GEMS -- GEometrical Models of natural language Semantics
Workshop at EMNLP, July 31st 2011, Edinburgh, Scotland

In accordance with the general EMNLP schedule, we have decided to extend
the deadline for the GEMS Workshop. The schedule now looks as follows: 

May 19, 2011: Papers due
June 19, 2011: Notification of acceptance
July 1, 2011: Camera-ready deadline
July 31, 2011: Workshop

GEMS 2011 is the third event in a series of workshops on distributional
models, also known as semantic spaces. These models have become
omnipresent in computational linguistics and neighboring fields.
In this second call for papers, we draw attention to the shared 
evaluation, the data for which are now available through the website.

GEMS 2011 invites original contributions to problems in meaning
representation, acquisition and use, based on distributional and
vector space models. We are interested in methodological innovations
as well as tasks ranging from the induction of linguistic and world
knowledge to practical and industrial NLP applications.

GEMS 2011 will also address one particular challenge of geometrical
models as a scientific field, namely fragmentation -- with respect
to data sets, methods and evaluation metrics. To facilitate the
comparison of studies and achieve scientific progress, GEMS will
introduce a shared evaluation:

- We provide two datasets suitable for the evaluation of distributional 
models through our website, together with the corpora that can be used
for their modeling. 
- These datasets cover two major tasks: differentiating between semantic 
relations and addressing compositionality.
- Papers submitted to GEMS are strongly encouraged to evaluate their 
models on one of the datasets, or, if this is not possible, to discuss why 
their models are not applicable.


Topics of interest include, but are not limited to

- Document-based, collocational and syntax-based spaces
- Eigenvector methods and geometrical embeddings
- Higher order tensors
- Computational complexity and evaluation issues
- Graph-based models over semantic spaces
- Logic and inference in semantic spaces
- Large-scale implementations of distributional models (Map-Reduce, Hadoop)
- Kernels methods for NLP
- Word sense discrimination and discrimination; lexical substitution
- Induction of selectional preferences
- Compositionality in geometrical models: phrase representation; concept combination
- Lexicon acquisition
- Conceptual clustering
- Modeling of linguistic theories and ontological knowledge
- Cognitive theories of semantic space models
- Applications in the humanities and social sciences
- Applications and impact on Web search, Web mining, Query log mining, 
Query Intent Modeling, and other industrial activities


Authors are invited to submit papers on original, unpublished work on
the topics of this workshop. There are three paper categories: long papers, 
short papers and demos.

- Long papers should present completed work. They can have
up to 9 pages of content, plus references.
- Short papers/demos can present work in progress or the description 
of a system. They must not exceed 4 pages plus one page of references.

Submissions should follow the two-column format of the ACL 2011
proceedings (see the official style files at
http://www.acl2011.org/call.shtml). As reviewing will be blind, please
ensure that papers are anonymous. The papers should not include the
authors' names and affiliations or any references to web sites,
project names, etc. revealing the authors' identity. 

Each submission will be reviewed by at least two members of the
program committee. Accepted papers will be published in the workshop
