More and improved Vizster
Over the last days, I spend some more time working with Vizster.
I got the importing of new data sortof automagically. Well, less to just a few easy steps. I could make it totally automagic, but I’m a bit hesitant to automate the process of adding new users, as it adds a lot to the database, so I would like to keep some control on it. so I leave it at this for now.
And, what’s nice, I got avarars for users working! The network I use has an API, and I could get avatars for users. Since I can compile the Vizster source now, I could change where it looks for icons to my own script, that loads them from the API.
I hope to one day get it to run as an applet instead of as an app, but my Java is a bit rusty (the small changes I made sofar have been harder than I hoped..).
Is there a working copy of Vizster out there? I have read about it, seen examples of it and it looks very powerful and useful. I have been to his website and seen the projects but can’t get anything to work.
Any thoughts pointing me in the right direction would be appreciated.

Well, working as in: It compiles
It needs a database to connect to (If there is demand, I can make a dump of the DB schedule). I don’t know any public sources for data for this database: I build my own scraper (and won’t publish my current dataset).
I guess you did find the vizster sources at http://sourceforge.net/project/showfiles.php?group_id=98962 ?
Any more questions are welcome.
Btw, you’r the first comment here, ever! Yay!
Hello Martijn,
I’m planing a platform for online community and found information about Vizster. Can you tell me what kind of database is necessary for vizster to work properly.
Thanks for your answers,
Sabina
It uses a MySQL database. I’ll post the DB schema (just 2 tables) this week.
I don’t think you’ll need to plan your platform around it: you can generate this data from any platform (or, with a bit more work, modify vister to fit your platform).
Thank you for your reply.
Hi,
I’m looking for a database script in order to run the vizster code on my local machine. Do you know where can I find one ?
tks.
I’m not quite sure what you mean with “database script”. If you’r looking for the DB tables setup: I posted that in another post, which can be found at http://martijnpannevis.nl/blog/2008/01/15/vizster-db-schema/
Tell me how to login vizter
I don’t have account n where to get it
I’m looking for the db data set. If not possible please give some directions on how to fill the tables by crawling internet. Please share crawler source code.
Hi, I am trying to modify Vizster for a student project by adding differents social networks support, and I haven’t be able to find any information on the graph input format used. What exactly have you been able to do ? Would you have a sample of xml graph file to give as an input to Vizster ?
Thanks!

I didn’t have Vister read files: It connects to the MySQL DB host directly. The DB schema is on another post at this blog at http://martijnpannevis.nl/blog/2008/01/15/vizster-db-schema/
It should be possible to modify vizster in a way that it does read files; If you build this, please let me know.
@sajan I only have an old dataset for my friends, but with the DB schema, you can build your own scraper, depending on your social network.
@icang99 there is no place to login: Vizster is software that you download (and non trivial to setup). Maybe one day I’ll build it as a service…
I Martin,
Very useful. Afetr download and put the vizter into eclipse project I got:

What I did wrong?
Do you know what kind of file I is “C:\vizster\lucene\segments”
Could you help me?
Thanks in advance.
