    Enabling social media content quality assurance using social network analysis
    (9th International Conference On Innovative Internet Community Systems I2CS 2010, 2009) Sanmateu, Maria-Amparo; Trier, Matthias; Lienicke, Andreas; Rederer, Andreas
    User Generated Content (UGC) is one of the bases of Web2.0, its quality control a critical issue. This paper describes the work done at T-Laboratories to specify and develop an innovative adaptable Quality Management System for UGC leveraging ranking, priorization and content exclusion of UGC. The Content Quality Assurance System (CQA System) is an innovative modular combination of multimedia mining aiming to serve different types of content platforms, especially those based on UGC (i.e. online communities). One of the pillar technologies used in our system is Social Network Analysis (SNA). SNA methods to calculate KPI'S between social connections and evaluated and rated content objects have been proved to provide a more complete and valued insight for content compliance, community controlling, and identification of valuable users and contents inside a community. SNA metrics propose qualitative user centered analysis of the community life cycle versus traditional volume-based measures, enabling efficient community gardening and community marketing with new innovative content management use cases. Our combination of SNA methods with traditional content mining technologies proposes enhanced identification of relevant users and content, focused intervention (incentivation), social media relevance engines, multimedia content analysis overcoming the reality of immature technologies for i.e. UGC-video. Next steps will enhance our CQA System for major communities support, and extend the concept for other content management areas.

    Socially enhanced reachability support within an IMS-community-based infrastructure solution
    (9th International Conference On Innovative Internet Community Systems I2CS 2012, 2009) Krifka Dobes, Zuzana; Lüke, Karl-Heinz; Rederer, Andreas
    At Deutsche Telekom Laboratories we are investigating how group communication can be enhanced with contextual information such as reachability. We demonstrate these methods using a group communication scenario which is of interest to us from a user and telco perspective. The scenario includes features such as messaging, presence and „click-to“ style communication, including conferencing between friends and persons with common interests. We summarize our analysis of two types of approaches to the next generation IMS platform capabilities, modular and layered approaches. We include lessons learned from our prototypes efforts, which made use of IMS capabilities. We point out some of the technical challenges that were confronted while realizing a showcase of use cases involving groups communication involving users using mobile devices and as well as users connected by web on their home PCs.

    Spree – trial-based improvements: transferring an enterprise 2.0 into a web 2.0 expert community application
    (11th International Conference on Innovative Internet Community Systems (I2CS 2011), 2011) Rederer, Andreas; Eichler, Gerald; Kury, Thomas; Schwaiger, Roland
    The Innovation Development of Deutsche Telekom Laboratories has developed a web portal for enterprise expert communities. It combines expert matching and communication functions to initiate and support domain specific online discussions. This paper describes the move from basic features of this corporate portal to a Web 2.0 instance using the results of a field trial and a usability evaluation. Following a new short term scope and integrating an innovative location mashup, the web portal was overhauled in a completely new design. The achievements also lead into comprising an architectural review and operational experiences. The conclusion contains an outlook regarding both, new innovative features and system architecture.
