Meeting Description:
The aim of the MultiStanceCat task is to detect the author's stance (in favor,
against or neutral) with respect to the Catalan #1Oct Referendum (2017) in
tweets written in Spanish and/or Catalan from a multimodal perspective. This
is a multimodal task because both the text of the tweet and the information
included in the link (when this information occurs) will be taken into account
when determining the stance.
Stance detection is a task related to sentiment analysis, but unlike the
latter, in which the systems detect the positive, negative or neutral polarity
of the text, in stance detection the systems detect whether a text is
favorable or unfavorable to a topic of discussion, which is usually
controversial, and which may or may not be explicitly mentioned in the text.
The stance detection task is also related to a textual inference task due to
the fact that the position of the tweeter is often expressed implicitly,
therefore, the stance has to be inferred in many cases. Stance detection is
particularly interesting for studying political debates in which the topic is
controversial. Therefore, for this task we have chosen to focus on a specific
political issue: the Catalan #1Oct Referendum (2017).
In the training phase, participants will be provided with the TW-1OReferendum
training corpus manually annotated with stance. The possible stance labels
are: ‘favor’, ‘against’ and ‘neutral’. Later, the unlabeled test data will be
released. After the assessment, labels for the test data will also be
released.
There will be a session at IBEREVAL where the results of this shared task will
be discussed and the teams involved will present their results.
