1. 16. Subject retrieval in web-based library catalogs

   Författare :Koraljka Golub; Jadranka Lasić-Lazić; Department of Information Science Filozofski fakultet u Zagrebu; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; British university libraries; Croatian university libraries; Indexing and retrieval systems; Online library catalogs; Subject access points; Subject retrieval; User interface; User search behavior; WebPACs; Library and Information Science; Biblioteks- och informationsvetenskap;

   Sammanfattning : This thesis has been motivated by past research, problems and realizations that online library catalog users frequently perform subject searches – using keywords, subject headings and descriptors – and these searches have yielded unsatisfactory results. Web-based catalogs or WebPACs (Web-based Online Public Access Catalogs), belonging to the so-called third generation of online catalogs and providing a wide variety of search options, remain largely underutilized despite the continuous advancement of information retrieval systems.

3. 17. Enabling the user - Exploring methodological effects on user requirements elicitation

   Författare :Pontus Wallgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; requirement elicitation; enable; user; product development;

   Sammanfattning : This thesis concerns centred product development and more specifically how methodological choices in user requirements elicitation can enable the users to communicate their requirements to the product developers. During the development process choices have to be made concerning what methodology to use for eliciting user requirements. LÄS MER

   Sammanfattning : The purpose of this licentiate thesis is to contribute to the knowledge about user needs for individual mobility assistive technology (AT) transfer devices. Two qualitative user studies, which were part of a design project, constitute the empirical data. LÄS MER

7. 20. Mutual Understanding in Situated Interactions with Conversational User Interfaces : Theory, Studies, and Computation

   Författare :Dimosthenis Kontogiorgos; Joakim Gustafsson; Gabriel Skantze; Catherine Pelachaud; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; social robots; smart-speakers; multimodal behaviours; social signal processing; common ground; dialogue and discourse; joint-construction tasks; embodiment; conversational failures; Computer Science; Datalogi;

   Sammanfattning : This dissertation presents advances in HCI through a series of studies focusing on task-oriented interactions between humans and between humans and machines. The notion of mutual understanding is central, also known as grounding in psycholinguistics, in particular how people establish understanding in conversations and what interactional phenomena are present in that process.
