Presentation Notes
In my personal view-point, this paper concentrate on 2 important concept. The first one is visualization. If so, what is the information visualization? Though it’s hard to make clear definition of visualization, I believe the most important purpose of visualization is to understand something better. Undoubtedly, through the simplification and emphasis, the information visualization help for us to understand and comprehend the object better.
But, understanding what?

How vizster accomplishes its goal through visualization

Presentation Notes
And from now on I want to show how the authors accomplish their goal.

Presentation Notes
This is the screenshot of vizster. In the left panel you can see the structure of the lines and icons which consists graph. Each icon, the authors call it node, represent the member of friendster. And the line, I mean edge, show the relationship between the members. In the right panel, you can see the individual information about the selected member. Each time you clicked the member icon, the right panel exchange, and will show you the member’s information. But I think the essential function of vizster is to show the connection between the members. Who is who’s friend? That’s the main concern.
Show friends

Presentation Notes
First, you can find one member’s friends by the different saturation of member icon with mouse over action.
Connection between two members

Presentation Notes
Or, it’s possible to know the connection between two specific members.
search
Presenter
Presentation Notes
You can type the desired keyword to the text field by yourself. Or you can choose the keyword in the given criteria at the individual information panel on right side. Then, you can see the highlighted member icon which answers with your keyword. In this slide, you can see the members for the keyword, “student”.
X-ray mode
Presenter
Presentation Notes
here is the different mode of visualization which is called x-ray mode, to visualize attribute values such as age, number of friends, gender, relation status, or time since last log-in. Now, you can see the gender difference at here. You can happen to know whether someone is male or female among Amanda's friends. And the distribution of gender, too.
Community structure is differentiated by the community slider.
Presenter
Presentation Notes
Through the clustering close members, you can see the overview of the community structure. And with the dragging the community slider, you can change the state of clustering as you want.
Test
• Public installation & informal lab setting• With the early members of friendster• Explore and play• Discovery the pattern of the community• Higher level of sophistication than shown
Presenter
Presentation Notes
After development of vizster, the authors test their work through the public installation and informal laboratory setting. The public installation was took in San Francisco with the group of party-goers and early-adopters of friendster. The test in lab, the participants were also friendster members. The authors found that both group enjoyed exploring social network and playing with this tool. And during the process of discovering the pattern of the community, the participants re-produce the story about the community. In this way, they tends to give a higher level of sophistication to the community analysis that is shown. As a result, the end-users of vizster use this tool to explore and play with their networks. Until now, I summarize this paper. And from now me and 3 panel will discuss about the related issues.

Social Network
Presenter
Presentation Notes
First issue is social network. In the paper, social network service is the important subject matter. If the info-vis is the process of discovering the pattern object, it is important to extract the characteristics of the object. For this, we need to understand deeply about social network itself. That is why we need to know better about social network.

And the second one is the information visualization. Basically, the vizster is the visualization tool. For this reason, to find the multiple aspect of the vizster, we need deeper understanding about the information visualization. Vizster is the complex combination of the various kind of info-vis methodology. and with this discussion, it is possible to recognize the outstanding point of vizster an a visualization to for social network.

Presenter
Presentation Notes
Untill now, we discussed about the info-vis and the social network. So, what is beyond vizster? Maybe, another assemblage of the info-vis and the social network will be emerge. I think it’s inevitable to consider about the use of social network visualization as a summary of our whole discussion.
