NAACL-HLT 2012 Workshop on Inducing Linguistic Structure
Welcome to the homepage of the NAACL-HLT 2012 Workshop on Inducing Linguistic Structure. This workshop addresses the challenges of learning in an unsupervised or minimally supervised context with questions of linguistic structure. It encompasses many popular themes in computational linguistics and machine learning, including grammar induction, shallow syntax induction (e.g., parts of speech), learning semantics, learning the structure of documents and discourses, and learning relations within multilingual text collections. Unlike supervised settings, where annotated training data is available, unsupervised induction is considerably more difficult, both in terms of modelling and evaluation.

- Christos Christodoulopoulos
- David Marecek
- Grzegorz Chrupla
- Anders Soergard

Paper submissions
We solicit papers from many subfields of computational linguistics and language processing. Topics include, but are not limited to - grammar learning - part-of-speech and shallow syntax - learning semantic representations - inducing document and discourse structure - learning/projecting structures across multilingual corpora - relation induction across document collections - evaluation of induced representations Our aim is to bring together work on fully unsupervised methods along with minimally supervised approaches (e.g., domain adaptation and multilingual projection).
The workshop will solicit short papers (6 pages of text, up to 2 pages of references) for either oral or poster presentation. We will consider allowing additional pages for accepted papers to give space to address the reviewer comments. Please follow the standard NAACL guidelines for paper formatting (details here). You can submit your papers using the following link
