    Towards Creating a Knowledge Base for World-Wide Web Documents1997Ingår i: Proceedings of the IASTED International Conference on Intelligent Information Systems, IEEE, 1997, 1, s. 507-511Konferensbidrag (Refereegranskat)
    Abstract [en]

    The lack of organization of the information on the web results in non-efficient information retrieval. Several approaches for improvement have been suggested. We propose to use a document knowledge base that contains semantic and structural information concerning the retrievable documents that is extracted from the actual documents. We show that using such a knowledge base gives a number of advantages among which advanced query functionality. We also discuss the creation of such a knowledge base and in particular we show how we can automatically extract structural information from HTML documents for addition to the document base.

    Secure and scalable E-service software delivery2001Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Due to the complexity of software and end-user operating environments, software management in general is not an easy task for end-users. In the context of e-service, what end-users buy is the service package. Generally speaking, they should not have to be concerned with how to get the required software and how to make it work properly on their own sites. On the other hand, service providers would not like to have their service-related software managed in a non-professional way, which might cause problems when providing services.

    E-service software delivery is the starting point in e-service software management. It is the functional foundation for performing further software management tasks, e.g., installation, configuration, activation, and so on. This thesis concentrates on how to deliver e-service software to a large number of geographically distributed end-users. Special emphasis is placed on the issues of efficiency (in terms of total transmission time and consumed resources), scalability (in terms of the number of end-users), and security (in terms of confidentiality and integrity). In the thesis, we propose an agent-based architectural model for e-service software delivery, aiming at automating involved tasks, such as registration, key management, and recipient status report collection. Based on the model, we develop a multicast software delivery system, which provides a secure and scalable solution to distributing software over publicly accessible networks. By supplying end-users with site information examination, the system builds a bridge towards further software management tasks. We also present a novel strategy for scalable multicast session key management in the context of software delivery, which can efficiently handle a dynamic reduction in group membership of up to 50% of the total. An evaluation is provided from the perspective of resource consumption due to security management activities.

    Ethical Guidelines for Research on Electronic Assistive Technology2006Ingår i: Etik i forskningens vardag / [ed] Anna-Liisa Närvänen & Elisabet Näsman, Linköping: Linköping University , 2006, s. 67-104Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    This paper casts an ethical spotlight on the development of advanced computer systems, in particular assistive technology (e.g. for older people). Recent progress in the design and application of monitoring and automation as well as computer-based cognitive and physical assistance is dramatic - sometimes in a good, sometimes in a bad sense. By analyzing four cases of 21st century assistive technology, the text identifies ethical dilemmas in research and the application of products. A set of design recommendations is derived, intended to inspire development of electronic assistive technology that helps in an effective way without being intrusive.

    Towards Dependable Virtual Companions for Later Life2005Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    When we grow older, we become more vulnerable to certain reductions in quality of life. Caregivers can help, however human care is limited, and will become even scarcer in the near future. This thesis addresses the problem by contributing to the development of electronic assistive technology, which has the potential of effectively complementing human support. In particular, we follow the vision of a virtual companion for later life- an interactive computerbased entity capable of assisting its elderly user in multiple situations in everyday life.

    Older adults will only benefit from such technology if they can depend on it and it does not intrude into their lives against their will. Assuming a software engineering view on electronic assistive technology, this thesis thus formulates both dependability requirements and ethical guidelines for designing virtual companions and related technology (such as smart homes).

    By means of an iterative development process (the thesis covers the first iteration), a component-based design framework for defining dependable virtual companions is formed. Personalised applications can be generated efficiently by instantiating our generic architecture with a number of special-purpose interactive software agents. Scenario-based evaluation of a prototype confirmed the basic concepts of the framework, and led to refinements.

    The final part of the thesis concerns the actual framework components and the applications that can be generated from them. From a field study with elders and experts, we construct a functional design space of electronic assistive technology applications. It relates important needs of different older people to appropriate patterns of assistance. As an example application, the feasibility of driving support by vehicular communication is studied in depth.

