- 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.
- 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.
- 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.
- KonferenzbeitragContext-awareness and real-time information in an intelligent smartphone application(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Marcussen, Christoffer Jun; Eliassen, Lars Moland; Sætre, Rune; Gambäck, BjörnWith the constant increase in smartphone sales, integrated sensors and map navigation have now become available to the average user. This allows for mobile applications to use context-awareness to provide more relevant information. An interesting use-case for such applications is a route information system for buses. The paper describes an application which interfaces over a mobile phone to Bus- TUC, a natural language-based reasoning-system for bus routes in Trondheim. By combining user context, BusTUC reasoning and real-time data from the bus service provider, the user-interaction is simplified, compared to a standard information system. We discuss issues on supporting context-awareness and real-time information in this system, comparing it to other available route information systems. Feedback from beta-testers indicates that the application suits the needs of typical bus travellers well.
- 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.

- KonferenzbeitragSharing personal symbolic locations between friends - a location service for small communities(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Roth, JörgIn this paper we introduce a novel community service based on personal symbolic locations. Users can share their location with other people using simple textual distribution mechanisms without the need of a geographic map display service. Small communities can set up a light-weight infrastructure and do not need to send private locations to big central service centres.
- KonferenzbeitragSocial network for elderly(12th International Conference on Innovative Internet Community Services (I2CS 2012), 2012) Gulbrandsen, Simen Kind; Fikkan, Eirik; Grunt, Emil; Mehl, Kjetil; Shamsolketabi, Safoura; Singh, Jaspreet; Vrucinic, Miso; Mathisen, Bjørn Magnus; Kofod-Petersen, AndersElderly's health is closely related to their level of social activity. Maintaining an active social life contributes to peoples' ability to live at home longer and enjoy an active and healthy life. Yet, as age progresses maintaining and expanding a social network can be challenging. The work presented here demonstrates a design and implementation of a social network system for elderly, including a recommender system, which will recommend relevant cultural and social events, and friends and acquaintances to enjoy these events with.
- 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.
- 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.
