Emerging field of Social Informatics requires new insights into natural language processing methods. It is now more clear than ever that such topics as emotion processing, decision making and opinion mining are closely related to each other and thus should not be studied separately.

We would like to invite papers from researchers with the common interests in knowing more about ourselves and the world we live in by means of opinion and sentiment analysis, recommendations, Web mining, decision making, etc. We are also interested in gathering researchers working on emotions, psychology, sociology or ethics with Natural Language Processing tools.

We cordially invite experts, researchers and scholars in relevant fields to share their knowledge and join us in a constructive discussion on these topics.

Topics of interest include, but are not limited to:

Affect Analysis (and its applications)
Decisions and NLP
Ethics and NLP
Opinion Mining
Recommendation Systems
Sentiment Analysis
Social Informatics
Text mining techniques
Preference models
Knowledge acquisition
Pragmatics of decision making
Cognitive aspects of decisions and opinions
