    CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap2008Annet (Annet vitenskapelig)
    Abstract [en]

    After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges.

    Preparation and analysis of multiple source industrial process data2005Rapport (Annet vitenskapelig)
    Abstract [en]

    Industrial process data is often stored in a wide variety of formats and in several different repositories. Efficient methodologies and tools for data preparation and merging are critical for efficient analysis of such data. Experience shows that data analysis projects involving industrial data often spend the major part of their effort on these tasks, leaving little room for model development and generating applications. This paper identifies and classifies the needs and individual steps in data preparation of industrial data. A methodology for data preparation specifically suited for the domain is proposed and a practically useful set of primitive operations to support the methodology is defined. Finally, a proof of concept data preparation system implementing the proposed operations and a scripting facility to support the iterations in the methodology is presented along with a discussion of necessary and desirable properties of such a tool.

    A joint statistical and symbolic anomaly detection system: Increasing performance in maritime surveillance2012Inngår i: 15th International Conference on Information Fusion, FUSION 2012, 2012, s. 1919-1926, artikkel-id 6290535Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The need for improving the capability to detect illegal or hazardous activities and yet reducing the workload of operators involved in various surveillance tasks calls for research on more capable automatic tools. To maximize their performance, these tools should be able to combine automatic capturing of normal behavior from data with domain knowledge in the form of human descriptions. In a proposed Joint Statistical and Symbolic Anomaly Detection System, statistical and symbolic methods are tightly integrated in order to detect the majority of critical events in the situation while minimizing unwanted alerts. We exemplify the proposed system in the domain of maritime surveillance.

    Edited Adaptive Hypermedia: Combining Human and Machine Intelligence to Achieve Filtered Information1997Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We discuss a novel approach to filtering of hypermedia information based on an information broker and user environment coupled together. The advantage of the proposed approach, edited adaptive hypermedia, is that it combines human expertise with machine intelligence in order to achieve high quality of the filtered information provided to the end users.

    Data Driven Maintenance: A Promising Way of Action for Future Industrial Services Management2022Inngår i: Lecture Notes in Mechanical Engineering, Springer Science and Business Media Deutschland GmbH , 2022, s. 212-223Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Maintenance and services of products as well as processes are pivotal for achieving high availability and avoiding catastrophic and costly failures. At the same time, maintenance is routinely performed more frequently than necessary, replacing possibly functional components, which has negative economic impact on the maintenance. New processes and products need to fulfil increased environmental demands, while customers put increasing demands on customization and coordination. Hence, improved maintenance processes possess very high potentials, economically as well as environmentally. The shifting demands on product development and production processes have led to the emergency of new digital solutions as well as new business models, such as integrated product-service offerings. Still, the general maintenance problem of how to perform the right service at the right time, taking available information and given limitations is valid. The project Future Industrial Services Management (FUSE) project was a step in a long-term effort for catalysing the evolution of maintenance and production in the current digital era. In this paper, several aspects of the general maintenance problem are discussed from a data driven perspective, spanning from technology solutions and organizational requirements to new business opportunities and how to create optimal maintenance plans. One of the main results of the project, in the form of a simulation tool for strategy selection, is also described.

    CHORUS Deliverable 4.3: Report from CHORUS workshops on national initiatives and metadata2007Annet (Annet vitenskapelig)
    Abstract [en]

    Minutes of the following Workshops: • National Initiatives on Multimedia Content Description and Retrieval, Geneva, October 10th, 2007. • Metadata in Audio-Visual/Multimedia production and archiving, Munich, IRT, 21st – 22nd November 2007 Workshop in Geneva 10/10/2007 This highly successful workshop was organised in cooperation with the European Commission. The event brought together the technical, administrative and financial representatives of the various national initiatives, which have been established recently in some European countries to support research and technical development in the area of audio-visual content processing, indexing and searching for the next generation Internet using semantic technologies, and which may lead to an internet-based knowledge infrastructure. The objective of this workshop was to provide a platform for mutual information and exchange between these initiatives, the European Commission and the participants. Top speakers were present from each of the national initiatives. There was time for discussions with the audience and amongst the European National Initiatives. The challenges, communalities, difficulties, targeted/expected impact, success criteria, etc. were tackled. This workshop addressed how these national initiatives could work together and benefit from each other. Workshop in Munich 11/21-22/2007 Numerous EU and national research projects are working on the automatic or semi-automatic generation of descriptive and functional metadata derived from analysing audio-visual content. The owners of AV archives and production facilities are eagerly awaiting such methods which would help them to better exploit their assets.Hand in hand with the digitization of analogue archives and the archiving of digital AV material, metadatashould be generated on an as high semantic level as possible, preferably fully automatically. All users of metadata rely on a certain metadata model. All AV/multimedia search engines, developed or under current development, would have to respect some compatibility or compliance with the metadata models in use. The purpose of this workshop is to draw attention to the specific problem of metadata models in the context of (semi)-automatic multimedia search.

