1. 6. 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. 7. Domain Knowledge Management in Information-providing Dialogue Systems

   Författare :Annika Flycht-Eriksson (Silvervarg); Arne Jönsson; Nils Dahlbäck; Lars Degerstedt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dialogue management; computer systems; Domain knowledge manager; Databehandling Tillämpningsprogram Systemprogram; Artificiell Intelligens AI; Computer science; Datavetenskap;

   Sammanfattning : In this thesis a new concept called domain knowledge management for informationproviding dialogue systems is introduced. Domain knowledge management includes issues related to representation and use of domain knowledge as well as access of background information sources, issues that previously have been incorporated in dialogue management.

4. 8. Pro-environmental travel behavior : The importance of attitudinal factors, habits, and transport policy measures

   Författare :Louise Eriksson; Jörgen Garvill; Annika Nordlund; Linda Steg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; value-belief-norm theory; car habit; policy specific beliefs; car use reduction; acceptability; behavioral adaptations; travel demand management measures; transport policy measures; Psychology; Psykologi;

   Sammanfattning : The aim of this thesis was to study determinants of a readiness for pro-environmental travel behavior in households. Four empirical studies were conducted examining reduction in car use (Study I), acceptability of transport policy measures (Study II and III), and behavioral adaptations in response to travel demand management (TDM) measures (Study IV).

5. 9. Towards an Ontology Development Methodology for Small and Medium-sized Enterprises

   Författare :Annika Öhgren; Kurt Sandkuhl; Henrik Eriksson; Bernhard Holtkamp; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology Development; Ontology Engineering; Small and Medium-sized Enterprises; Survey; Computer science; Datavetenskap;

   Sammanfattning : This thesis contributes to the research field information logistics. Information logistics aims at improving information flow and at reducing information overload by providing the right information, in the right context, at the right time, at the right place through the right channel.

7. 10. Validation of diffusive samplers for nitrogen oxides and applications in various environments

   Författare :Annika Hagenbjörk-Gustafsson; Kåre Eriksson; Greta Smedje; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitrogen dioxide; NOx; diffusive sampling; validation; vehicle exhaust; exposure measurement;

   Sammanfattning : The overall aim of this thesis was to validate diffusive samplers for measurements of nitrogen dioxide (NO2) and nitrogen oxides (NOx). The Willems badge was validated for NO2 measurements both in laboratory tests and in field tests (Paper I-II). The sampling rate was 40.0 mL/min for ambient air concentrations and 46. LÄS MER
