LJ Metro Concentrations

Jan 20, 2009 03:40

I've collected about 57,000 cities from a city field found in LJ user foaf feeds. This field has its problems. It might be blank 90% of the time, people write mumbo jumbo in it, and people often write the same city's name more than one way. Still, it can sense large city names.

#1: Moscow! )

So basically if I'm looking for people outside USA and Russia... I should look elsewhere? :P

Take another look at the top four cities. One of them isn't in the US or Russia. :P

1783 | Moscow
346 | Seattle
205 | San+Francisco
202 | Toronto

For that matter, London plus Melbourne together would place at #3.

I'm curious what time-frame the foaf feeds call "active".

Moscow is not in Russia?
Where did San Francisco go if it's not in the US?

Toronto is in Canada (not the U.S. or Russia), is what the above commenter was saying.

Right. I misread his reply. Twice haha. I guess I need new bifocals. Thanks for pointing that out. Though I knew that, this time I read their reply right. ;)

I'd say Seattle is closer to being Canadian than Toronto is.

You're from Vancouver originally, aren't you?

Ha ha sly Canada!

You know, I have heard that Singapore is a major country for LJ... and I have seen clues of this... I was surprised when I couldn't find any cities there. Hmm.

I call active... it's a pragmatic definition but it should make sense... I sample LJ post count as frequently as every 60 days. So it's probably true that some time in the last 3 months or so, two samples at least 60 days apart detected the same post count. I do not trigger a review because I don't sense how old the old samples are... but I would say that contributes to accuracy, at the cost of some currency. I do walk a large LJ map pretty fast, however, and consider pulling a foaf sample (if the old one is older than 60 days) whenever i pull an fdata sample. all of this is limited by the fact that i really just started tracking data 3 months ago.

There are other problems with this (and some people's post count is lower, if they went on a post-killing spree), but it is a pretty good sensor of an inactive LJ, do you think?

Why would you put London and Melbourne together though?

Because there is a Melbourne in England too.
