- KonferenzbeitragTowards internet communities to help improve the wellbeing andrehabilitation of clinically stable chronic patients(9th International Conference On Innovative Internet Community Systems I2CS 2013, 2009) Wienhofen, Leendert W. M.; Svagård, Ingrid; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarThe EU project NEXES introduces IT support for integrated healthcare, and attempts to prove through clinical trials how new technology can help improve healthcare. The web-based approach used in the Norwegian clinical trial on wellbeing for chronically ill patients can be seen as a very small health care community for the patients. After introducing the NEXES project, the technical platform used for the wellbeing case, and the collaboration notation in BPMN, a specific case is described in detail and related to how the collaboration between the patient and health care stakeholders can be seen as a small group. Finally reflections are given on how the clinical trial could be extended by adding a 'competition' element using online communities in order to motivate the patients to do their rehabilitation exercises, and which technology standard could be used for this approach.
- KonferenzbeitragIntegrated solutions and services in public transport on mobile devices(9th International Conference On Innovative Internet Community Systems I2CS 2017, 2009) Lüke, Karl-Heinz; Mügge, Holger; Eisemann, Matthias; Telschow, Anke; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarOur society is characterised by individuality, comfort and mobility. It has been shown in many scientific studies that the mobile phone plays an important role in our living and working environment. While navigation systems in cars offer a high level of individuality, comfort and a high degree of integration with the car electronics, there are no comparable solutions and services available in public transport. In this paper, it is described that integrated solutions in public transport can improve the user needs in terms of flexibility and convenience. Although there are several individual mobile applications for rail information and ticketing available, an integrated and profile-based solution is hard to find on the market. We propose an integrative architecture that covers mobile trip planning, intelligent mobile ticketing and community solutions during the trip. This shows that our findings can enhance flexibility and comfort in public transport.
- KonferenzbeitragThe development of a personal mobile GIS(9th International Conference On Innovative Internet Community Systems I2CS 2015, 2009) Ng, Ka-Ho; Tang, Wallace K.S.; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarIn this paper, the development of a personal mobile Geographic Information System is described. The system is configured in a client-server architecture, involving mobile clients and a servicing server. With the use of Global Positioning System, the locations of a group of mobile clients are identified and these pieces of information are sent to server for additional services. For demonstration, the system is used as a real-time location tracking system. It not only provides the tracking of the users, but also serves as a monitoring system for issuing emergency call, whenever an abnormal scenerio is identified. These designs well illustrate how the mobile and Internet technologies can be used to enhance this kind of applications. The same framework has also been extended for fleet management to demonstrate its potential applications in logistics industry.
- KonferenzbeitragEnabling 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; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarUser 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.
- KonferenzbeitragSocially 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; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarAt 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.
- KonferenzbeitragFacebookAgent – an agent-enhanced social (mobile) network application(9th International Conference On Innovative Internet Community Systems I2CS 2016, 2009) Schau, Volkmar; Erfurth, Christian; Pasold, René; Rossak, Wilhelm; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarOver the past years, a new kind of understanding and utilization of Internet services has emerged. People successfully form online communities and contribute actively. Facebook is one example for such an online social network (OSN) which has attracted millions of Internet users within a very short time period. In this paper we follow the idea to expand the virtual world spanned by OSNs into the user's real world. To achieve this goal, we apply the mobile agent paradigm as a connector concept to strengthen the integration of users. As an example for OSNs we rely on Facebook.

- KonferenzbeitragBi-directional distribution of elearning content for cross-technology learning communities(9th International Conference On Innovative Internet Community Systems I2CS 2014, 2009) Zender, Raphael; Dressler, Enrico; Lucke, Ulrike; Tavangarian, Djamshid; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarThis article describes the use of a service-oriented architecture to bridge the gap between different eLearning types and tools. The basic concept is a bi-directional distribution of web services provided by different eLearning environments. This is exemplarily verified by a combination of lectures that are held in a modern media supported lecture room with tools of the computer-aided face-to-face learning paradigm and within a virtual learning environment (Second Life). The new service-based approach allows a flexible and systematic coupling of virtual and face-to-face teaching and learning to a cross-technology learning community.
- KonferenzbeitragContributing and socialization – biaxial segmentation for users generatingcontent(9th International Conference On Innovative Internet Community Systems I2CS 2011, 2009) Send, Hendrik; Michelis, Daniel; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarUser generated content is a valuable resource voluntarily provided by a growing number of users. As online and traditional businesses increasingly harness this resource the need for a strategic way to manage users has become apparent. In this paper, we seek to establish a model that applies prior research insights regarding user behaviour to user generated content. Therefore, we develop a strategic segmentation of users who contribute content. Using a biaxial model put forward by Kozinets for the segmentation of consumers and an ordinal scale model by Li and Bernoff, we propose a model to grasp both the degree of social involvement and the intensity of content contribution by users.
- KonferenzbeitragPersonal and collective knowledge management in the web 2.0: Two faces of knowledge management?(9th International Conference On Innovative Internet Community Systems I2CS 2009, 2009) Kirchner, Kathrin; Razmerita, Liana; Nabeth, Thierry; Erfurth, Christian; Eichler, Gerald; Schau, VolkmarWeb 2.0 has reinvented the concept of Knowledge Management towards a vision aiming at faciliating interaction, cooperation and knowledge exchange of individuals, groups and communities. This article tries to answer two questions: Can Web 2.0 tools be applied for managing knowledge at the individual and collective level? and How effective are Web 2.0 tools for supporting Personal Knowledge Management? After introducing the comcept of Personal Knowledge Management (PKM), Collective Management (CKM) and Web 2.0 phenomenon, this paper surveys different Web 2.0 tools and compare their role for supporting CKM and PKM. The conclusion of this study appears to confirm that the individual and collective dimension are not conflicting, but on the contrary represent two different facets of complex knowledge management process. Furthermore this study indicates a number of pitfalls such as: the level of complexity and fragmentation of these tools makes the optimal usage difficult, or/and the privacy risks that originates from the difficulty to separate the 'personal sphere' from the 'collective sphere'.
