Netvizz, a Facebook research app for extracting data from the dominant social networking service, has gained a new feature: page exploration. While the app has been able to get ego-networks and group networks from the start, this is the first time that data for pages can be extracted as well. The Social Network Importer for NodeXL already allows for extracting both co-engagement (users that comment or like the same post are connected) and bipartite networks (both posts and users are in the graph) from Facebook pages but requires you to use NodeXL and Microsoft Office on Windows.

The first implementation of page exploration on netvizz only provides bipartite network files only and yields less data on users, but adds information on the page posts themselves and outputs them both as a graph file and a simple tab-separated text file. For the moment, the app captures a user specified number of posts from the page and loads up to 1000 comments and 1000 likes. It also specifies the type of post in both of the files it generates. This is the (edgeless) network created from the last 100 posts of the New York Times Facebook page:

Users are gray, videos are blue, links are red, photos are yellow and status updates are green. Size is engagement. Because distance from the center indicates stronger engagement from non regular users, one can easily see that both photos and status updates are engaging a different audience than the links and videos.

Visualizing the data from the tsv file, we can explore these kind of relations further. Here, I used Mondrian‘s capacity to show highlights in one chart on all other open charts:

By selecting photos in the barchart, the scatterplot (x: likes, y: comments) shows that photos not only produce much higher engagement scores (the engagement value in both the tsv and gdf files combines numbers of likes, comments, shares, and likes for comments into a single metric) – the median for links is 453, but 1724 for photos – but that there is also a tendency for photos to provoke a comment/like ratio that trends toward the former. This is data from about 10 days of activity, so not suited to make any larger claims – interesting nonetheless.

As already mentioned here, the next step is to produce network files for multiple pages.

  1. This looks good Bernhard.(I use Ubuntu and Gephi) I’ll try it!!

  2. How do you compute the engagement metric?

    Thank you,

    • it simply adds numbers of likes, comments, shares, and likes for comments together…

      • Thanks. So one can retrieve the number of shares through the following formula?

        (1) engagement – full likes – full comments = shares

        or do the comment likes do not integrate the full likes, as described in the following formula?

        (2) engagement – full likes – full comments = shares + comment likes

        Thanks,
        Pedro

        • comment likes are also counted in the engagement metric!

          • Thank you very much for the answer. Just another question, I am getting this error over and over while processing a large page:

            API connection timeout. (Error message: OAuthException: (#4) Application request limit reached) Trying again

            Should I wait for it to go back to normal, should I reduce the number of posts retrieved or should I just start again and hope it works flawlessly next time?

            Thank you for such a great tool and impeccable support!

          • Nothing to do, the tool repeats the call. Before submitting a problem, please read this: http://www.chiark.greenend.org.uk/~sgtatham/bugs.html

  3. Great app! Is there any possibility to override the limit of 999 for pages?

  4. HI great app. A question about Netvizz Group feature.
    I understand that this feature maps the user interactions (when someone like or answer to a post results an edge from two user). Is it in plan to track the temporality of interactions? I mean if I interact more times with a specific user it could be ineresting see another edge, not only the first one.
    Thanks a lot

    • Hi Allessandro,

      Actually, the group feature provides friend relationships between members and not interactions, so no temporarily here. I am planning to look into group interactions as soon as I have a little more time.

      best,
      Bernhard

  5. Salut Bernard !

    “but requires you to use NodeXL and Microsoft Office on Windows.” ah ah :-) such a big obstacle !

    I’m playing with this new feat and has a few difficulties to understand how you make posts (and their types : photo, vid, link, text) appear as different colors on the graph. I’ve downloaded both the gdf and the tsv, but what should I do with the latter ?

    Thanks for help !!

    Martin
