- KonferenzbeitragMaking money out of innovative communities on the Internet(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Arnøy, Tom; Auran, Per GunnarOnline advertising has been around for more than a decade, and today most Internet users are familiar with the contextual ad targeting in online search, of which Google AdWords is a dominant example. The pay per click model (PPC) introduced by Goto.com (later Overture) in 1998 has been the main revenue model since Google adopted it in 2002, but the advertising industry is under increasing pressure to find a better alternative model as the conversion rate for ad clicks to actual purchase is very low. There is a huge potential for improving the experience as seen from both, advertiser, publisher and end user point of view. Enter the cost per install model where advertising cost is directly tied to the response of potential customers. While this reduces risk for advertiser spending, it demands precise customer targeting to create added value for the end user and secure revenue for the publisher. The authors present a system for content-based targeting where the user behaviour within Zedge’s massive mobile community is the core signal for segmenting users into preference groups that are used for targeted advertisements. Large scale clustering using Hadoop and machine learning is combined to optimize the performance.
- KonferenzbeitragIntegrating the individual vehicle in the transport system using open services in a distributed architecture(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Moseng, Tor K.; Natvig, MaritRoad traffic management has traditionally been targeted through control and monitoring of the flow of vehicles, using the same measures towards all vehicles. As vehicles can have very different capabilities and profiles, it is however desired to use different control strategies towards the individual vehicles to meet the environmental, safety and efficiency targets for the future. SMARTFREIGHT has developed a holistic control and monitoring tool for managing the traffic, and individual vehicles in particular. The individual vehicle is integrated with the traffic management and freight distribution management centers by using open service interfaces for an interoperable information exchange between distributed systems across a heterogeneous wireless infrastructure. SMARTFREIGHT realized and successfully demonstrated this integration in its final event in Trondheim.
- KonferenzbeitragSemantic search – adaptation of knowledge models(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Tomassen, Stein L.Search applications have for many become part of their daily tools, empowering the users with easy access to vast amount of information. Despite the commonality with these tools finding quality information can still be both tedious and frustrating often involving multiples queries and analysis of extensive amounts of information. Semantic search is believed to solve many of the shortcomings found with current search applications, but still not commonly used. Semantic search has been a research area for a while, yet there are many issues to solve and improvements to make. In this talk, the author will present a variety of semantic search systems that focus on adaptation of knowledge models. The author will present different approaches for how knowledge models can be enriched or created for a domain and how they can be used in search to increase the user experience.
- KonferenzbeitragSimulation of rescue forces communities in mass causality incident situations(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Schau, Volkmar; Kirchner, Kathrin; Späthe, Steffen; Scharf, Sebastian; Hellfritzsch, Stefan; Eichler, Gerald; Erfurth, Christian; Rossak, Wilhelm; Reichel, JensMass Casualty Incident (MCI) situations require high flexibility from the involved rescue forces, including an increased need for efficient communication in sparse mobile ad-hoc networks. Simulations help to understand the performance of information flooding in these situations, to identify critical gaps in the infrastructure and to develop professional models. Based on resources, described as profiles, roles of community members can then be assigned more flexible. The presented approach and the thereupon aligned simulation provide a technological basis for developing a decision support system. This system can - before or during an MCI situation - provide support in mitigating risks. This will be achieved by executing (simulating) and comparing different alternatives to manage the situation at hand.
- KonferenzbeitragCreation and management of community-specific knowledge domain taxonomies(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Eichler, Gerald; Schwaiger, RolandThe semantic understanding of domain-specific terminology typical for communities, like a scientific conference, requires both, the analysis of daily spoken and written language in documents. A living taxonomy can help to cluster knowledge and classify questions against it, as well as to build up profiles of expertise. Text analysis modules support the parsing of training materials to extract a significant set of key phrases. However, the creation of a balanced categorisation tree requires the experience of community members. The Spree project introduces an OntoEditorTM to optimize automatic and manual processes to setup an expert finding & communication application, following well-known Web 2.0 paradigms.
- KonferenzbeitragCo-living social community for elderly(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Mathisen, Bjørn Magnus; Kofod-Petersen, Anders; Olalde, IdoiaWith a rapidly increasing elderly population, keeping elderly healthy is more important than ever. Physical and social activity is closely related to people's well-being. This paper describes some of the challenges faced when activating elderly people in an organised fashion. We propose a Virtual Collaborative Social Living Community for Elderly; utilising friends, family and care-professionals connected to the elderly in achieving this goal. Challenges related to this work in progress is then presented. The paper presents experiences made in an ongoing development and deployment of a socio-technical system.

- KonferenzbeitragDetecting source topics by analysing directed co-occurrence graphs(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Kubek, Mario; Unger, HerwigThis paper describes a new method to determine the sources of topics, that influence the main topics in texts, by analysing directed co-occurrence graphs using an extended version of the HITS algorithm. Additionally, this method can be used to identify characteristic terms in texts. In order to obtain the needed directed term relations the notion of term association is introduced to cover asymmetric reallife relationships between concepts and it is described how they can be calculated by statistical means. In the experiments, it is shown that the detected source topics and the characteristic terms can be used to find similar documents and documents that mainly deal with them in large corpora like the World Wide Web. In doing so iteratively, it is possible to easily follow topics by analysing documents from these corpora using this method. This way, users can be offered this new search function in interactive search systems that goes beyond a simple presentation of similar documents. This application will be elaborated on as well.
- KonferenzbeitragA multiple platform approach to building a bus route information system for mobile devices(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Andersstuen, Runar; Engell, Trond Bøe; Sætre, Rune; Gambäck, BjörnThe paper describes a multiple platform-based approach to creating a bus route information system for mobile devices. The system is context aware: users only need to tell the system (in natural language) where they wish to go, and the system takes care of the rest. The users are presented with a list of possible routes they can take to reach their desired destination. The results are also shown on a map that makes finding the bus stops very easy. In order to make the system available to as many users as possible, the architecture is client-server-based and relies on technology standards that are widely accepted and implemented, making it easily adaptable to new platforms. The application can be run on multiple platforms, with a minimal amount of calculations needed on the client side. The amount of data transfer between server and client is also kept to a minimum. The ability to run on multiple different platforms is achieved using technology such as HTML5, PhoneGap and Sencha Touch. The client's functionality includes a search function and a map view, as well as the ability to use bookmarks. The server handles most of the business logic and communicates with external services such as the natural language processing back-end and the server for real-time bus departure information updates.
- KonferenzbeitragLazy disclosure – mixing cloud and local storage(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Bouck-Standen, David; Cassens, Jörg; Herczeg, MichaelThe use of multiple computer systems by a single user makes data transfer a necessity. Cloud storage solutions provide synchronisation features and file accessibility across systems but the exact location and type of storage varies between services. Many systems rely on a client-server architecture where the data is held at the data centers of the service provider. This leads to several difficulties for the end user, for example with regard to privacy or data security. This is countered by the convenience of highly available servers. If the user wants to minimise exposure to the challenges of Cloud-based services, then he is required to either host a server infrastructure himself or to rely on inconvenient on-demand synchronisation by means of file transport protocols or even physical storage devices. The approach presented here tries to harvest the positive aspects of using Cloud-based services while keeping the user in control of his data. To this end, we focus on a hybrid system of a client-server and a peer-to-peer architecture which expands the Cloud to the user's system giving him full control over which data he selects to be stored on a server in the Cloud and which data he prefers to keep private on personal computing devices while ensuring unified access to both types of storage over the network.
