Modern Art / OCLC Network in TouchGraph

Since putting together the New York Times identity network, I’ve wanted to look more closely at a larger network of art identities and subjects. I reworked some of the OCLC pipes that pull related identities and associated subjects from an Identity page to output something a bit closer to a TouchGraph data file, wrapped the whole business in a processing sketch, and had it crawl 100 objects from the Met’s Modern Art department.

After some data cleaning, the network contains,
~3,500 nodes = 1,200 related identities + 2,200 associated subjects + 100 Modern Art Records and
~7,200 edges = 1,700 -> related identities + 5,500 -> associated subjects

Data files – Nodes (Tab delimited), Edges (XLS, Tab), Identities only X3D model

The same terms can appear as related identities and associated subjects. As in the image above, Jasper Johns the associated subject is selected, while the identity is in the upper left. I’ve color coded the nodes in the graph (blue identities, gray subjects) and they are distinct in the data.

For a network this large, TouchGraph works well a single node at a time, but extending the locality stressed out my machine and I still wanted to see the whole network. Pajek to the rescue. Below is the 3D force-based layout of only the identities.

Better, but I still wanted a closer look. Pajek exports to X3D.
Used Octaga to render; took a quick screencast…

Directionality is missing from the images but the edges only go from the numbered nodes (the starting set of Met Modern Art records) to Identity records from OCLC.

The major nodes are those you might expect. Each associated subject is presented in a tag cloud on the Identity page with a variable font size. I’ve used those sizes as edge weights where appropriate and summed them across the network here.

(Ahem, Metropolitan Museum of Art appears only 3 times in the network.)

I’ve started looking at the network metrics in UCINET and Pajek but I think there has to be something said about validity at this point. What we have is a two-mode network, i.e. a bipartite data set. Not a problem; plenty of ways to look at the data. But this is more an artifact of the data collection method than reality. Object records don’t point to one other and, since I didn’t iterate, there are no connections between the collected nodes. Of course the validity of the whole data set is pretty dubious. My selection criteria were intentionally broad and uninformed – picking the top 3 identies from OCLC and then pulling in everything, ignoring rank and weight in the data collection phase. The initial goal of the pipes was to find out more about the quality of the results from OCLC – to see if a simple query would suffice. So the pipe structure will need to change if we want validity. I don’t know nearly enough about how associated subjects are mapped to identities, or how an identity is “related” to any others, or for that matter how complete the coverage is for Modern Art in OCLC. Ultimately, any analysis will be saying more about the OCLC data surrounding books rather than about the Met’s holdings. I’ll be sure to present the network analysis metrics on a more “complete” dataset.

With all of that criticism about lack of rigor out of the way; Wow. With a large enough starting set, the resulting network gets rid of the noise pretty well. I think this network is a good place to start with clear direction for improvement.

Dear  President Obama,

I just finished reading Elizabeth Kolbert’s article in June 29 2009 issue of The New Yorker called “The Catastrophist,” a profile of climatologist James Hansen.

I have thought many times about how to compose any kind of letter that would at least have meaning to me, if not to the administration, but time has run out for pondering.

I am an artist and animator, and I work with issues of climate change (
I have had more conversations than I care to remember about how it’s almost too late, how it is too late,  how it is futile and hopeless because of big business and lobby resistance. But time has also run out for conversations, and people like me need to DEMAND a message from you and a commitment to action.

Respectfully: What is the plan? When do you declare, as I believe is appropriate, an impending state of emergency? When does government step in and help save humans and other beings from a change so drastic, we will all suffer greatly? Health care, bank bonuses, better education, none of it will matter if we don’t make some serious changes in the way we manage the planet – from fuel production to consumption.

I know this is not the most eloquent letter, but I need to hear from you. I am frightened for myself, my friends, for people I know in vulnerable places, and for all the children I know whose lives will soon be altered beyond comprehension.

I wrote  and sent this letter last night out of complete exasperation. I’ve been feeling a murky disappointment about the murky attention being paid to climate change, and everyone says “be patient; Obama’s Admin’s hands are full.” I really hope that if you’re reading this, you’ll consider writing too.  A mediocre “cap and trade” bill got passed by the House (and even this has faced enormous resistance by both libertarians and big business) . We are at the end of the hourglass (some experts think time’s up already), and I have gone from helpless despair, to trying to exercise conviction that my small actions will make difference, to realizing it’s only pressure on government to legislate  fuel change, energy innovation and radical shifts in global behaviors. Pundits  opine that scientists don’t understand the way politics work when they state that we have a small window of time in which to slow down or somewhat restabilize the PPM of CO2 in the climate IF we shut down ALL coal plants;  but Hansen “argues that while the laws of geophysics are immutable, those of society are ours to determine.”

If you have any suggestions on how to effectively(?) reach others in gov with individual letters, please post.

Speaking at Dorkbot PDX, August 9th

Marisa Olson and I are speaking at Dorkbot PDX this Sunday, August 7th, 7PM. The annoucement says:

We are extremely honored to have two distinguished artists from New York visiting Portland and sharing their work with DorkbotPDX. Please help us welcome these amazing and inspiring dorks from across the way!

I’m flattered to be called distinguished… !

I’m very grateful to Amber Case for patching us into the PDX scene, and Thomas Lockney and Jason Plumb for setting up this opportunity to share with some PDX dorks.

While installing a temporary station near Death Valley this summer, we met with Dr. David Dubois, air quality expert at the Desert Research Institute in Las Vegas.

Listen to Dr. Dubois discuss some of the important air issues in the great basin:
