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

Submission Deadline: July 12, 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*

Paper submission deadline: July 12, 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.
