- KonferenzbeitragLinking the tele-TASK video portal to the semantic web(9th International Conference On Innovative Internet Community Systems I2CS 2025, 2009) Baumann, Bert; Groß, Andreas; Meinel, Christoph; Sack, HaraldAudiovisual data have gained an enormous and ever-growing popularity in the world wide web. Also a growing number of educational content such as, e.g., lecture recordings or audiovisual learning material can be found recently. But, pinpoint and exhaustive retrieval of audiovisual e-learning content in the web is rather difficult as well as automated metadata interchange and integration. We demonstrate a use-case of metadata integration for audiovisual learning resources by complementing web pages of a video lecture portal with semantic RDFa annotations giving way to automated access and universal retrievability.
- 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, DjamshidThis 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.
- 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, AnkeOur 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.
- KonferenzbeitragFrom community towards enterprise – a taxonomy-based search for experts(9th International Conference On Innovative Internet Community Systems I2CS 2023, 2009) Eichler, Gerald; Lommatzsch, Andreas; Strecker, Thomas; Ploch, Danuta; Strecker, Conny; Wetzker, RobertIn this paper we introduce a version of the Spree expert finding framework [BAA+07] tailored for enterprises. Whereas expert finding services have been very successful on the Web, enterprise level solutions are still scarce. This comes as a surprise, as the process of finding the right person (to ask) among colleagues requires a considerable percentage of most employees' time yielding a high potential for optimization. The core of Spree is an expert finding algorithm that automatically maps questions to the most qualified experts using a domain-specific topic taxonomy as intermediate. Apart from the framework itself, we describe the challenges and design decisions that have to be taken into consideration when implementing expert finding solutions in enterprises. These include the selection of an appropriate domain taxonomy, the motivation of employees to share their knowledge and privacy related concerns.
- 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, ThierryWeb 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'.
- KonferenzbeitragA game theoretic approach to graph problems(9th International Conference On Innovative Internet Community Systems I2CS 2020, 2009) Böhme, Thomas; Schreyer, JensWe investigate some well known graph theoretic problems from a game theoretic point of view. To coloring and matching problems we associate binary payoff games where the players are the vertices of the graph. Solutions to the graph problems correspond to action profiles of the game, where all players get payoff 1. We show, that there exist rules for the choice of action in the repeated play of these games, that converge to the solution of the graph problems. Although the convergence is slow, this shows, that the problems can be solved with almost no information on the underlying graph.
- 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, IngridThe 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.
- 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.In 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.
- 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, AndreasAt 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.
- 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, AndreasUser 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.