    Questions, inspiration, feedback, and contributions: How entrepreneurs network online2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This work investigates how entrepreneurs use social networking sites for business. Through surveys, online discussions and interviews, we have looked at activities, motives for participating on networking sites for business, motives for contributing, and differences between online and offline networking. Our results show that networking, facts finding, and marketing are very common activities while sharing of experience is quite rare. Entrepreneurs connect with new people online rather than reifying offline networks. A novel use of social media is that of small businesses using Facebook as a web hotel. We believe that an important explanation to our results is that social media are still informal and not yet incorporated in traditional work routines.

    On the design of television as a service based on average TV watching2010Rapport (Annet vitenskapelig)
    Abstract [en]

    Ten households were interviewed about their TV watching to inform the design of TV services. Our participants were average TV viewers who had Internet access but were not technically advanced or frequent users of the Internet as a source for TV material. We found that the flow of programs that broadcast television brings to viewers was the most important motivation for our participants to turn to the TV on-demand possibilities they had access to. Examples of triggers were social cues from people talking about things seen on TV, or time-shifting issues such as missing all or part of programs in the broadcast flow. Special interests such as sports were also a strong motivation for on-demand behavior. For the viewers, linear and on-demand TV watching was intertwined. We conclude that on-demand services should be integrated with broadcast TV in the design of future TV services.

    Super Service Technician Slutrapport2015Rapport (Annet vitenskapelig)
    Abstract [sv]

    Projektet var ett kortprojekt med syfte att kartlägga och identifiera båda befintliga och nya innovativa tekniker och arbetssätt för ett resurseffektivt underhåll med minimal tidsåtgång. I projektet användes fjärrvärmebranschen och Mälarenergis nya kraftvärmeverk som en fallstudie. Projektets konstellation bestod av Mälarenegi, Sigholm Konsult, ABB Corprate Research och Dynamate IS, SICS Swedish ICT deltog som forskarpart.

    Projektet började med arbetsstudier på Mälarenergi hos gruppen ELIN, underhållstekniker inom el och instrument. Arbetsstudien bekräftade att mycket tid går åt till icke värdeskapande arbete (t.ex. leta efter dokumentation och platser) och visar även att det finns många konstruktiva förslag som skulle kunna förbättra möjligheterna att effektivisera aktiviteterna som föregår och följer underhållet. Dessutom skulle detta ha stor inverkan på arbetsmiljön för serviceteknikerna. Lågkvalitativ, otillgänglig och motstridig information är en källa till frustration. Förslag som leder till enkla sätt att lämna över, hitta och sprida information kan alltså ur flera perspektiv förbättra effektiviteten inom underhållsarbetet.

    Arbetsstudien och de uppföljande intervjuerna har utgjort grunden för analys och diskussion kring arbetssätt, problem, behov och eventuella tekniska stöd. Resultatet av analysen visas i bilaga 1. Två mindre demostratorer utvecklades också under projektets gång som inspiration och diskussionsunderlag. Båda demonstratorerna avser stöd för inhämtning av information, med utgångspunkt från ett objekt-id och från en arbetsorder.

