Modeling Content Evolution in User Generated Content
Yu Wang, Department of Mathematics and Computer Science

User generated content (UGC) is usually considered as content produced by general public and made publicly available over the internet. The definition of UGC covers a wide range of popular modern websites, such as Wikipedia, Social Media Sites, and blogging services etc. Unlike traditional static webpages, UGC is often featured with content evolution over time. For instance, the content of Wikipedia articles grows as contributors collaboratively edit the pages; Users in Twitter post various topics into their Tweet streams. The distinct evolving characteristic of UGC brings challenges to traditional static models for retrieval and data mining. In this talk, we introduce novel techniques which are designed to capture and make use of the content dynamics in UGC, to better understand the evolving process and facilitate applications.