    Future iterations with real-world experiments will refine our design framework further. If it is found to scale to the dynamic diversity of older adults, then work can begin on the ultimate project goal: a toolkit on the basis of the framework that will allow semi-automatic generation of personalised virtual companions with the involvement of users, caregivers, and experts.

    Abstract [en]

    Frail older people can normally not be given round-the-clock care-giving assistance. During the time there is no other person around they must be independent. Electronic assistive technology (EAT) can increase an older person's independence in everyday life, but to do so it must be dependable. This paper examines issues of dependability for a special class of EAT software, virtual companions for later life. A virtual companion is a personal system of interconnected functions aiming to assist an elderly user by imitating elder-caregiver interaction. In order to provide designers with an aid for defining, designing, and validating virtual companions, the first part of the paper identifies and discusses the special dependability requirements to be put on such software. The second part describes our own approach, and gives suggestions on how to design for dependability.

    Abstract [en]

    Resources in care for frail older people are limited. Electronic assistive technology can help maintain and improve older people's quality of life, however high requirements need to be put on such systems. As part of an iterative design process, this paper evaluates a framework for the design of interactive, multifunctional, and personalised assistive technology - virtual companions - in relation to previously defined dependability requirements. By means of scenario-based testing of a prototype implementation, we refine the first version of the design framework. The paper concludes with a reflection on our method, and outlines the iteration steps to follow.

    Abstract [en]

    More and more people are living to old age, and it is usually a desire among elderly people to sustain mobility. Unfortunately, the crash rate of older adults is much higher than for other drivers. Older drivers are also more likely to sustain serious injuries that lead to disability or death. Therefore, technological contributions for improving traffic safetyand preserving mobility of older people are important. One promising new approach is to use traffic safety systems based on vehicular communication, where vehicles exchange warning messages. This paper evaluates the feasibility of using such vehicular communication for supporting older drivers in road intersections, which is the most common accident setting for older drivers. Using a temporal reasoning system (ECAM) this accident setting is analysed in depth, and the potential foraccident avoidance is quantified, while taking into account several relevant factors such as speed, driver reaction time, and transmission delay for warning messages. The results indicate the high potential of vehicular communication, and highlight requirements on transmission delay.

    On the Complexity of Discrete Feature Selection for Optimal Classification2010Ingår i: IEEE Transaction on Pattern Analysis and Machine Intelligence, ISSN 0162-8828, E-ISSN 1939-3539, Vol. 32, nr 8, s. 1517-U1522Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Consider a classification problem involving only discrete features that are represented as random variables with some prescribed discrete sample space. In this paper, we study the complexity of two feature selection problems. The first problem consists in finding a feature subset of a given size k that has minimal Bayes risk. We show that for any increasing ordering of the Bayes risks of the feature subsets (consistent with an obvious monotonicity constraint), there exists a probability distribution that exhibits that ordering. This implies that solving the first problem requires an exhaustive search over the feature subsets of size k. The second problem consists of finding the minimal feature subset that has minimal Bayes risk. In the light of the complexity of the first problem, one may think that solving the second problem requires an exhaustive search over all of the feature subsets. We show that, under mild assumptions, this is not true. We also study the practical implications of our solutions to the second problem.

    Home informatics in healthcare: Assessment guidelines to keep up quality of care and avoid adverse effects2003Ingår i: Technology and Health Care - European Society for Engineering and Medicine, ISSN 0928-7329, Vol. 11, nr 3, s. 195-206Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Due to an ageing population and improved treatment possibilities, a shortage in hospital beds is a fact in many countries. Home healthcare schemes using information technology (IT) are under development as a response to this and with the intention to produce a more cost-effective care. So far it has been shown that home healthcare is beneficial to certain patient groups. The trend is a widening of the criteria for admission to home healthcare, which means treatment in the home of more severe conditions that otherwise would require in-hospital care. Home informatics has the potential to become a means of providing good care at home. In this process, it is important to consider what new risks will be encountered when placing electronic equipment in the home care environment. Continuous assessment and guidance is important in order to achieve a safe and effective care. Based on a review of current knowledge this paper presents an inventory of risks and adverse events specific to this area. It was found that risks and adverse events could stem from technology in itself, from human-technology interaction conditions or from the environment in which the technology is placed. As a result from the risk inventory, this paper proposes guidelines for the planning and assessment of IT-based hospital-at-home schemes . These assessment guidelines are specifically aimed at performance improvement and thus to be considered a complement to the more general guidelines on telehomecare adopted by the American Telemedicine Association (ATA) in October 2002.

