OK, let’s do this: some statistics and visualization of the tweets for ISMB 2012.
In previous years, when FriendFeed was used as the micro-blogging platform for the annual ISMB meeting, I’ve written a post describing some statistical analysis of the conference coverage. Here’s my post from last year.
This year, it appears that the majority of the conference coverage happened at Twitter, using the #ISMB hashtag. Here’s what happened on July 18th when I used the R package twitteR to retrieve ISMB-related tweets for July 13/14:
library(twitteR) ismb1 <- searchTwitter("#ISMB", since = "2012-07-13", until = "2012-07-14") length(ismb1) #  383
383 tweets. Here’s what happened when I ran the same query today:
library(twitteR) ismb1 <- searchTwitter("#ISMB", since = "2012-07-13", until = "2012-07-14") length(ismb1) #  0
Zero tweets. Indeed, run the same query via the Twitter web interface and you’ll see only a very few tweets with the message “Older Tweet results for #ismb are unavailable.”
So far as Twitter is concerned, ISMB 2012 never happened. Or if it did, the data are buried away in a data centre, inaccessible to the likes of you and I. Did you ever hear anything more about that plan to archive every Tweet at the Library of Congress? Neither did I. I very much doubt that it’s going to happen.
I think Twitter is great – for broadcasting short pieces of information, such as useful URLs, in near real-time. For conference coverage which benefits from threaded conversation, longer comments and archiving, I think it’s rubbish.
On July 18 I did manage to retrieve 3162 Tweets for ISMB 2012, created between July 13 and July 17. I’ll write about them in a forthcoming post. All I’ll say for now is – lucky I was able to grab them when I did.
