Social media mining differs from traditional data mining in many ways, offering unique opportunities to advance data mining. It consists of massive amounts of user-generated content and extensive networked data. As detailed in our latest textbook “Social Media Mining: An Introduction”, we face novel challenges such as “the evaluation dilemma” and “the noise removal fallacy”. We will introduce these challenges and present some recent research issues we encounter – a big-data paradox unique to social media where many social networking sites are present but only minimum information is available, and whether distrust is relevant and useful in social media mining. We will exemplify the intricacies of social media data, and show how to exploit unique characteristics of social media data in developing novel algorithms and tools for social media mining.