    Mälarenergis nya panna är väl anpassad till digitaliseringen, till exempel är flertalet mätare och instrument utrustade med maskinläsbara objekt-id:n i form av QR-koder. Projektet har därför utvecklat en demonstrator i form av en smartphone-app som läser en QR-kod och visar information från många olika källor om aktuellt objekt. Appen simulerar uppkoppling till en stor mängd system för att hämta information; i realiteten finns information för ett fåtal objekt lagrad i själva appen. För den interaktiva designstudien gjordes en ”pappersdemonstrator” för att diskutera hur man på ett enkelt sätt skulle kunna presentera historisk information över tidigare utfört underhåll. Pappersdemonstratorn utgår ifrån att teknikern har fått en arbetsorder och har behov att reda på vilket arbete som utförts tidigare på det aktuella objektet. Vidare, den 3D-modell som tagits fram under planering och uppförande av block 6 bedömdes vara en möjlig resurs när det gäller att stödja underhållstekniker i att orientera sig i anläggningen och snabbare hitta fram till objekt som ska åtgärdas.

    Arbetet kring Mätetal arbetspaket har inkluderat intervjuer med fyra personer på olika nivåer i organisationen, och fått ta del av dokumentation kring hur mätetal är upplagda på Mälarenergi. Mälarenergi är i ett skede just nu där tidigare satsningar på mätetal har stagnerat och enheten planerar ett omtag med både omorganisation och införande av nya mätetal och styrning. Framtida forskning kopplat till verksamhetens utmaningar kan vara exempelvis genom användning av Kanban och andra metoder som syftar till att göra arbetslaget mer medvetna om hur flödet av uppgifter ser ut, och som förenklar kommunikation kring vilka som kan tänkas behöva hjälp och vart flaskhalsarna finns. Projektet var ett projekt inom strategiska innovation program Piia, www.sip-piia.se. Programmet PiiA representerar en nationell kraftsamling inom Processindustriell IT och Automation finansierat av VINNOVA tillsammans med Energimyndigheten och Formas.

    Co-Construction of Hybrid Spaces2005Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    When computational systems become increasingly mobile and ubiquitous, digital information and the use of computational systems may increasingly be immersed into the physical and social world of objects, people and practices. However, the digital, physical and social materials that make up these hybrid spaces have different characteristics and are hard to understand for users. In addition, users are themselves part in constructing and re-constructing the hybrid spaces. The main question addressed in this thesis is whether making aspects of the digitally mediated hybrid spaces observable and accessible provides support to users. The observability may provide support for the specific task at hand or help in building an understanding for what the system does and how, an understanding that is needed to explain system output and to cope with service breakdowns. The fundament of the approach is to empower users of computational systems to actively make sense of the system themselves. Two prototype services are described, Socifer and MobiTip. Their common denominator was to make digitally mediated parts of the hybrid spaces observable to users. Without disqualifying other kinds of information, the work focussed on digitally mediated social trails of other users. Building on experience from the prototype work and an investigation into in seamful design, observability and awareness, I have investigated the effects of making a computational system’s social context observable to users in a way that - is separated from the service’s main functionality in the interface, allowing it to become peripheral and non-obtrusive; - uses simple models and little interpretation; - to some extent opens up the service to allow for user appropriation of both service content and functionality; and - is informative rather than proactive in order to empower the user rather than acting on the user’s behalf. By designing systems that fulfil these criteria I claim that the user will be supported in performing the task at hand, with or without the service, and that with service use, the user will become more and more aware of the possibilities and limitations of the underlying technology. In addition, the digitally mediated hybrid spaces where physical, social and digital contexts meet constitute application domains in themselves, domains that users may enjoy exploring.

    Who, what and where in Kista Galleria. An ethnographically inspired study of a shopping mall and mobile life within2003Rapport (Annet vitenskapelig)
    Abstract [en]

    An ethnographically inspired study was performed in the Kista Galleria shopping mall. The objective was to provide input to the design of a mobile social service running on mobile telephones. User behaviour was observed indicating opportunities for a service to manifest itself on a user's mobile phone without being too obtrusive: phone walking, glancing, and logging on and off. The study also provided insight as to places in the mall where people tend to gather and stop for some time span: waiting rooms. Such places are appropriate for the placement of server stations and public server displays.

    Paper Prototyping a Social Mobile Service2003Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Methods for design and evaluation of interactive applications are not readily applicable to mobile services. By modifying an existing paper prototyping method we evaluated a mobile social service for providing user-based tips in a shopping mall. The evaluation showed that tips can be pushed to users and that they can accept that a complex user interface is presented on a small screen. Although the evaluation took place in an office environment, we received feedback on functionality of the service in the context of the shopping mall. Our evaluation indicates that simple prototyping techniques can be used for informative evaluations of mobile services that are heavily context dependent.

