I can’t download my historic posts beyond the most recent 3,200, but Gnip can (presumably with Twitter’s full blessing) sell access to people wanting to use sentiment analysis for stock trading.
Gnip is announcing a new product today that provides access to the full database of public tweets from the beginning of time — or rather, the beginning of Twitter.
…The new product, called Historical PowerTrack for Twitter, has been in testing with customers including Esri, Brandwatch, PayPal, Brandwatch, Waggener Edstrom, Network Insights, Union Metrics. Moody says this data opens up a number of new use cases. For one thing, financial firms are developing trading algorithms that incorporate Twitter data, and they can now test those algorithms on data from the past — in other words, if they think they can use social network activity to predict of stock market activity, they now have a giant database for seeing whether that’s true. Moody says there are also academic researchers looking at the impact of Twitter activity on the Arab Spring.
“We fundamentally believe that social data is going to be in every application. We’re only at 1 percent of the journey.”
I’ve noticed a couple of Tumblr blogs recently that use images posted in the Text post type, rather than the Photo type. This is particularly annoying when you’re trying to determine image attribution.
Generally I run across them through ffffound. Here’s an example: it’s a nice picture, but I want to credit it more thoroughly than just linking to the blog on which everyone saw it. I head over to the Tumblr and open the archive page, and I get this:
Of course, Tumblr somewhat encourages other anti-attribution patterns: images being reposted to ffffound from people’s dashboards is one of the more obvious ones. Still, it’d be nice if people avoided adding to them.
It’s already the time of year when people look back and try and pick out the best of the year. If you’re inclined to do that with the photos you’ve posted to Flickr, here’s a good way.
The search function has three key features that make this work. Firstly, the “interestingness” (a somewhat arbitrary, but still useful, measure of how, well, interesting a photo is) is available as a criteria for sorting. Secondly, there are ways to filter by time (either by date taken, or by date uploaded). Thirdly, you can limit photos to your own photostream.
Putting that all together gives you a this URL: http://www.flickr.com/search/?q=&m=text&s=int&d=taken-20100101-20101231&w=me
The arguments, from right to left, make it search through all photos (that’s the q=, an empty query), in text mode (as opposed to tag mode), searching by interestingess, taken between the dates specified, and limited only to photos by “me” (which magically maps to the logged in user). If you’re tempted to find a best photo from those you’ve uploaded this year, why not use that as a starting point?
