CALL FOR PAPERS

*PATHOS-2013: 2nd Workshop on Practice and Theory of Opinion
Mining and Sentiment Analysis*

workshop held in conjunction with GSCL-2013

September 23, 2013, Darmstadt, Germany

*Extended* Submission Deadline: July 26, 2013 Acceptance
notification: August 16, 2013

Website: https://sites.google.com/site/pathosworkshop/home

*Scope of the Workshop*

The abundance of opinions available on the World Wide Web
represents an information repository of enormous intellectual and
economic value. Automated methods to exploit this rich knowledge
mine have become more and more relevant within the last decade
and the availability of large amounts of data is an ideal premise
for the application of empirical methods.

Although many researchers from different nations and institutes
intensively work on the development of these techniques, many
challenges have been left uncovered: Among the highly relevant
social media are new text types, that are fairly different from
the types on which research in natural language processing has
been conducted for the last 20 years. The most prominent example
may be Twitter; with its condensed tweets it presents a
sublanguage of its own. Traditional approaches often leave
questions about the true nature of opinions unanswered. The
actual emotion hidden in opinionated text is still hard to
uncover; current lexical resources for sentiment analysis mostly
only contain information about the polarity or subjectivity of
terms, lacking relevant information of their emotional category.
Fear or anger are treated equally, as are hope and joy. Emotional
categories are projected onto two polarities, i.e. positive and
negative, which oversimplifies reality. A further important
aspect requiring methodological coverage is the exact analysis of
the entities participating in the event evoked by an opinion.
Robust linguistic techniques embedded in data-driven methods will
possibly guide the way to answer questions on the actual target
of an opinion or on the peer group holding this opinion. Another
challenge is the automated assignment of polarity or subjectivity
labels to the plethora of sentiment-related textual data readily
available on the Web. State-of-the-art learning approaches, such
as weakly-supervised or semi-supervised methods or distant
supervision still need to be thoroughly examined for this
purpose.

Another important aspect of this workshop is its focus on
multi-linguality. Therefore, submissions for approaches devised
and applied on languages other than English, in particular
German, are strongly encouraged.

The workshop aims for providing a platform for researchers
interested in the upcoming challenges of sentiment analysis and
opinion mining. It intends to attract researchers settled in
computational linguistics, natural language processing, and
artificial intelligence alike. The workshop will be organized by
the recently founded GSCL-Interest Group on German Sentiment
Analysis (IGGSA):
http://www.gscl.org/ak-stimmungsanalyse-en.html.

*Topics of Interest*

We invite contributions on, but not necessarily limited to:
- Genre- and domain-specific sentiment analysis
- Cross-genre and cross-domain sentiment analysis
- Semi-supervised/weakly supervised learning for sentiment
  analysis
- Contrast of machine learning vs. linguistic approaches vs.
  hybrid methods
- Sentiment analysis on twitter and social media in general
- Fine-to-coarse sentiment analysis
- Emotion detection and classification
- Representation of and calculus on emotions
- Multi-lingual sentiment analysis
- Lexical resources for opinion mining and sentiment analysis
- Gold standards and methods for evaluation
- Real-world applications and large-scale sentiment analysis
- Trends and perspectives in the field

*Important Dates*

*Extended* paper submission deadline: July 26, 2013 Acceptance
notification: August 16, 2013 Workshop: September 23, 2013

*Submission Guidelines*

We will accept two types of submissions: full papers and extended
abstracts. Accepted papers will be published in a special issue
of the Journal for Language Technology and Computational
Linguistics (http://www.jlcl.org). The editors-in-chief have
already approved of publishing a special issue for 2014. All
accepted full papers and extended articles qualify for an oral
presentation on the workshop. Accepted full papers also qualify
for a publication in JLCL. There will be two types of acceptances
"Accept as is" and "Accept with Revision". In the latter case, a
revised version of the paper has to be submitted which will
undergo a second review to safeguard that necessary revisions
have been sufficiently implemented. Accepted extended abstracts
will not be published in the JLCL. However, authors of selected
abstracts may be invited to submit a full paper for the journal.
That submission will also undergo an additional review. The
purpose of extended abstracts is to allow interesting work in
progress or project reports as contributions on the workshop that
are not yet ripe for publication. The submission guidelines of
this workshop (w.r.t. the format of these types of papers) will
follow the guidelines of the JLCL journal:
http://www.jlcl.org/index.php?modus=style_sheets Full papers must
not extend 12 pages (including references). Extended abstracts
must not exceed 2 pages (including references). The timeline for
the first submissions (i.e. acceptance for presentation on the
workshop) will follow the workshop timeline proposed by GSCL. The
timeline for the publication of the special issue of JLCL still
needs to be negotiated with the editorial office of JLCL.

The reviewing will be double blind. All submissions should
describe original work that has not been previously published. We
also accept demos, position papers (opinion pieces), and
submissions discussing interesting negative results.
