    An adaptive policy routing with thermal field approach
    (9th International Conference On Innovative Internet Community Systems I2CS 2022, 2009) Lertsuwanakul, Lada-On; Unger, Herwig
    This paper introduces an adaptive routing approach based on buffer status and distance in a mesh overlay network: Thermal Field is used for considering buffer stage and distance is applied to select routing policy. The path selection process considers the Thermal Field as a metaphor for the buffer usage based on probability in order to avoid message loss by overloaded peers or delay because of big queues, otherwise routing by the shortest way. In addition, the probability of Thermal Field consideration relies on leftover distance to the target instead of using a global constant. The experiment results substantiated our approach using the adaptive probability of routing mechanism works effectively.

    Bi-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
    This 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.

    Contributing and socialization – biaxial segmentation for users generatingcontent
    (9th International Conference On Innovative Internet Community Systems I2CS 2011, 2009) Send, Hendrik; Michelis, Daniel
    User 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.

    The 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.

    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.

    FacebookAgent – 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
    Over 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.

    From 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, Robert
    In 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.

    A game theoretic approach to graph problems
    (9th International Conference On Innovative Internet Community Systems I2CS 2020, 2009) Böhme, Thomas; Schreyer, Jens
    We 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.

    A hybrid approach to identifying user interests in web portals
    (9th International Conference On Innovative Internet Community Systems I2CS 2018, 2009) Bakalov, Fedor; König-Ries, Birgitta; Nauerz, Andreas; Welsch, Martin
    Web portals pioneered as one of the earliest adopters of personalization techniques to help users dealing with the problem of information overload. Nowadays they are extensively used as a single-point of access to the vast amount of resources available on the Web and in enterprise intranets. A number of researchers have been investigating the possibilities to enable portals to deliver the content in a highly-personalized manner in order to provide users with a quick and efficient access to the subset of resources relevant to their information needs. However, in order to achieve such a personalization effect, the portal needs accurate and up-to-date information about users, especially the information about their interests. In this paper, we describe a hybrid approach to identifying user interests in Web portals. In our approach, the portal is enabled to "learn" the user interests from the content of visited pages. In addition, it is empowered to provide users with an open access interface to their user models to let them explicitly specify their interests and, in case of incorrectly identified interests, outvote the portal.
