***** 2nd Workshop on Computational Approaches to Subjectivity and
Sentiment Analysis (WASSA 2.011) *****

* held in conjunction with ACL- HLT 2011, June 24, Portland, Oregon

Recent years have marked the beginning and expansion of the Social
Web, in which people freely express and respond to opinion on a whole
variety of topics. While the growing volume of subjective information
available allows for better and more informed decisions of the users,
the quantity of data to be analyzed imposed the development of
specialized Natural Language Processing (NLP) systems that
automatically detect subjectivity in text and subsequently extract,
classify and summarize the opinions available on different topics.
Although these research fields have been highly dynamic in the past
years, dealing with subjectivity in text has proven to be a complex,
interdisciplinary problem that remains far from being solved.

Inspired by the objectives we aimed at in the first edition of this
workshop and the final outcome, the purpose of WASSA 2.011 is to
create a framework for presenting and discussing the challenges
related to subjectivity and sentiment analysis in NLP, from a
theoretical and practical point of view. Moreover, taking into account
that subjectivity-related phenomena have also been studied by other
disciplines, such as Psychology, Philosophy, Economics, with WASSA
2.011 we would also like to open the door to an interdisciplinary
dialogue on the nature, implications and applications of the topic(s)
discussed. We envisage WASSA as a forum to discuss the achievements
obtained so far and to analyse the different approaches to tackle the
difficulties researchers are confronted with in this research area.


*** Topics of interest:

We encourage researchers to submit evaluation or position papers on
topics including, but not restricted to:

* Affect, emotion, feeling, subjectivity, sentiment – concept
  definition and related NLP tasks;
* Resources for subjectivity and sentiment analysis;
* Subjectivity and opinion retrieval, extraction, categorization,
  aggregation and summarization;
* Topic and sentiment studies and applications of topic-sentiment
  analysis;
* Mass opinion estimation based on NLP and statistical models;
* Domain, topic and genre dependency of sentiment analysis;
* Ambiguity and word sense disambiguation of subjective language;
* Proposals involving the computational treatment of large amounts of
  data;
* Pragmatic analysis of the opinion mining task;
* Use of Semantic Web technologies for subjectivity and sentiment
  analysis and/or emotion detection;
* Improvement of NLP tasks using subjectivity and/or sentiment analysis;
* Adaptation of traditional tasks to the opinion scenario: opinion IR,
  QA, summarization;
* Intrinsic and extrinsic evaluation methodologies;
* Real-world applications of opinion mining systems.

We also encourage participants to provide demos of their systems, thus
giving them the opportunity to obtain feedback on their achievements
and issues. At the same time, with the help of demos, we aim at
enriching the discussion forum with application-specific topics for
debate.

*** Invited Speaker:

*** Submissions:

Submissions for WASSA 2010 must not exceed eight (8) pages without
references in camera-ready format. Over-length submissions will be
rejected without review. Papers for WASSA should be submitted using
the ACL-HLT 2011 Style Files, available at:
http://www.acl2011.org/call.shtml#submission

Each accepted paper will be allocated eight (8) pages in the
proceedings. WASSA 2.011 also accepts papers presenting system
demonstrations. Each demo paper will have four (4) pages allocated in
the proceedings. They must follow the same formatting guidelines as
full papers.

Reviewing for WASSA 2.011 will be blind: reviewers will not be
presented with the identity of paper authors. Authors should avoid
writing anything that makes their identity obvious in the text.

Submissions should be original, and in particular should not
previously have been formally published.

Accepted papers will be published in the ACL WASSA proceedings, as
well as a CD with ISBN. The best papers will be chosen for a special
issue of an ISI- indexed journal.


*** Important dates:

Paper due date: March 15, 2011
Notification of acceptance: April 20, 2011
Camera-ready deadline: May 06, 2011
