Social Media: Fundamentals, Models, and Ranking of User-Generated Content

The increasing amount of user-generated content available on social media platforms requires new methods to find, evaluate, and to compare. To this day, existing ranking approaches to user-generated content do not allow for evaluation across platforms by exploiting its metadata. User-generated content, such as blog postings, forum discussions, shared videos etc. does however contain information that can be used for its evaluation independent of specific search interests. Claudia Wyrwoll presents a query- and language-independent ranking approach that allows for global evaluation of user-generated content across different platforms. Building on an insightful introduction into social media fundamentals, she proposes new models describing phenomena associated with social media, laying the foundation for further research and development.