    Using Vehicular Communication to Support Older Drivers at Road Intersections: A Feasibility Study2004Ingår i: Proceedings of the 2nd International Conference on Smart homes and health Telematics, Amsterdam, The Netherlands: IOS Press , 2004, s. 33-40Konferensbidrag (Refereegranskat)
    Abstract [en]

    More and more people are living to old age, and it is usually a desire among elderly people to sustain mobility. Unfortunately, the crash rate of older adults is much higher than for other drivers. Older drivers are also more likely to sustain serious injuries that lead to disability or death. Therefore, technological contributions for improving traffic safetyand preserving mobility of older people are important. One promising new approach is to use traffic safety systems based on vehicular communication, where vehicles exchange warning messages. This paper evaluates the feasibility of using such vehicular communication for supporting older drivers in road intersections, which is the most common accident setting for older drivers. Using a temporal reasoning system (ECAM) this accident setting is analysed in depth, and the potential foraccident avoidance is quantified, while taking into account several relevant factors such as speed, driver reaction time, and transmission delay for warning messages. The results indicate the high potential of vehicular communication, and highlight requirements on transmission delay.

    Towards Creating Workflows On-the-Fly and Maintaining Them Using the Semantic Web: The sButler Project at Linköping University2003Ingår i: The Twelfth International World Wide Web Conference, 20-24 May 2003, Budapest, Hungary, New York: ACM , 2003Konferensbidrag (Refereegranskat)
    Abstract [en]

    In the sButler project (Semantic Web Butler) at Linköpingsuniversitet, Sweden, we examine the modeling and instantiation ofworkflows based on Web services (services described in a rule-basedlanguage). The aim of the project, which is part of the SwedishSemantic Web initiative, is to support on-the fly creation ofworkflows and their subsequent maintenance. Our sButler agent willmanage workflows and Web services modeled as Petri Nets, use thelanguage facilities provided by the Semantic Web, and employ a newpush-and-pull protocol to handle communication with other sButlers.

    A classification for comparing standardized XML data2006Ingår i: Database and Expert Systems Applications, 2006. DEXA '06, Los Alamitos, CA, USA: IEEE Computer Society, 2006, s. 517-524Konferensbidrag (Refereegranskat)
    Abstract [en]

    The increasing amount of XML data provided via the Web imposes a large need for efficient data exchange and import. This has led to an increasing interest in XML standards within a large number of areas. However, in most application domains there are several competing standards capturing the same kind of information. This work presents a method for classification and comparison of standards within an area. The method can be applied to XML-standards in any domain. We report on the situation for two different areas, molecular interactions and digital television and use our method to compare the standards within the two domains. The classification gives information on how similar the standards are, in terms of information content and structure. This information is useful for deciding which kind of methods are interesting for providing automatic matching and efficient development of tools for import of standardised data

    Possibilities and Challenges Using XML Technology for Storage and Integration of Molecular Interactions2005Ingår i: International Workshop on Database and Expert Systems Applications DEXA05,2005, Los Alamitos, CA, USA: IEEE Computer Society , 2005, s. 575-Konferensbidrag (Refereegranskat)
    Abstract [en]

    The amount of data emerging from experiments on molecular and protein interactions is rapidly growing. It is of high importance to understand these datasets, putting them together to meaningful pathways describing some aspects of the cell physiology. Currently, there is a big interest in XML representations of protein interaction and molecular pathways. New standards, SBML, PSI MI and BioPAX are under development and it is of high importance to build tools for easy integration and analysis of data represented in these standards. There are currently two main approaches for storage of data represented within XML, one is to base the tools directly on XML while the other is to translate the information into a relational database. In this paper we report on experiments with these approaches for storage and analysis of molecular interaction data represented in the standards. The results give important pointers to the possibility of building easy to use tools.

