Subjectivity and sentiment analysis (opinion mining) are two tasks of growing importance in the field of Natural Language Processing (NLP). This is due to their high applicability to real-life domains – e.g. marketing, policy-making, decision-support, e-Government – but also to the fact that they improve other NLP tasks, such as Information Extraction, Information Retrieval or Question Answering.
The aim of this workshop is to bring together researchers in computational linguistics, dealing with subjectivity and sentiment analysis, but also from other disciplines related to this area: psychologists, sociologists, economists etc., with the objective of facilitating an interdisciplinary dialogue on the analysis, requirements, issues and applications of the study of subjectivity and sentiment in the context of traditional and emerging text types. We are especially interested in real-life applications, comparisons between approaches on different text types, in a monolingual or multilingual setting, joint topic and sentiment analysis, creation, annotation and evaluation of resources.

Topics of interest

We welcome original and unpublished evaluation or position papers on all subjectivity and sentiment-related issues. Some suggested topics include, but are not limited to:

• Subjectivity and opinion retrieval, extraction, categorization, aggregation and summarization
• Topic and sentiment studies and applications of topic-sentiment analysis
• Mass opinion estimation based on NLP and statistical models.
• Domain, topic and genre dependency of sentiment analysis
• Ambiguity issues and word sense disambiguation of subjective language
• Intrinsic and extrinsic evaluation methodologies
• Proposals involving the computational treatment of large amounts of data
• Pragmatic analysis of the opinion mining task
• Use of Semantic Web technologies for subjectivity and sentiment analysis
• Annotation schemes for subjectivity and corpora creation
• Improvement of NLP tasks using subjectivity and/or sentiment analysis
• Real-world applications of opinion mining systems
