  1. 11. Design and use of ontologies in information-providing dialogue systems

    Författare :Annika Flycht-Eriksson (Silvervarg); Arne Jönsson; Lars Degerstedt; Magnus Merkel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer programs; artificiell intelligens; ontology; information-providing dialogue systems; dialogue management; semantic; Computer science; Datavetenskap;

    Sammanfattning : In this thesis, the design and use of ontologies as domain knowledge sources in information-providing dialogue systems are investigated. The research is divided into two parts, theoretical investigations that have resulted in a requirements specifications on the design of ontologies to be used in information-providing dialogue systems, and empirical work on the development of a framework for use of ontologies in information-providing dialogue systems.

  3. 12. Information state based speech recognition

    Författare :Rebecca Jonson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; dialogue systems; speech recognition; language modelling; dialogue move; dialogue context; ASR; higher level knowledge; linguistic knowledge; N-Best re-ranking; confidence scoring; confidence annotation; information state; ISU approach;

    Sammanfattning : One of the pitfalls in spoken dialogue systems is the brittleness of automatic speech recognition (ASR). ASR systems often misrecognize user input and they are unreliable when it comes to judging their own performance. LÄS MER

  4. 13. Kundupplevd kvalitet i tjänsteverksamheter: En analys och kritik av den företagsekonomiska dialogen

    Författare :Jan E Persson; Institutionen för tjänstevetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic theory; econometrics; Economics; Marknadsanalys; Market study; Reason; Meaning; Dialogue; Interaction; Perception; Expectation; Service Quality; Satisfaction; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : The contemporary discussion about how to define and measure the quality of services is dominated by a subjective perspective and quality is usually grounded in the customers perception. This conceptualisation of quality (perceived service quality) is well established in business and research. LÄS MER

  5. 14. Language Modelling and Error Handling in Spoken Dialogue Systems

    Författare :Genevieve Gorrell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Language Modelling; Spoken Dialogue Systems; Error Handling; Computer science; Datavetenskap;

    Sammanfattning : Language modelling for speech recognition is an area of research currently divided between two main approaches: stochastic and grammar-based approaches are each being differently preferred for their respective strengths and weaknesses. At the same time, dialogue systems researchers are becoming aware of the potential value of handling recognition failures better to improve the user experience. LÄS MER

  7. 15. Shaping sustainable food systems : Local participation in addressing global challenges

    Författare :Aniek Hebinck; Line Gordon; Joost M. Vervoort; Stephan Barthel; Moya Kneafsey; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; food systems; sustainability; food governance; transformative change; participatory processes; participation; civil society; niche level; food policy; urban food; urban agriculture; food poverty; imagined futures; foresight; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : The current unsustainable trajectory of food systems puts the social and ecological processes and functions on which human flourishing depends at risk. This last decade has seen, on one hand, continued insistence on transformative action and on the other, uncertainty and instability with respect to traditional, established institutions, such as the state.