    XML representations of pathway data: a comparison2004Ingår i: The ACM SIGIR04 Workshop on Search and Discovery in Bioinformatics,2004, 2004Konferensbidrag (Refereegranskat)
    Abstract [en]

    Standardisation and integration of pathway data is currently an interesting topic within bioinformatics with several consortia,e.g.SBML, PSI MI and BioPAX.These groups use or consider XML for representation of their standards. Furthermore, XML is used by many of the existing databases containing pathway information for export and exchange of data. In this paper we compare some of the XML representations used by the standardisation committees and existing databases. The contribution of the paper is the comparison and evaluation of the representations together with a discussion on implications for information discovery and integration.

    An Extension of XQuery for Graph Analysis of Biological Pathways2009Ingår i: Proc. The First International Conference on Advances in Databases, Knowledge, and Data Applications, DBKDA 2009,, 2009, s. 22-27Konferensbidrag (Refereegranskat)
    Abstract [en]

     The vast quantity of scientific data produced in life sciences demands the use of sophisticated storage and analysis techniques. In particular, for biological pathways graph analysis plays an important role and data is commonly available in XML-based formats. Thus, there is a growing need to make analysis capabilities available through query languages for XML. This paper presents an approach to extend XQuery for graph analysis with focus on data for biological pathways. A graph model is introduced within the XQuery environment. New built-in functions define the available operations on the graph model. XQuery expressions can be utilized to populate graphs with data and execute graph algorithms. Graph data and results of algorithms can be accessed in an XML representation for further processing. In addition, a reference mechanism can be used to preserve associations from graph data to the original XML data. The approach has been implemented as an extension to exist. First evaluations of the implementation show that the introduced approach is practical and efficient for reaction networks with several thousand vertices and edges.

    From information management to task management in electronic mail2002Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Electronic mail (e-mail) is an under-utilised resource of information and knowledge. It could be an important part of the larger so-called organisational memory (OM)—if it were not so disorganised and fragmented. The OM contains the knowledge of the organisation’s employees, written records, and data. This thesis is about organising and managing information in, and about, e-mail so as to make it retrievable and usable for task management purposes.

    The approach is user-centred and based on a conceptual model for task management. The model is designed to handle tasks that occur in the communications in an open distributed system, such as Internet e-mail. Both structured and unstructured tasks can be supported. Furthermore, the model includes management of desktop source information, which comprises the different electronically available sources in a user’s computer environment. The information from these is used in the model to sort information and thereby handle tasks and related information. Tasks are managed as conversations, that is, exchanges of messages.

    We present a language called Formal Language for Conversations (FLC), based on speech act theory, which is used to organise messages and relevant information for tasks. FLC provides the container for task-related information, as well as the context for managing tasks. The use of FLC is exemplified in two scenarios: scheduling a meeting and making conference arrangements. We describe a prototype based on the conceptual model. The prototype explicitly refines and supports the notion of threads, which are employed so as to give tasks a context. It integrates the use of FLC into the traditional threading mechanism of e-mail, in addition to matching on text in the body. An agent architecture is also described, which is used to harmonise the information in the heterogeneous desktop sources. Finally, human-readable filtering rules created by a machine learning algorithm are employed in the prototype. The prototype is evaluated with regard to its thread-matching capability, as well as the creation of usable and readable filtering rules. Both are deemed satisfactory.

