The proliferation of User-Generated Content (UGC) has led to catalytic changes both in the news production process and in the journalist-audience relationship. Media organizations redesign their strategies, by adopting tools of participatory journalism through which amateurs comment on stories, submit material for publication or share articles. Furthermore, a large amount of content becomes constantly available on social media platforms, enhancing the need of continuous monitoring and effective management. However, the coexistence of professional and amateur content raises significant issues, forcing media organizations to spend resources in order to ensure quality. Except for traditional methods, modern collection, management and validation methods are often based on semantic web services. The paper aims to offer an in-depth description of the already available semantic analysis tools in the context of participatory journalism, seeking to identify the existing use of semantic technology for UGC exploitation and to propose a model for semantic annotation of UGC.
