Visualizing the Flickr social network

view profile

GustavoG says:

I just posted a set of five graphs depicting the Flickr social network at various levels of resolution.

I used the same data as in the previous analysis of Flickr demographics, exactly one month ago. I guess a lot has changed in this month, but the results are probably still relevant.

The main observations are that while the Flickr social network (measured by mutual contacts) is very tightly-knit, there are "clusters", or "regions" in FlickrLand. Globally speaking there are four clusters: one including the staff and several "old timers", a very large cluster including most of the network, a third cluster including mostly people from UAE, and a fourth small cluster, mostly linked with the staff and old-timers, that I don't really understand. striatic - I'm sure you can explain it readily.

It would be interesting to map onto this network cross-sections of the Flickr population, e.g. members of FlickrSocial, or the group of people that ever posted anything in FlickrCentral, etc. While browsing the network at the highest resolution, I saw large areas full of people that I haven't met so far.

I encourage you to look at the full resolution of the images, to be able to read the names, otherwise it's very hard to make much sense of it.

Have fun! :)

PS edit: if you have time to look at just one, this is it:
mc-50 spread
...but I encourage you to look at the progression in the whole set, to get a better feeling for the whole network.

The fourth cluster, containing names like joi, marccanter, anildash, plasticbag, lia etc, can be named the "Blogger Cluster"

There's a lot of interesting things there. One I just noticed is that you can see who the "ambassadors" are - people who are well-connected to people in different clusters. Striatic for example makes a good ambassador between the main Flickr cluster and the old-timers, as does txkimmers. Likewise, a user named dhabyani seems to exist between the UAE crowd and the main cluster. Sure enough, looking at their profile, they have a good mix of UAE folks as well as general Flickr people.

striatic is a group administrator striatic says:

yes .. the 'edge nodes' are interesting .. i'm right between the main cluster and the GNE cluster .. creeping slowly towards the main group.

the people in the center of the clusters are interesting too.

in the middle of the "neterati" cluster you've got your "doctorow" and "anildash", "plasticbag" and "marccanter"

in the middle of the GNE cluster, you've got your "ellipse", "ricardo", "kallese" and "loliinspired"

"caterina" and "stewart" are nodes between the GNE and neterati clusters.

then, over in the main cluster, you've got your "fubuki", "efatima", "ivonne", "tamaki"and "auntiep"

the UAE cluster i don't know very well, but recently hyper-gemini, at the core of that group, dedicated a set to me and made me a contact .. so, might the network fold in upon itself over time?

interesting stuff.

How did you map the users into the 2d space? (Just addressing the fact that there are many ways of representing a grpah in 2D.) Why is, for example, warrenellis an outlier? (I know who he is, but why does he happen to be on the edge? Was this a conscious choice?)

Yes, I have thought it would be interesting to see what FlickrCentral looks like, also FlickrSocial.

How did you map the users into the 2d space?

I used two different programs to visualize the network, both gave virtually the same result. The graphics I posted were created using yEd Graph Editor, with the "organic" layout algorithm.

The requirement of no overlap between nodes causes all kinds of distortions, including throwing some nodes way out like you noticed. A bit misleading, but a must, to be able to visualize anything at all.

So what conditions in your real life determine where you will land on this map and who you will be connected to?

I started mucking about with Flickr almost a year ago. I never played GNE, I just met the core GNE group in chat--that is also how I met striatic. I don't blog, I am not a social software inuit. It really makes sense to me to be where I am on this map too.

I do find it interesting that what looks like the base of the network, the fat main Flickrland cluster, is not the source of its origin. I only say that because I recognize the older accounts among the GNE'ers and the bloggers.

It would be very cool to see a visual timeline of the growth of the overall network.

Good question, and I have no idea what the typical answer would be.

In my case, I would be in the vicinity of the fotolog.net subcluster even though never used fotolog. I guess that my aesthetic preferences made me gravitate towards some people in that area, which guided me to contact their contacts.
I guess that's also why I didn't recognize it as "the fotolog.net subcluster" - that's where I am, but not for that reason. :)

Thom Watson says:

I ended up pretty much smack dab in the main Flickr cluster, next to Special and just a couple of node diameters away from fubuki. If things had gone a little differently in my life just a few years back when I was riding the dot-com curve (unfortunately, up only briefly and then rather quickly down into implosion) before becoming a federal wage slave in the end, I might have ended up in the blogger cluster with the blogerati; as things turned out, though, I know them but they don't know me.