    Aligning and Merging Biomedical Ontologies2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Due to the explosion of the amount of biomedical data, knowledge and tools that are often publicly available over the Web, a number of difficulties are experienced by biomedical researchers. For instance, it is difficult to find, retrieve and integrate information that is relevant to their research tasks. Ontologies and the vision of a Semantic Web for life sciences alleviate these difficulties. In recent years many biomedical ontologies have been developed and many of these ontologies contain overlapping information. To be able to use multiple ontologies they have to be aligned or merged. A number of systems have been developed for aligning and merging ontologies and various alignment strategies are used in these systems. However, there are no general methods to support building such tools, and there exist very few evaluations of these strategies. In this thesis we give an overview of the existing systems. We propose a general framework for aligning and merging ontologies. Most existing systems can be seen as instantiations of this framework. Further, we develop SAMBO (System for Aligning and Merging Biomedical Ontologies) according to this framework. We implement different alignment strategies and their combinations, and evaluate them in terms of quality and processing time within SAMBO. We also compare SAMBO with two other systems. The work in this thesis is a first step towards a general framework that can be used for comparative evaluations of alignment strategies and their combinations.

    Due to the recent explosion of the amount of on-line accessible biomedical data and tools, finding and retrieving the relevant information is not an easy task. The vision of a Semantic Web for life sciences alleviates these difficulties. A key technology for the Semantic Web is ontologies. In recent years many biomedical ontologies have been developed and many of these ontologies contain overlapping information. To be able to use multiple ontologies they have to be aligned or merged. In this paper we propose a framework for aligning and merging ontologies. Further, we developed a system for aligning and merging biomedical ontologies (SAMBO) based on this framework. The framework is also a first step towards a general framework that can be used for comparative evaluations of alignment strategies and their combinations. In this paper we evaluated different strategies and their combinations in terms of quality and processing time and compared SAMBO with two other systems.

    The amount of biomedical information that is disseminated over the Web increases every day. This rich resource is used to find solutions to challenges across the life sciences. The Semantic Web for life sciences shows promise for effectively and efficiently locating, integrating, querying and inferring related information that is needed in daily biomedical research. One of the key technologies in the Semantic Web is ontologies, which furnish the semantics of the Semantic Web. A large number of biomedical ontologies have been developed. Many of these ontologies contain overlapping information, but it is unlikely that eventually there will be one single set of standard ontologies to which everyone will conform. Therefore, applications often need to deal with multiple overlapping ontologies, but the heterogeneity of ontologies hampers interoperability between different ontologies. Aligning ontologies, i.e. identifying relationships between different ontologies, aims to overcome this problem. A number of ontology alignment systems have been developed. In these systems various techniques and ideas have been proposed to facilitate identification of alignments between ontologies. However, there still is a range of issues to be addressed when we have alignment problems at hand. The work in this thesis contributes to three different aspects of identification of high quality alignments: 1) Ontology alignment strategies and systems. We surveyed the existing ontology alignment systems, and proposed a general ontology alignment framework. Most existing systems can be seen as instantiations of the framework. Also, we developed a system for aligning biomedical ontologies (SAMBO) according to this framework. We implemented various alignment strategies in the system. 2) Evaluation of ontology alignment strategies. We developed and implemented the KitAMO framework for comparative evaluation of different alignment strategies, and we evaluated different alignment strategies using the implementation. 3) Recommending optimal alignment strategies for different applications. We proposed a method for making recommendations.

    Abstract [en]

    Due to the recent explosion of the amount of on-line accessible biomedical data and tools, finding and retrieving the relevant information is not an easy task. The vision of a Semantic Web for life sciences alleviates these difficulties. A key technology for the Semantic Web is ontologies. In recent years many biomedical ontologies have been developed and many of these ontologies contain overlapping information. To be able to use multiple ontologies they have to be aligned or merged. In this paper we propose a framework for aligning and merging ontologies. Further, we developed a system for aligning and merging biomedical ontologies (SAMBO) based on this framework. The framework is also a first step towards a general framework that can be used for comparative evaluations of alignment strategies and their combinations. In this paper we evaluated different strategies and their combinations in terms of quality and processing time and compared SAMBO with two other systems.

    Abstract [en]

    Ontologies are an important technology for the Semantic Web and many ontologies have already been developed. Many ontologies also contain overlapping information and to be able to use them together effectively, we need to align them. Some of the current alignment techniques use information about the structure of the ontologies, but they have not produced good results in evaluations. We propose an approach where, in contrast to the other approaches, structural information is used as a filtering method in the alignment process. We evaluate the approach in terms of quality and performance.

