Crowdsourcing in action: results

| No Comments | No TrackBacks | ,

I was writing about a pilot the Library of Congress was doing with Flickr. I measured also number of tags, notes and comments and repeated the process several times during last 2 months. Here are some numeric results:

Library of Conress pilot on Flickr

As expected, while tags, notes and comments still coming, in general the lines are almost flat after 50 days.

Averages: 4.85 unique tags,  0.39 notes, 1.34 comments per photo.

The Library of Congress blog shared some real results:

And because we government-types love to talk about results, there are some tangible outcomes of the Flickr pilot to report: As of this writing, 68 of our bibliographic records have been modified thanks to this project and all of those awesome Flickr members.

Well, that doesn't impress much, but they must be happy as they have posted 50 more photos.

The Library of Congress has launched an interesting pilot project with Flickr, which can be characterized as a crowdsourcing experiment.

They have uploaded 3115 copyright-free photos from two of the most popular collections and in return they hope the Flickr community will enhance the collections by labeling and commenting images:

We want people to tag, comment and make notes on the images, just like any other Flickr photo, which will benefit not only the community but also the collections themselves. For instance, many photos are missing key caption information such as where the photo was taken and who is pictured. If such information is collected via Flickr members, it can potentially enhance the quality of the bibliographic records for the images.

Crowdsourcing is a special case of a human-based computation, a technique for solving problems that computers just incapable of (or if you wish - problems for which humans cannot yet program computer to solve). The simple idea behind human-based computation is to outsource certain steps to humans. And if you outsource it to the crowd you get crowdsourcing:

Crowdsourcing is a neologism for the act of taking a task traditionally performed by an employee or contractor, and outsourcing it to an undefined, generally large group of people, in the form of an open call. For example, the public may be invited to develop a new technology, carry out a design task, refine an algorithm or help capture, systematize or analyze large amounts of data (see also citizen science).

  Think about tagging images (Google Image Labeler), answering arbitrary human questions (Yahoo! Answers), selecting the most interesting stories (Digg, reddit), inventing better algorithms (Netflix prize) or even monitoring the Texas-Mexican border.

Btw, did you know that Google didn't invented Google Image Labeler, but licensed Luis von Ahn's ESP Game? And that while the crowd is working for free on Google Image Labeler, improving Google's image search, Google never shares collected tags? I don't think that's fair. Moreover I think that's unfair. Results of crowdsourcing must be available to the crowd, right?

Anyway, how is the pilot going? From the Flickr blog we learn first results:

In the 24 hours after we launched, you added over 4,000 unique tags across the collection (about 19,000 tags were added in total, for example, “Rosie the Riveter” has been added to 10 different photos so far). You left just over 500 comments (most of which were remarkably informative and helpful), and the Library has made a ton of new friends (almost overwhelming the email account at the Library, thanks to all the “Someone has made you a contact” emails)!

That was after 24 hours. Today, 10 days later the results (according to my little script) are: 2440 comments, 570 notes, 13077 unique tags.

That's almost 500% more comments and 300% more tags. In average 0.8 comments and 4.2 tags per image. Not bad, but not very impressive too. I will be interesting to check it again in a month to see what's is the trend.

It's also interesting to see when bad guys start to abuse it. Google Image Labeler was abused less than a month after its launch. And Google Image Labeler is protected from abuse by using only tags selected by both players independently, while on Flickr there is no protection whatsoever.

I also figured out that while these 3115 photos were posted to Flickr, there are about 1 million others available online in the Library of Congress's own Prints & Photographs Online Catalog, which is really astounding. Check out this picture of General Allenby's entrance into Jerusalem back in 1917:

Scanned from b&w film copy negative, no known restrictions on publication, freely available as uncompressed tiff (1,725 kilobytes). Now that's real wow.

New camera new pictures new life

Seems like my wife has found the hobby of her life. She's all about photography now. Books, sites, forums. She's overgrown our little but powerful Canon S70 and got new shiny (not really shiny, but a black one) Canon 400D (aka XTi). S70 is finally mine again!

Here are some her first pictures taken with Canon EF 50mm f1.4 Lens:

The photos are taken by Alenka, my wife. I think she's outgrown out little Canon S70 and needs some SLR camera. Anybody has any advices for buying first digital SLR thing?

Flying over Tel-Aviv

This is a great picture my wife took. It's Tel-Aviv beach view from a landing plane. Speaking of Tel-Aviv, we've got something unusual happenning here. There was a tornado near the beach and UFO over the city. Btw, I believe I've seen that tornado while driving to work via Tel-Aviv.

 Remember this famous Mars face? So recently NASA found another one, here in the Earth, in Australia actually. They call it "Ghostly Face In South Australian Desert". I first though it's about upside-down face that reminds Dali paintings, but no. Can you see a ghost face here? That's really stupid, but still cool picture. Btw, if you are not yet subscribed to the NASA Earth Observatory you might want. They publish some really cool pictures every week.

Hibiscus time

| No Comments | No TrackBacks |

Hibiscus blooms again at our home. Actually outdoor it blooms non stop all year here in Israel, serving as a perfect undemanding but beautiful hedge. It's everywhere, every color and every form, there are even Hibiscus trees. But my home Hibiscus blooms two or three months in a row, then rests for couple months and blooms again. Every flower lives only day or two. Short but bright life.
