Workshop at ACL 2010
Association for Computational Linguistics Conference Uppsala, Sweden -

Deadline for paper submission: Monday, April 5th, 2010

TextGraphs is at its fifth edition! This shows that two seemingly
distinct disciplines, graph theoretic models to 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.

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. 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.


Special Theme: Graph Methods for Opinion Analysis
----------------------------------------------------------------

For the fifth edition of TextGraphs, we propose the special theme:
ìGraph Methods for Opinion Analysisî. This choice is motivated by two
important factors: (1) advanced opinion analysis that aims to go
beyond polarity recognition necessitates the integration of syntactic,
semantic and logic structures and (2) previous work in NLP has shown
that graph methods are very well suited to represent and exploit such
structures in learning systems.

The aim is to bring together researchers from graph theory and opinion
analysis 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 ambitious opinion analysis research and
provide a new, challenging problem motivation for research in graph
algorithms.

Finally, as the field of opinion mining advances towards deeper
analysis and more complex systems, graphical approaches may become
even more pertinent. For instance, graphs may be employed to capture
opinion dynamics over time, or to model interactions between opinion
expressions across multiple modalities and, to realize this, new
graph-based algorithms and inference methods may need to be developed.