    Abstract [en]

    Ontologies are an important technology for the Semantic Web. In different areas ontologies have already been developed and many of these ontologies contain overlapping information. Often we would therefore want to be able to use multiple ontologies. To obtain good results, we need to find the relationships between terms in the different ontologies, i.e. we need to align them. Currently, there exist a number of systems that support users in aligning ontologies, but not many comparative evaluations have been performed and there exists little support to perform such evaluations. However, the study of the properties, the evaluation and comparison of the alignment strategies and their combinations, would give us valuable insight in how the strategies could be used in the best way. In this paper we propose the KitAMO framework for comparative evaluation of ontology alignment strategies and their combinations and present our current implementation. We evaluate the implementation with respect to performance. We also illustrate how the system can be used to evaluate and compare alignment strategies and their combinations in terms of performance and quality of the proposed alignments. Further, we show how the results can be analyzed to obtain deeper insights into the properties of the strategies.

    Abstract [en]

    In different areas ontologies have been developed and many of these ontologies contain overlapping information. Often we would therefore want to be able to use multiple ontologies. To obtain good results, we need to find the relationships between terms in the different ontologies, i.e. we need to align them. Currently, there already exist a number of different alignment strategies. However, it is usually difficult for a user that needs to align two ontologies to decide which of the different available strategies are the most suitable. In this paper we propose a method that provides recommendations on alignment strategies for a given alignment problem. The method is based on the evaluation of the different available alignment strategies on several small selected pieces from the ontologies, and uses the evaluation results to provide recommendations. In the paper we give the basic steps of the method, and then illustrate and discuss the method in the setting of an alignment problem with two well-known biomedical ontologies. We also experiment with different implementations of the steps in the method.

    Intelligent software delivery using P2P2002Ingår i: 2nd IEEE International Conference on Peer-to-Peer Computing, 2002, s. 136-143Konferensbidrag (Refereegranskat)
    Abstract [en]

    Internet has given software providers possibilities for electronic software distribution (ESD). At the same time bandwidth limitations lead to poor performance and scalability of the delivery process. The problem is even harder when delivering large, resource consuming software packages and media content. We propose an agent-based architectural model as amiddleware for intelligent P2P electronic software delivery. In this paper we analyze the possibility of applying the peer-to-peer technology to the process of software delivery, relying on the experience and learned lessons of the related technologies. To this effect we analyze the available material on this topic and identify the important criteria that are crucial for the wide acceptance of ESD by both software providers and end-users. We argue that the proposed model can be used in building a system that meets most, if not all, of the identified criteria. The work presented in this paper opens a number of interesting research issues and investigation opportunities.

    Information Sharing and User Privacy in the Third-party Identity Management Landscape2015Ingår i: Proc. ACM Conference on Data and Application Security and Privacy (ACM CODASPY), ACM Digital Library, 2015, s. 151-153Konferensbidrag (Refereegranskat)
    Abstract [en]

    Third-party identity management services enable cross-site information sharing, making Web access seamless but also raise significant privacy implications for the users. Using a combination of manual analysis of identified third-party identity management relationships and targeted case studies we capture how the protocol usage and third-party selection is changing, profile what information is requested to be shared (and actions to be performed) between websites, and identify privacy issues and practical problems that occur when using multiple accounts (associated with these services). The study highlights differences in the privacy leakage risks associated with different classes of websites, and shows that the use of multiple third-party websites, in many cases, can cause the user to lose (at least) partial control over which information is shared/posted on their behalf.

    Integration of organizational workflows and the semantic web2005Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The Internet and the Web provide an environment to do business-to-business in a virtual world where distance is less of an issue. Providers can advertise their products globally and consumers from all over the world obtain access to these products. However, the heterogeneous and continually changing environment leads to several problems related to finding suitable providers that can satisfy a consumer's needs. The Semantic Web aims to alleviate these problems.

