********************************************************************

The rise of social media such as blogs and social networks and the
increasing amount of user-generated contents in the form of reviews,
recommendations, ratings and any other form of opinion, has led to creation
of an emerging trend towards online reputation analysis. The so-called
sentiment analysis, i.e., the application of natural language processing
and text analytics to identify and extract subjective information from
texts, which is the first step towards the online reputation analysis, is
becoming a promising topic in the field of marketing and customer
relationship management, as the social media and its associated
word-of-mouth effect is turning out to be the most important source of
information for companies and their customers' sentiments towards their
brands and products.

Sentiment analysis is a major technological challenge. The task is so hard
that even humans often disagree on the sentiment of a given text. Some
issues that one individual finds acceptable or relevant may not be the same
to others, along with multilingual aspects, cultural factors and different
contexts make it very hard to classify a text written in a natural language
into a positive or negative sentiment. And the shorter the text is, for
example, when analyzing Twitter messages or short comments in Facebook, the
harder the task becomes.

Within this context, TASS is an experimental evaluation workshop, as a
satellite event of the SEPLN 2012 Conference. It will be held on September
7th, 2012 in Jaume I University at Castellón de la Plana, Comunidad
Valenciana, Spain, to foster the research in the field of sentiment
analysis in social media, specifically focused on Spanish language. The
main objective is to promote the application of existing state-of-the-art
algorithms and techniques and the design of new ones for the implementation
of complex systems able to perform a sentiment analysis based on short text
opinions extracted from social media messages (specifically Twitter)
published by a series of representative personalities.

The challenge task is intended to provide a benchmark forum for comparing
the latest approaches in this field. In addition, with the creation and
release of the fully tagged corpus, we aim to provide a benchmark dataset
that enables researchers to compare their algorithms and systems.

Two tasks are proposed for the participants: sentiment analysis and
trending topic coverage.

*** Task 1: Sentiment Analysis ***

This task consists on performing an automatic sentiment analysis to
determine the polarity of each message in the test corpus.

*** Task 2: Trending topic coverage ***

In this case, the technological challenge is to build a classifier to
identify the topic of the text, and then apply the polarity analysis to get
the valoration for each topic.
