Preface to the Second Edition
This book presents the state-of-the-art in research and empirical studies in the field of Natural Language Processing (NLP) for the semantic analysis of social media data. Because the field is continuously growing, this second edition adds information about recently proposed methods and their results for the tasks and applications that we covered in the first edition.
Over the past few years, online social networking sites have revolutionized the way we communicate with individuals, groups, and communities, and altered everyday practices. The unprecedented volume and variety of user-generated content and the user interaction network constitute new opportunities for understanding social behavior and building socially intelligent systems.
Much of the research on social networks and the mining of the social web is based on graph theory. That is apt because a social structure is made up of a set of social actors and a set of the dyadic ties between these actors. We believe that the graph mining methods for structure and information diffusion or influence spread in social networks need to be combined with the content analysis of social media. This provides the opportunity for new applications that use the information publicly available as a result of social interactions. Adapted classic NLP methods can partially solve the problem of social media content analysis focusing on the posted messages. When we receive a text of less than 10 characters, including an emoticon and a heart, we understand it and even respond to it! It is impossible to use NLP methods to process this type of document, but there is a logical message in social media data based on which two people can communicate. The same logic dominates worldwide, and people from all over the world use it to share and communicate with each other. There is a new and challenging language for NLP.
We believe that we need new theories and algorithms for semantic analysis of social media data, as well as a new way of approaching the big data processing. By semantic analysis, in this book, we mean the linguistic processing of the social media messages enhanced with semantics, and possibly also
