Abstract: The “social web” provides new tools to efficiently create and share ideas with everyone connected to the World Wide Web. Forums, blogs, social networks, and content-sharing services help people share useful information. Capturing public opinion on diverse topics has garnered increasing interest from the scientific community, and from the business world. The resulting emerging fields are opinion mining and sentiment analysis. With more than 10,000 new videos posted online every day on social websites such as YouTube and Facebook, one crucial challenge for the coming decade is to be able to harvest relevant information from this constant flow of multimodal data.
Keywords: Social Web, Opinion Mining, Sentiment Analysis, Unimodal, Multimodal.
