Tracking emotions and opinions on certain subjects allows identifying users’ expectations, feelings, needs, reactions against particular events, political view towards certain ideas, etc. Therefore, mining, extracting and understanding opinion data from text that reside in online discussions is currently a hot topic for the research community and a key asset for industry.</div><div class="gmail_default"><br></div><div class="gmail_default">The produced discussion spanned a wide range of domains and different areas such as commerce, tourism, education, health, etc. Moreover, this comes back and feeds the Web 2.0 itself thus bringing to an exponential expansion.</div><div class="gmail_default"><br></div><div class="gmail_default">This explosion of activities and data brought to several opportunities that can be exploited in both research and industrial world. One of them concerns the mining and detection of users’ opinions which started back in 2003 (with the classical problem of polarity detection) and several variations have been proposed. Therefore, today there are still open challenges that have raised interest within the scientific community where new hybrid approaches are being proposed that, making use of new lexical resources, natural language processing techniques and semantic web best practices, bring substantial benefits.</div><div class="gmail_default"><br></div><div class="gmail_default">Computer World [1] estimates that 70%-80% of all digital data consists of unstructured content, much of which is locked away across a variety of different data stores, locations and formats. Besides, accurately analyzing the text in an understandable manner is still far from being solved as this is extremely difficult. In fact, mining, detecting and assessing opinions and sentiments from natural language involves a deep (lexical, syntactic, semantic) understanding of most of the explicit and implicit, regular and irregular rules proper of a language.</div><div class="gmail_default"><br></div><div class="gmail_default">Existing approaches are mainly focused on the identification of parts of the text where opinions and sentiments can be explicitly expressed such as polarity terms, expressions, statements that express emotions. They usually adopt purely syntactical approaches and are heavily dependent on the source language and the domain of the input text. It follows that they miss many language patterns where opinions can be expressed because this would involve a deep analysis of the semantics of a sentence. Today, several tools exist that can help understanding the semantics of a sentence. This offers an exciting research opportunity and challenge to the Semantic Web community as well. For example, sentic computing is a multi-disciplinary approach to natural language processing and understanding at the crossroads between affective computing, information extraction, and common-sense reasoning, which exploits both computer and human sciences to better interpret and process social information on the Web.</div><div class="gmail_default"><br></div><div class="gmail_default">Therefore, the Semantic Sentiment Analysis Challenge looks for systems that can transform unstructured textual information to structured machine processable data in any domain by using recent advances in natural language processing, sentiment analysis and semantic web.</div><div class="gmail_default"><br></div><div class="gmail_default">By relying on large semantic knowledge bases, Semantic Web best practices and techniques, and new lexical resources, semantic sentiment analysis steps away from blind use of keywords, simple statistical analysis based on syntactical rules, but rather relies on the implicit, semantics features associated with natural language concepts. Unlike purely syntactical techniques, semantic sentiment analysis approaches are able to detect sentiments that are implicitly expressed within the text, topics referred by those sentiments and are able to obtain higher performances than pure statistical methods.</div><div class="gmail_default"><br></div><div class="gmail_default">[1] Computer World, 25 October 2004, Vol. 38, NO 43.</div><div class="gmail_default"><br></div><div class="gmail_default"><br></div><div class="gmail_default">*** Submissions ***</div><div class="gmail_default"><br></div><div class="gmail_default">Two steps submission</div><div class="gmail_default"><br></div><div class="gmail_default">* First step:</div><div class="gmail_default"><br></div><div class="gmail_default">1.