Interestingly, what I haven't yet seen here in Flickr is the formation of a queer cluster; while there does seem to be some mutual linking from participation in the "Ecce, Homos" and "LGBT" groups, it apparently hasn't reached a large enough mass of interconnectedness to be recognizable separately from the main cluster at the 50-contact level yet.

txkimmers says:

girls can be queer too, can't they? Unless queer is gender-specific in a way that I didn't know about.

Gustavo, I have been thinking about these Flickr metrics of yours, and how to link them to other measurable factors in my life. Specifically, the 15 lbs. I have layered onto my tuchus due to inordinate time spent Flickring.

If I used my mutual Flickr contacts as X, and the pounds packed on as Y, then I might be able to measure the caloric density of each contact, no?

Although, as I have a closer relationship with some contacts vs. others, then the caloric density would vary as well. My friends and family would definitely be more fattening than new contacts, obviously.

And for those whose friendship has extended into the world of IM, well you are all just big human chocolate fudge sundaes, arentcha?

This is depressing, I am going to go work out.

there seems to be a mini gay (male) cluster that comments on violentz's photos. not yet on gustavo's map, but it will probably appear eventually. after i commented on one or two of violentz's photos, i suddenly had a couple of gay men add me as a contact--don't think it is a coincidence (they also comment on violentz's pics).

j david says:

very impressive work!

if we had a measure of strength of connection, we could be onto something very cool!

for example, it is the edge players (assuming that they are strongly connected to others in the clusters
that also have strong connections) that are the real networkers. (they have the fewest connections into the existing clusters, and more out into the flickr ether) These folks could be the "attractors" that give rise to new clusters.

or not- it all depends on a few more factors not capture yet

very stimulating!!!

thanks to all!

GustavoG says:

Strength of connection... I thought of playing with weight of connection in two ways, one strengthening it, the other weakening it.

Strengthening: the more shared groups, the more the two users comment on each other's photos, etc. Ah, the things one could do with direct access to the database... :)

Weakening: If I have "just" fifty mutual contacts, perhaps each should be weighted higher than if I had four hundred mutual contacts. The intuition would be that everything else being equal, the more people I socialize with, the less I'll be able to socialize with each of them. (In Spanish, "quien mucho abarca, poco aprieta".)

Combining both could yield very nice results, and might unravel a bit the too-tightly-knit center of the network, which is due mostly to very highly-connected people.


On another topic, last night I uploaded this Flickr social network visualization stuff, and today Flickr Graph, a Flickr social network visualization tool is published (and even makes it to the Flickr Blog).

Is this one major Flickr coincidence, indicative of... what?

....i'm like all, am i popular or what?


I analyzed the raw data: www.flickr.com/photos/gustavog/sets/113313/

…provided by gustavog and equated the results by categorizing his clusters into popularity subgroups as defined by characters in the breakout movie of the 1980s, THE BREAKFAST CLUB:


the Brian Johnson(s) as played by Anthony Michael Hall:
www.flickr.com/photos/gustavog/4499381/in/set-113313/


The Claire Standish(es) as played by Molly Ringwald
and the Andrew Clarke(s) as played by Emilio Estevez:
www.flickr.com/photos/gustavog/4499392/in/set-113313/

The Allison Reynolds as played by Ally Sheedy
www.flickr.com/photos/gustavog/4499404/in/set-113313/

Then finally the bottom of the flickr popularity food chain (hello where I fall in duh!):
The John Bender(s) as played by Judd Nelson:

I for one would like to be able to use connectivity information to explore other parts of the Flickrverse:

Go to parts of the network that I haven't been to before and see different collective tastes in photography. Investigate small circles of friends with unusual perspectives, see family circles, groups of college friends, special interest groups.

One might find gold in these explorations, or at least a little entertainment!

Well, time to go outside and do a long exposure. I see some neat clouds in the night sky.
