  Sentiment analysis systems hackathon

In the light of the fact that different sentiment analysis systems have
been proposed and showcased in the past years, we feel there is a
growing need to make other researchers and users familiar with these
systems and have them employ them for building an end application.

The Hackathon word stands for "Hacking Marathon", and its purpose is to
introduce some system and make users employ it to build an application
for a real-life task.

We would like to invite researchers who have a working prototype of
their system to announce their availability to participate in the WASSA
2014 Hackathon.

The systems can be oriented to the following tasks:

./The use of semantic resources and methods (knowledge bases, semantic
  representations, inference mechanisms) for subjectivity, sentiment and
  emotion analysis/

./Opinion retrieval, extraction, categorization, aggregation and

./Trend detection in social media using subjectivity and sentiment
  analysis techniques/

./Data linking through social networks based on affect-related NLP

./Mass opinion estimation based on NLP and statistical models/

./Online reputation management/

./Subjectivity, sentiment and emotion detection in social networks/

./Classification of stance in dialogues/

./Subjectivity and sentiment analysis in social media/

To participate with a system or as a "hacker" of one of the
participating systems, please send an e-mail to:

Alexandra.Balahur at 

In order to speed up the process, we will put the "hackers" in contact
with the system authors, so that the applications can be explored prior
to the WASSA 2014 workshop.

We will also invite papers describing the results of these experiments
as part of the final workshop.

We are looking forward to your participation!

On behalf of the WASSA 2014 Organizers,
Alexandra Balahur
