Video. A short 1-MINUTE-OVERVIEW quicktime video without narration gives an illustrative overview about dynamic network visualization.

A longer and narrated INTRO quicktime video shows a user session and a case scenario. Project Manager Dr. Matthias Trier is explaining the concept in a short interview.

A further flash video shows the EVOLUTION of a network. It can be seen how individual authors form bonds which eventually become communities.

Further videos can be seen in the cases (links are found in the navigation window on the left).

Interactive Flash. An interactive CONTACT-MAP(beta) that can be browsed and explored in your webbrowser.

Galleries and Introductions. To provide a better understanding of the look and feel of the application and of the concrete visualizations, this page will present sample screenshots and sample visualizations. Later, sample analyses and videos of growing community structures will be added.

 

06/03/08 - First Screenshot using the structural Clustering Algorithm of Release 1.1 - User can cluster the original MSN instant messaging network into a desired number of groups. Structural clustering will construct partial networks by looking for the network's weakest connections. Authors are given as index numbers.

 

06/03/08 - Structural Clustering Algorithm of Release 1.1 - User can cluster the original network into a desired number of groups. Structural clustering will construct partial networks by looking for the network's weakest connections. This image shows the connected clusters (same instant messaging network as the screenshot above) by using different colours. Authors are given as index numbers.

 

 

06/03/08 - First Screenshot of User Interface of Release 1.1 - User can use video controls to view the evolvement of the selected ego network.

 


User Interface - User selects discourse - the last discourse is visualized in the background.

 


User Interface - JAVA 3D Visualization mode active - Selected node is marked red.

 


User Interface - 3D Visualization and EGO Filter to generate an EGOnet of the red node.

 


User Interface - The user interface for online importing a new Newsgroup is active.

 


Sample Structure of a PHP-related NNTP Newsgroup - The nodes are authors (labels invisible) the edges are communication relations between authors. The size relates to importance. One author dominates. Four authors connect the two clusters.
