    A Brief Tutorial on How to Extract Information from User-Generated Content (UGC)
    (KI - Künstliche Intelligenz: Vol. 27, No. 1, 2013) Egger, Marc; Lang, André
    In this brief tutorial, we provide an overview of investigating text-based user-generated content for information that is relevant in the corporate context. We structure the overall process along three stages: collection, analysis, and visualization. Corresponding to the stages we outline challenges and basic techniques to extract information of different levels of granularity.

    How to Identify Successful Actors of the Flickr Community and How to Determine Their Attributes
    (INFORMATIK 2008. Beherrschbare Systeme - dank Informatik. Band 2, 2008) Egger, Marc; Fischbach, Kai; Gloor, Peter; Lang, Andre; Sprenger, Mark
    The emergence of Web 2.0 technologies has greatly enhanced capabili- ties of online social networking. Flickr is a social networking platform that enables users to share digital pictures. In contrast to other social networking sites, photos are the basic unit of information exchange in Flickr. We analyse relationships between users with a data set that covers 35% of the whole Flickr community. We define metrics of success for content, content providers, the relationship between both and identify implications of having information about successful content. We establish performance criteria and examine the correlation between the performance and the connectivity of users. Based on these key metrics we identify high quality content producers for a given category.
