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:

Prof. Dr. Jonathan Gratch - University of Southern California 

(tentative) Title of the talk:"Emotion theories, models and their relevance to 
sentiment analysis" 

*** Submissions:

Submissions for WASSA 2.011 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 (plus a 
maximum of 2 pages for references). WASSA 2.011 also accepts papers presenting 
system demonstrations. 

Each demo paper will have four (4) pages allocated in the proceedings (plus 
maximum one page for references). 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
