(1) Workshop Description
==================================================

Recent years have shown an increased interest in integrating various
aspects of the field of Graph Theory (GT) into Natural Language
Processing (NLP). Many language phenomena can be naturally put into
graph-based representations and in the last 5 years a significant
number of NLP applications adopted efficient and elegant solutions from
graph theoretical frameworks. These applications range from part-of-
speech tagging, word sense disambiguation, ontology learning and
parsing to information extraction, semantic role assignment,
summarization and sentiment analysis to name but a few. The emergence
of new fields of research focusing on the social media such as Twitter
and Facebook brought the graph-based methods even more into focus. In
particular, graph-based algorithms are used to explore social network
connections and propagation of information in those networks in
addition to exploring the connections between the language entities. As
a consequence, many new applications have been emerging such as rumor
proliferation, e-reputation, multiple identity detection, language
dynamics learning and future events prediction to name but a few.
TextGraphs-7 aims to bring together researchers interested in GT
applied to NLP and provide an environment for further integration of
graph-based solutions into NLP tasks. The workshop also encourages
discussions about theoretical justifications from GT that explain
empirical results obtained in the NLP community. As a consequence, a
deeper understanding of new theories of graph-based algorithms is
likely to help to create new approaches and widen the usage of graphs
for NLP applications.

(3) Important Dates
======================================================

Submission deadline: March 18, 2012
Notification of Acceptance: April 15, 2012
Camera-ready deadline: April 30, 2012
Workshop: July 12, 2012

====================================================
(4) Authors Instructions
====================================================

Submissions will consist of (1) regular full papers of maximum 8 pages
(for well established research), (2) regular short papers of maximum 4
pages (for on-going research), (3) position papers of maximum 4 pages
(for prospective ideas) and (4) demo papers of maximum 4 pages (for
software and architectures). One extra page will be accepted for the
Reference section for all submissions’ types.

Textgraphs-7 will have a blind review policy. In order to facilitate
blind reviewing, the authors should omit their names and affiliations
from the paper. Furthermore, all self-references that may reveal the
author identity must be avoided. Papers that do not conform to these
requirements will be rejected without review.

All submissions must be in PDF format and must be formatted using the
ACL 2012 Style Files available a http://www.acl2012.org/call/sub01.asp.

Papers should be submitted to the START Conference Manager available at
the following url: https://www.softconf.com/acl2012/textgraphs-7/.

=======================================================
(5) Invited Speaker
=======================================================

TextGraphs-7 will have the pleasure to invite Lada Adamic to present
her work on information propagation in blogs and tweets. Lada Adamic is
an associate professor in the School of Information at the University
of Michigan Ann Arbor. She is also affiliated with the Center for the
Study of Complex Systems and the Electrical Engineering and Computer
Science Department. Her research interests center on information
dynamics in networks: how information diffuses, how it can be found,
and how it influences the evolution of a network's structure. She
worked previously in Hewlett-Packard's Information Dynamics Lab. Her
projects have included identifying expertise in online question and
answer forums, studying the dynamics of viral marketing, and
characterizing the structure in blogs and other online communities. She
recently received the 10 years best paper award from the ACM/IEEE/WIC
Conference 2011.

==================================================
(6) Poster Session
==================================================

Authors of accepted papers and demos will be able to present their work
on a poster in addition to the oral presentation. The posters will be
displayed in the workshop room all day and there will be a short poster
session in the workshop schedule.
