  1. 1. Public computer systems, the client-organization encounter, and the societal dialogue

    Författare :Åke Grönlund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Public computer systems; societal information systems; participation; societal dialogue; communication; information systems; Internet;

    Sammanfattning : Public computer systems (PCS) are systems designed for use at the interface between organizations and their clients. PCS intervene in client-organization relations; the questions discussed in this thesis are what role they play in the client-organization encounter, what role they could and should play, and what theories might be available to guide the development of such systems.

  3. 2. Dialogue Behavior Management in Conversational Recommender Systems

    Författare :Pontus Wärnestål; Arne Jönsson; Lars Degerstedt; Robert Dale; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Natural Language Interaction; Dialogue Systems; Recommender Systems; Dialogue Strategy Management; User Modeling; Preference Management; Computational linguistics; Datorlingvistik;

    Sammanfattning : This thesis examines recommendation dialogue, in the context of dialogue strategy design for conversational recommender systems. The purpose of a recommender system is to produce personalized recommendations of potentially useful items from a large space of possible options. LÄS MER

  4. 3. The human-computer interface in commercial systems : Investigations of dialogue design factors and usability with alphanumeric display terminals

    Författare :Bengt Johnsson; Bertil Andersson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; administrative process; administrative system; commercial system; controlled experimentation; criteria; design property; display terminal; field investigation; human-computer interface; man-computer dialogue; man-machine matching; terminal user; usability; Information Systems; Informatik;

    Sammanfattning : When terminal based computer systems are incorporated in administrative processes, man-computer interface technology for many reasons becomes a crucial problem area. Terminal users ("terminalists") in such systems account for a vast number of terminal hours. LÄS MER

  5. 4. Design and Development of Recommender Dialogue Systems

    Författare :Pontus Johansson; Arne Jönsson; Lars Degerstedt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multimodal; PGP; information-providing; dialogue systems; multimodality; Computer science; Datavetenskap;

    Sammanfattning : The work in this thesis addresses design and development of multimodal dialogue recommender systems for the home context-of-use. In the design part, two investigations on multimodal recommendation dialogue interaction in the home context are reported on. LÄS MER

  7. 5. Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human–Computer Interaction

    Författare :Joakim Gustafson; KTH; []
    Nyckelord :Spoken dialogue system; multimodal; speech; GUI; animated agents; embodied conversational characters; talking heads; empirical user studies; speech corpora; system evaluation; system development; Wizard of Oz simulations; system architecture; linguis; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. The dialogue systems have been multimodal, giving information both verbally with animated talking characters and graphically on maps and in text tables. LÄS MER
