    Abstract : The last couple of years have marked the entire field of information technology with the introduction of a new global resource, called data. Certainly, one can argue that large amounts of information and highly interconnected and complex datasets were available since the dawn of the computer and even centuries before. READ MORE

  4. 2. Reconsidering the avatar : From user mirror to interaction locus

    Author : Kai-Mikael Jää-Aro; Yngve Sundblad; Wolfgang Prinz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; virtual environments; computer-supported collaborative work; user representation; human-computer interaction;

    Abstract : This thesis is concerned with shared virtual environmentsfor collaborative work. An important aspect of shared virtualenvironments is the avatar, the representation of the user inthe virtual world. READ MORE

  5. 3. Search Processes, User Behaviour and Archival Representational Systems

    Abstract : Information technology and political motives, e.g. e-governance, freedom of information legislation, has recent years lead to an increasing emphasis on users and access to records, but little research based knowledge about those issues exist so far. The main focus of the previous research is the use of non-current records in archival repositories. READ MORE

  6. 4. Fostering User Involvement in Ontology Alignment and Alignment Evaluation

    Author : Valentina Ivanova; Patrick Lambrix; Nahid Shahmehri; Fabien Gandon; Linköpings universitet; []

    Abstract : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. READ MORE
