SEPLN 2016 workshop on:

Sentiment Analysis at SEPLN (TASS 2016)

Sep 13th, 2016 Salamanca, Spain


Registration: http://www.sepln.org/workshops/tass/2016/tass2016.php#contact


TASS is an experimental evaluation workshop for sentiment analysis and online reputation analysis focused on Spanish language, organized as a satellite event of the International Congress of SEPLN. After three successful editions in 2012, 2013, 2014 and 2015, TASS 2015 will be held on September 15th, 2015 at University of Alicante, Spain.

The aim of TASS is to provide a forum for the discussion and communication where the latest research work and developments in the field of sentiment analysis in social media, specifically focused on Spanish language, can be shown and discussed by scientific and business communities. The main objective is to promote the application of existing state-of-the-art algorithms and techniques and the design of new ones. These complex sentiment analysis and text classification systems will work with short text opinions extracted from social media messages (specifically Twitter).

Several challenge tasks are proposed with the aim of providing a benchmark forum for comparing the latest approaches in these fields. 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 to the participants covering two different levels of analyses.

*** Task 1: Sentiment Analysis at global level ***

This task consists on performing an automatic sentiment analysis to determine the global polarity of each message in the test set of the General corpus. This task is a rerun of the task in the previous years. Participants will be provided with the training set of the General corpus so that they may train and validate their models.

There will be two different evaluations: one based on 6 different polarity labels (P+, P, NEU, N, N+, NONE) and another based on just 4 labels (P, N, NEU, NONE).

Participants are expected to submit (up to 3) experiments for the 6-labels evaluation, but are also allowed to submit (up to 3) specific experiments for the 4-labels scenario.

Accuracy (correct tweets according to the gold standard) will be used for ranking the systems. Precision, recall and F1-measure will be used to evaluate each individual category.

*** Task 2: Aspect-based sentiment analysis ***

Participants will be provided with a corpus tagged with a series of aspects, and systems must identify the polarity at the aspect-level. Training and test sets for one corpus will be provided: STOMPOL corpus.

Important note: The delay of the call of TASS2016 was due to the interest in working with a new general corpus. This new general corpus has passed through all stages in their development, filtering and manual labeling, but premilinar evaluation has not been satisfactory and the TASS2016 organization has chosen to work in 2016 with the same general corpus of previous editions.
