========================================================</div>
TextGraphs-6: Graph-based Methods for Natural Language Processing<br>
==============================
<div>==========================<div><br>Workshop at ACL-HLT 2011<br>Association for Computational Linguistics Conference<br>Portland, Oregon<br><br></div><div><a href="http://www.textgraphs.org/ws11/" target="_blank">http://www.textgraphs.org/ws11/</a><br>
<br></div><div>Deadline for paper submission: April 1st, 2011</div><div><br>*******************************************************************<br>TextGraphs
is at its SIXTH edition! This shows that two seemingly distinct
disciplines, graph theoretic models and computational linguistics, are
in fact intimately connected, with a large variety of Natural Language
Processing (NLP) applications adopting efficient and elegant solutions
from graph-theoretical framework.<br>
<br></div><div>The TextGraphs workshop series addresses a broad spectrum
of research areas and brings together specialists working on
graph-based models and algorithms for natural language processing
and computational linguistics, as well as on the theoretical foundations
of related graph-based methods. <br>
<br></div><div>This workshop series is aimed at fostering an exchange of
ideas by facilitating a discussion about both the techniques and the
theoretical justification of the empirical results among the NLP
community members. Spawning a deeper understanding of the basic
theoretical principles involved, such interaction is vital to the
further progress of graph-based NLP applications.<br>
<br></div><div>Special Theme: ''Graphs in Structured Input/Output Learning''<br>-------------------------------------------------<br><br></div><div>Recent work in machine learning has provided interesting approaches to globally represent and process structures, e.g.:<br>
- graphical models, which encode observations, labels and their dependencies as nodes and edges of graphs;<br>- kernel-based machines which can encode graphs with structural kernels in the learning algorithms; and<br>-
SVM-struct and other max margin methods and the structured perceptron
that allow for outputting entire structures like for example graphs.<br>
<br></div><div>To make such methods effective both from efficiency and
accuracy viewpoint, when using graphs as input and output, the typical
graph properties must be exploited at the best. Our aim is to bring
together researcher experts in graph theory and experts in
machine learning for structure predictions from structured input in
order to enable cross-fertilization of ideas. The proposed theme will
encourage publication of early results and initiate discussions of
issues in this area. We hope that this will help to shape future
directions for improving both efficiency and accuracy of algorithms
dealing with structured input/output, where graphs are seen as the main
tool to model natural language processing data.<br>
<br>Special Issue:<br>-------------------<br><br></div><div>High quality
papers of Textgraphs-6 that are related to the special theme will be
invited to submit to the JNLE special issue on ''Statistical Learning
of Natural Language Structured Input and Output'' </div>

- regular full papers of max. 8 pages (one additional page for the Reference section only is allowed, for a maximum of 9 pages)<br>- regular short papers of max. 4 pages<br>-
position papers of max. 4 pages (describing new scenarios for the use
of graphs for text processing, especially in the field of Graphs in
Structured Input/Output Learning).<br>
<br></div><div>All submissions must be electronic in PDF and must be formatted using the ACL-HLT 2011 Style Files (see <a href="http://www.acl2011.org/call.shtml#submission" target="_blank">http://www.acl2011.org/call.shtml#submission</a>).</div>
<div><br>* Multiple-submission policy<br>Papers that have been or will
be submitted to other meetings or publications must indicate this
at submission time. Authors submitting multiple papers to TextGraphs-6
may not submit papers that overlap significantly (50%) with each other
in content or results. Authors of papers accepted for presentation at
Textgraphs-6 must notify the organizers immediately as to whether the
paper will be presented. All accepted papers must be presented at the
conference in order to appear in the proceedings.</div>
<div><br>* Blind review policy<br>In order to facilitate blind
reviewing, the authors should omit their names and affiliations from
the paper. Furthermore, self-references that reveal the author's
identity, e.g., ''We previously showed (Smith, 1991) ...'' must be
avoided. Instead, use citations such as ''Smith previously showed
(Smith, 1991) ...'' Papers that do not conform to these requirements
will be rejected without review.<br>
<br></div><div>* Submission<br>Papers should be submitted to the START Conference Manager at <a href="https://www.softconf.com/acl2011/textgraphs/" target="_blank">https://www.softconf.com/acl2011/textgraphs/</a>.</div><div>