    By allowing software agents to communicate and understand the information published on the Web, the Semantic Web enables new ways of doing business and consuming services. Semantic Web technology will provide an environment where the comparison of different business contracts will be made in a matter of minutes, new contractors may be discovered continually and the organizations' routines may be automatically updated to reflect new forms of cooperation.

    Organizations, however, do not necessarily use the Semantic Web infrastructure to communicate internally. Consequently, to be able to gain new advantages from using Semantic Web technology, this new technology should be integrated into existing routines.

    In this thesis, we propose a model for integrating the usage of the Semantic Web into an organization's work routines. We provide a general view of the model as well as an agent-based view. The central component of the model is an sButler, a software agent that mediates between the organization and the Semantic Web. We describe an architecture for one of the important parts of the sButler, the process instance generation, and focus on its service retrieval capability. Further, we show the feasibility of our approach with a prototype implementation, and discuss an experiment.

    Abstract [en]

    Information extraction helps in building advanced tools for text processing applications such as electronic publishing and information retrieval. The applications differ in their requirements on the input text, output information, and available resources for information extraction. Since existing IE technologies are application specific, extensive expert work is required to meet the needs of each new application. However, today, most users do not have this expertise and thus need a tool to easily create IE systems tailored to their needs. We introduce a framework that consists of (1) an extensible set of advanced IE technologies together with a description of the properties of their input, output, and resources, and (2) a generator that selects the relevant technologies for a specific application and integrates these into an IE system. A prototype of the framework is presented, and the generation of IE systems for two example applications is illustrated. The results are presented as guidelines for further development of the framework.

    An Evaluation Platform for Semantic Web Technology2006Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The vision of the Semantic Web aims at enhancing today's Web in order to provide a more efficient and reliable environment for both providers and consumers of Web resources (i.e. information and services). To deploy the Semantic Web, various technologies have been developed, such as machine understandable description languages, language parsers, goal matchers, and resource composition algorithms. Since the Semantic Web is just emerging, each technology tends to make assumptions about different aspects of the Semantic Web's architecture and use, such as the kind of applications that will be deployed, the resource descriptions, the consumers' and providers' requirements, and the existence and capabilities of other technologies. In order to ensure the deployment of a robust and useful Semantic Web and the applications that will rely on it, several aspects of the technologies must be investigated, such as whether the assumptions made are reasonable, whether the existing technologies allow construction of a usable Semantic Web, and the systematic identification of which technology to use when designing new applications.

    In this thesis we provide a means of investigating these aspects for service discovery, which is a critical task in the context of the Semantic Web. We propose a simulation and evaluation platform for evaluating current and future Semantic Web technology with different resource sets and consumer and provider requirements. For this purpose we provide a model to represent the Semantic Web, a model of the evaluation platform, an implementation of the evaluation platform as a multi-agent system, and an illustrative use of the platform to evaluate some service discovery technology in a travel scenario. The implementation of the platform shows the feasibility of our evaluation approach. We show how the platform provides a controlled setting to support the systematic identification of bottlenecks and other challenges for new Semantic Web applications. Finally, the evaluation shows that the platform can be used to assess technology with respect to both hardware issues such as the kind and number of computers involved in a discovery scenario, and other issues such as the evaluation of the quality of the service discovery result.

    Dealing with Malnutrition: A Meal Planning System for Elderly2006Ingår i: AAAI Spring Symposium on Argumentation for Consumers of Health Care,2006, Menlo Park, CA, USA: AAAI Press , 2006Konferensbidrag (Refereegranskat)
    Abstract [en]

    Malnutrition is a serious problem among people of old age. To overcome malnutrition, a change of food consumption behaviour is necessary, which needs to be based on specialist advice from health-care professionals. Changing food-related behaviour, however, is known to be difficult. Our approach to this problem is to provide an intelligent meal planning system to be used by the elderly person in his or her home. The system provides recommendations of suitable food recipes, taking into account the advice of the care givers (e.g. in terms of dietary restrictions, suitable energy and fat levels, etc). We describe the requirements, design, algorithms, and user interface of the system, and discuss ongoing and future work.
