  1. 1. Sentiment and Stance Visualization of Textual Data for Social Media

    Författare :Kostiantyn Kucher; Andreas Kerren; Carita Paradis; Magnus Sahlgren; Ross Maciejewski; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stance visualization; sentiment visualization; text visualization; stance analysis; sentiment analysis; opinion mining; visualization; interaction; visual analytics; NLP; text mining; text analytics; social media; Informations- och programvisualisering; Information and software visualization;

    Sammanfattning : Rapid progress in digital technologies has transformed the world in many ways during the past few decades, in particular, with the new means of communication such as social media. Social media platforms typically rely on textual data produced or shared by the users in multiple timestamped posts. LÄS MER

  3. 2. Algorithmically Guided Information Visualization : Explorative Approaches for High Dimensional, Mixed and Categorical Data

    Författare :Sara Johansson Fernstad; Mikael Jern; Jimmy Johansson; Jane Shaw; Matthew O. Ward; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information visualization; data mining; high dimensional data; categorical data; mixed data;

    Sammanfattning : Facilitated by the technological advances of the last decades, increasing amounts of complex data are being collected within fields such as biology, chemistry and social sciences. The major challenge today is not to gather data, but to extract useful information and gain insights from it. LÄS MER

  4. 3. Visualization of Causal Relations

    Författare :Niklas Elmqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information visualization; causality visualization; citation network visualization; causal relations;

    Sammanfattning : The notion of cause and effect is pervasive in human thinking and plays a significant role in our perception of time. Software systems, in particular parallel and distributed ones, are permeated by this causality, and the human mind is especially well-suited to detect instances of this concept. LÄS MER

  5. 4. Video based analysis and visualization of human action

    Författare :Martin Eriksson; Stefan Carlsson; Ian Reid; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; Motion analysis; Visualization; Human tracking; virtual coach; Människa-dator-interaktion; Information technology; Informationsteknologi;

    Sammanfattning : Analyzing human motion is important in a number of ways. An athlete constantly needs to evaluate minute details about his or her motion pattern. In physical rehabilitation, the doctor needs to evaluate how well a patient is rehabilitating from injuries. Some systems are being developed in order to identify people only based on their gait.

  7. 5. Collaborative Visualization : Designing and evaluating systems for co-located work

    Författare :Lars Winkler Pettersson; Stefan Seipel; Anders Jansson; Oliver Bimber; Uppsala universitet; []
    Nyckelord :Visualization; Human-Computer Interaction; Collaboration; Co-located Visualization; Computer Supported Cooperative Work;

    Sammanfattning : This thesis investigates new ways of using information visualization to support collaboration in co-located work. To study this phenomenon, Multiple Viewer Display Environments (MVDEs) with independent views have been applied to present information such that all viewers at the same time and in the same display can see correct views of 3D models, see correctly oriented text and see different parts and aspects of information in each view.
