VNA open data file for all CCK09 forums released

Extract the .vna file and open with NetDraw (196.56 KB)

social network of CCK09 Moodle forums


  1. I just found your blog two days ago and have been reading the archives. I have been trying to read LMS discussion board data for SNA myself, and just found SNAPP two and a half days ago. I'm particularly interested in your workflow in this post:
    steps 2 and 3. I find the same problem in having to sum up the vna files for threads within a module. I haven't worked out a good solution--the Ucinet time stack seems an option, but I want the strength network and not the talk network. If I read the vna file into NetDraw, select the Strength attribute and then export from Netdraw to Ucinet format, maybe I can time stack strength networks within a forum. I'm interested in how you worked out the aggregation of networks within a forum and the union of those fora for the whole course. If you have something written, or just some thoughts to share:
    Interesting work in your blog.

  2. Hi scot,

    Thanks for your comment. I will post my manual method and some scripts in the blog. I am also looking at how gephi can be used to merge datasets from Snapp using the exported graphml. I'll post the results on the blog.

    Unfortunately both still involve a lot of manual methods. I think a script could be made such that you simply feed it the moodle forum urls and it will output a union dataset. But my programming skills are not good enough to do that. The only thing I can do is probably to come up with pseudo code.

    Anyway, I'll try to post my latest workflow for CCK09 ASAP.
