morphology (Nerbonne and Krieger 1993); Riehemann's corpus-based study of derivational morphology (Riehemann 1998); Malouf's constructional approach to English gerunds.

Syntax and syntax-semantics interface: Przepiorkowski's account of case assigmnment in Polish (Przepiorkowski 1999); Sag's papers on assignment rules and exceptions in the English auxiliary system (Sag 2001); Ginzburg and Sag's constructional approach to the syntax and semantics of questions (Ginzburg and Sag 2001).

Semantics: research on licensing of special elements, including idioms (Riehemann 2001, Soehn 2006), n-words and negative polarity items (Przepiorkowski and Kupsc 1999; Sailer/Richter 1999; De Swart and Sag 2002).

We invite contributions that address issues related to the above research topics, that discuss theoretical issues in the treatment of regularity and irregularity in language, or that present empirical studies that pose interesting challenges to existing accounts.

The format of submission and the deadlines for the workshop will be identical to that of the main conference.

Submission Details

For both the main conference and the workshop, we invite online submissions of abstracts for presentations which should consist of two parts:

 1. a separate information page in plain text format, containing
   - author name(s)
   - affiliation(s)
   - e-mail and postal address(es)
   - title of paper

 2. an extended abstract of not more than 5 (five) pages, including all figures and references. Abstracts should be in PDF format.

We use an online subscription system. All abstracts should be submitted via http://www.easychair.org/HPSG2006 (If you have any questions: jp.soehn@uni-tuebingen.de).

Abstracts for the main conference should mention 'HPSG-06' and abstracts for the workshop should mention 'Workshop-06' in the subject line. All abstracts will be reviewed anonymously by at least two reviewers. Authors are asked to avoid self-references in the abstracts.

Important Dates

Abstract submission deadline: March 15, 2006
Notification of acceptance: May 15, 2005
Tutorial, Workshop, and Conference: July 24 - 27, 2006


The proceedings of the conference will be published on-line by CSLI publications. A call for papers for contributions will be issued after the conference. On-line proceedings of previous conferences are available at http://csli-publications.stanford.edu/HPSG/
