Preface
The present proceedings contain the papers and invited talk presented at PATHOS-2012, the First
Workshop on Practice and Theory of Opinion Mining and Sentiment Analysis. PATHOS-2012 took
place on September 21, 2012 in Vienna Austria, in conjunction with KONVENS-2012. Its goal was
to provide a platform for researchers and developers in sentiment analysis and opinion mining to
present their ongoing work, discuss open issues in the research area and address future challenges.
PATHOS-2012 was initiated by IGGSA, the Interest Group on German Sentiment Analysis
(iggsa.sentimental.li).
We proposed the following topics in the call for papers of the workshop:
Semi-supervised/weakly supervised learning for sentiment analysis
Contrast of machine learning vs. linguistic approaches vs. hybrid methods
Sentiment analysis on twitter and social media in general
Fine-to-coarse sentiment analysis
Emotion detection and classification
Representation of and calculus on emotions
Multi-lingual sentiment analysis
Lexical resources for opinion mining and sentiment analysis
Evaluation gold standards and evaluation methodologies
Real-world applications and large-scale sentiment analysis
Trends and perspectives in the field
We received 12 submissions (7 long papers and 5 short papers) out of which we accepted 8 papers (5
long papers and 3 short papers). 4 of the submissions came from Germany, 3 from France, 2 from
Switzerland and one each from the Czech Republic, Denmark and Italy. The high number of these
international submissions underlines the significance of sentiment analysis in natural language
processing.
In addition to the presentation of the technical papers, the workshop also included an invited talk
given by Carlo Strapparava on Emotions and Creative Language.
We would like to thank the authors of the papers for their interesting contributions, the members of
the program committee for their insightful reviews, and the presenter of our invited talk, Carlo
Strapparava, for accepting the invitation to give a talk at the workshop. We also thank our Gold
Sponsor TrendMiner (www.trendminer-project.eu) and our Silver Sponsor WebLyzard
(www.weblyzard.com), who provided financial support crucial for the success of PATHOS-2012.
Eventually, we are also grateful to the organizers of KONVENS-2012 to support us at the different
stages of organizing this workshop.