    Abstract [en]

    A problem when making recommendations based on the aggregated behavior of many users (collaborative recommendation) is to explain the rationale behind the recommendation. Our work investigates the alternative approach of visualizing the collaborative data, leaving it to the user to decide on a course of action, i.e. create the recommendation. A prototype system was built and evaluated in a joint project with the international transport and travel service company Stena Line. A user study showed that displaying statistics on other traveler’s ticket bookings indeed functioned as recommendations.

    Designing a Mobile Social Service for a Mall: User Experiences of Kista Galleria2003Rapport (Annet vitenskapelig)
    Abstract [en]

    A study was performed to investigate a domain for a mobile and social service, where a web of social trails is overlaid over a physical space. Using a method inspired by work of the city planner Kevin Lynch, 20 subjects were interviewed about their experiences, activities, movements and habits related to a specific shopping mall. Design implications for the service were drawn from subjects’ sketches of the area, lists of places important to them, and their daily routes through the mall as drawn on a standardized map. Three user groups were identified based on the amount of activities and time spent in the mall: dwellers, shoppers and exploiters. User sketches indicated that traditional maps are not an optimal means for visualising the mall in the service. Finally, the way subjects grouped, labelled and defined places and objects in the mall provided valuable input to the design of the service interface.

    Mobile settings are not only physically and digitally mediated; they are also inhabited by people - a social space. We argue that careful design exposing the connections, gaps, overlays and mismatches within and between physical, digital and social space allow for a better understanding and thereby mastering of the resulting combined space. Two concepts are explored in MobiTip, a social mobile service for exchanging opinions among peers: intramedia seams concerning network coverage and position technology, and intermedia seams between digitally transmitted tips and the physical, social context surrounding the user. We introduce social positioning as an alternative and complement to the current strive for seamless connectedness and exact positioning in physical space.

    Capturing TV user behaviour in fictional character descriptions2008Rapport (Annet vitenskapelig)
    Abstract [en]

    This work is part of the On-demand IPTV project, conducted by Acreo and SICS with financing from Vinnova and active support from an industrial consortium. The main goal of the project is to study the demands on cost-effective, scalable video-on-demand networks that can deliver video with high-quality with minor quality degradations in the transmission. An important issue in understanding this situation is to explore future user behaviour (and the resulting traffic patterns) when user can choose a mix of broadcast TV and a large number of on-demand channels and services. This paper reports on the first steps to develop an understanding of IPTV user behaviour by investigating the current situation using archetypical, fictional character descriptions often referred to as personas. This is an intermediate version; the final version will be the result of Task 4.1: User requirements analysis, part of WP 4: User needs and behaviour.

    How to choose and how to watch: an on-demand perspective on current TV practices2010Rapport (Annet vitenskapelig)
    Abstract [en]

    In Sweden, digital TV services have until very recently not been accessible to most people through the TV set. At the same time, TV channels offer more and more content on the web and the majority of the population has access to high-speed internet connections. A web survey aimed at investigating attitudes and behavior related to on-demand TV was distributed in December 2008 to 52 households in an experimental, open (operator neutral) access network in Sweden. Questions were posed on TV arrangements, habits and attitudes; social aspects of TV watching; watching film or TV on-demand; and watching film or TV using the computer. Complementary interviews were also performed with participants that were not part of the experimental environment. Results show that participants in the studies understood and felt a need for time-shift and on-demand TV services: time-shift needs for re-scheduling, catch-up and repeats were expressed as well as on-demand needs for movies and for accessing otherwise unavailable TV content. Support for on-demand TV could also be found in that subjects reported little need for viewing TV content according to a broadcast schedule, with the main exception of news, sports events and other live broadcasts.

    Interactive adaptation of Intranet newsletters1997Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose a new approach to edit and adapt information from the web. The advantage of the proposed approach, edited adaptive hypermedia, is that it combines human expertise with machine intelligence. A user-adaptive WWW browser communicates with an information broker environment, in which information can be retrieved and structured to fit the target user group or groups. We exemplify the approach with an application at a Swedish company: newsletter distribution on an Intranet. The information is adapted at the reader side, based on annotations on each article from the newsletters.

