From LinkedIn’s networking graphing service; see also my map

I’ve been digging around in graph-mining and visualization tools lately, and this use at LinkedIn is one of the few cases where such things actually break through into mainstream usefulness. Well, perhaps not useful, but it’s nice to see how groups overlap.

In my chart here, the big tight-knit, self-referential cluster on the left is Joost, the TV startup I joined in 2006/7. At the top there is another tightly-linked community: the W3C team, where I worked 1999-2005. In between is a fuzzier cluster that I can only label ‘Web 2′, ‘Social Web’, … lots of Web technology standards sort of people. Then there are the linkers, like Max Froumentin and Robin Berjon between the W3C and Joost worlds, or Libby Miller and folk from the Asemantics and Apache scene (Alberto Reggiori, Stefano Mazzocchi) who link Joost through to the Semantic Web scene in the lower right.

The LinkedIn analysis finds distinct clusters that are fairly easy to identify as “Digital Libraries (Museums, Archives…)” and “Linked Data / RDF / Semantic Web”, even while being richly interconnected. I’m not suprised there’s a cluster for the VU University Amsterdam (even though well-linked to SW and digital libraries). However the presence of a BBC cluster was a surprise; either it shows how closely-knit the BBC community is, or just how much I’ve been hanging around with them. And that’s the intriguing thing; each individual map is just a per-person view, a thin slice through the bigger picture. It must be fun to see the whole dataset…

My name is Zander Jules a Banker and accountant with Bank Atlantique Cote Ivoire.I contacting u for a business transfer of a large sum of money from a dormant account. Though I know that a transaction of this magnitude will make any one apprehensive,
but I am assuring u all will be well at the end of the day.I am the personal accounts manager to Engr Frank Thompson, a National of ur country, who used to work with an oil servicing company here in Cote Ivoire. My client, his wife & their 3 children were involved in the ill fated Kenya Airways crash in the coasts of Abidjan in January 2000 in which all passengers on board died. Since then I have made several inquiries to ur embassy to locate any of my clients extended relatives but has been unsuccessful.After several attempts, I decided to trace his last name via internet,to see if I could locate any member of his
family hence I contacted u.Of particular interest is a huge deposit with our bank in our country,where the deceased has an account valued at about $16 million USD.They have issued me notice to provide the next of kin or our bank will declare the account unservisable and thereby send the funds to the bank treasury.Since I have been unsuccessful in locating the relatives for past 7 yrs now, I will seek ur consent to present you as the next of kin of the deceased since u have the same last names, so that the proceeds of this account valued at $16million USD can be paid to u and then u and I can share the money.All I require is your honest cooperation to enable us see this deal through. I guarantee that this will be executed under all legitimate arrangement that will protect you from any breach of the law. In your reply mail, I want you to give me your full names, address, D.O.B, tel& fax #.If you can handle this with me, reach me for more details.

Thanking u for ur coperation.

I’m suprised we’ve not seen more of this, and sooner. Youtube contacts are pretty spammy, and twitter have also suffered. The other networks are relatively OK so far. But I don’t think they’re anything like as robust as they’ll need to get, particularly since a faked contact can get privileged access to personal details. Definitely an arms race…