    Information services based on user profile communication1999Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Web-based, user-adaptive information services impose a difficult requirement on user modeling: the inference schema for user modeling and user-adapted information retrieval must be maintained over time. There are two reasons for this: 1) the information itself may change; and 2) the user group is largely unknown from the start, and may change during the usage of the system. To address these problems, we view profile structures and information classifications as means of communication as well as means for automatic information retrieval. Users communicate their information needs, and editors communicate the structure and content of available information. Our focus is to provide tools in which such communication can be efficiently accomplished. These tools are then used to enhance the day-to-day information retrieval in terms of information filtering and search. In this paper, we propose a design for web information services based on user profile communication. We illustrate the approach by an example application, in which conference and workshop calls are collected and distributed to interested users. We present the results of an initial study of this system, which points towards the most important characteristics of this collaboration. Finally, we discuss future extensions for the system.

    Can readers understand their profiles: a study of user profiling for information filtering2001Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The aim in information filtering is to provide users with a personalised selection of information, based on a description of their interest profile. These can be automatically generated or set by users. We can expect that users sometimes will want to be able to review their profiles even if they are system generated. We present a study of the effects of combining automatic profiling with explicit user involvement. Firstly, we wanted to explore if a machine-learned profile would benefit from being based on an initial explicit user profile. Secondly, we tested if profiles that provided better filtering also were better liked by users. Finally, we tested if users could make improvements to machine-learned profiles. We found that the initial set-up of a personal profile was effective, and yielded performance improvements even after feedback training. However, the study showed no correlation between users ratings of profiles and their filtering performance. Neither were there any conclusive evidence that users could improve on the system-generated profiles.

    ConCall: An information service for researchers based on EdInfo1998Rapport (Annet vitenskapelig)
    Abstract [en]

    In this paper, we present new types of web information services, where users and information brokers collaborate in creating a user-adaptive information service. Such services impose a novel task on information brokers: they become responsible for maintaining the inference strategies used in user modeling. In return, information brokers obtain more accurate information about user needs, since the adaptivity ensures that user profiles are kept up to date and consistent with what users actually prefer, not only what they say that they prefer. We illustrate the approach by an example application, in which conference calls are collected and distributed to interested readers.

    ConCall: Edited and Adaptive Information Filtering1999Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The information overflow problem is not simply one of information retrieval and information filtering: the user (reader) might also require aid in summarizing the retrieved information and judging its accuracy and quality. This shows that there is a clear role for the information broker, the human expert that gathers, structures, and evaluates information. Typically information-brokering services of today utilize a predefined classification schema for information. Readers can individualize the service by selecting from the predefined categories. This approach has many disadvantages. First, the individual readers must select between classes of information that may be orthogonal to their real interests. Second, they are forced to use the broker's classification not only for retrieval, but also for structuring the retrieved information. Third, it becomes impossible for readers to indicate that they are looking for types of information that are not covered by the service. Finally, as the information changes over time, the classification schema may have to change. In the EdInfo project [1] we have chosen a different approach. Editors, information brokers, readers, and information services may all use different classification schemas, and change them over time. Techniques from collaborative and intelligent filtering as well as information retrieval are used to create tools that allow services, brokers, and readers to communicate and synchronize their classification schemas.

    Digital Libraries: Information Broker Roles in Collaborative Filtering1998Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The main goal of the EdInfo project [1] is to utilize human information brokers, or editors, as a resource in adaptive information systems. An information broker can be any of the following: The dedicated expert that collects and potentially reviews literature within a restricted area of interest; The journalist that produces articles with specific reader groups in mind; The librarian that organizes incoming information and directs readers to various sources; The professional information broker, that processes specific information requests, seeks for appropriate information sources, and produces summaries of the obtained information. The common characteristic of these roles is that the information broker has some kind of understanding of what his or her customers want, and is willing to adapt to these needs. Information brokers collect information from various sources, evaluate its relative importance and then choose whether to include the information as it is, disregard it, summarize it, or perhaps rewrite or illustrate it differently than in the original source.
