Marc Parry has an excellent article at the Chronicle of Higher Ed about using crowdsourcing to make archives more digitally useful:
Many people have taken part in crowdsourced science research, volunteering to classify galaxies, fold proteins, or transcribe old weather information from wartime ship logs for use in climate modeling. These days humanists are increasingly throwing open the digital gates, too. Civil War-era diaries, historical menus, the papers of the English philosopher Jeremy Bentham—all have been made available to volunteer transcribers in recent years. In January the National Archives released its own cache of documents to the crowd via its Citizen Archivist Dashboard, a collection that includes letters to a Civil War spy, suffrage petitions, and fugitive-slave case files.
Marc cites an article [full text] in Literary & Linguistic Computing that found that team members could have completed the transcription of works by Jeremy Bentham faster if they had devoted themselves to that task instead of managing the crowd of volunteer transcribers. Here are some more details about the project and its negative finding, based on the article in L&LC.
The project was supported by a grant of £262,673 from the Arts and Humanities Research Council, for 12 months, which included the cost of digitizing the material and creating the transcription tools. The end result was text marked up with TEI-compliant XML that can be easily interpreted and rendered by other apps.
During a six-month period, 1,207 volunteers registered, who together transcribed 1,009 manuscripts. 21% of those registered users actually did some transcribing. 2.7% of the transcribers produced 70% of all the transcribed manuscripts. (These numbers refer to the period before the New York Times publicized the project.)
Of the manuscripts transcribed, 56% were “deemed to be complete.” But the team was quite happy with the progress the volunteers made:
Over the testing period as a whole, volunteers transcribed an average of thirty-five manuscripts each week; if this rate were to be maintained, then 1,820 transcripts would be produced every twelve months. Taking Bentham’s difficult handwriting, the complexity and length of the manuscripts, and the text-encoding into consideration, the volume of work carried out by Transcribe Bentham volunteers is quite remarkable
Still, as Marc points out, two Research Associates spent considerable time moderating the volunteers and providing the quality control required before certifying a document as done. The L&LC article estimates that RA’s could have transcribed 400 transcripts per month, 2.5x faster than the pace of the volunteers. But, the volunteers got better as they were more experienced, and improvements to the transcription software might make quality control less of an issue.
The L&LC article suggests two additional reasons why the project might be considered a success. First, it generated lots of publicity about the Bentham collection. Second, “no funding body would ever provide a grant for mere transcription alone.” But both of these reasons depend upon crowdsourcing being a novelty. At some point, it will not be.
Based on the Bentham project’s experience, it seems to me there are a few plausible possibilities for crowdsourcing transcription to become practical: First, as the article notes, if the project had continued, the volunteers might have gotten substantially more productive and more accurate. Second, better software might drive down the need for extensive moderation, as the article suggests. Third, there may be a better way to structure the crowd’s participation. For example, it might be practical to use Amazon Mechanical Turk to pay the crowd to do two or three independent passes over the content, which can then be compared for accuracy. Fourth, algorithmic transcription might get good enough that there’s less for humans to do. Fifth, someone might invent something incredibly clever that increases the accuracy of the crowdsourced transcriptions. In fact, someone already has: reCAPTCHA transcribes tens of millions of words every day. So you never know what our clever species will come up with.
For now, though, the results of the Bentham project cannot be encouraging for those looking for a pragmatic way to generate high-quality transcriptions rapidly.

The Sunlight Foundation is crowdsourcing the identification of lobbyists from photos of them at Congressional hearings and other such events. The aim is to get a better sense of the lay of the land. The first round is a hearing on the merger of AT&T and T-Mobile (because lord knows all that competition is driving telecommunications prices into the ground!). Go here for the photo and instructions. (And a tip of the hat to BoingBoing.)
Watch volunteers jump into and around the Google spreadsheet that’s coordinating the transcribing and translating of Egyptian voice-to-tweet msgs. Not exactly a Jerry Bruckheimer video, but the awesomeness of what we’re seeing crept up on me. (Check the link to the hi-rez version after you’ve read the TheNextWeb post; otherwise you can’t really see what’s going on.)

It’s mainly user-moderated. As an example, Scott takes us through the steps for the Cheezburger site.
First, the home tab where you can submit content. The LOL builder makes it easy for users to add captions to images. They get 300,000-500,000 submissions to their network every month, but they only publish 1-2 percent. How do they cull? There’s no secret sauce, no magic algorithms. It’s a four-step human process.
Step 1: All submissions are screened by an editor, looking for image quality (not taken on a cellphone at night, etc.), appropriateness (no nudity, violence, racism), germaneness (a dog photo submitted to the cat site?), and keeping photos of humans out. Most of what gets submitted is junk, and gets screened out.
Step 2: Using the second tab, users vote or add a submission to their favorites. They also look at which content has been shared on social networks.
Step 3: User screening for offensiveness and copyright violations.
Step 4: Editorial curation.
They tried outsourcing it, but there’s too much specific to our culture, and requires too much editorial judgment.
Scott shows us his the favorite photos in his own account profile. ([Some very funny ones.]
There are reports of a new type of cloud, one that is not currently in the official International Cloud Atlas. Or, possibly, it is a formation that’s been around forever, but the scattered reports are only now coalescing thanks to the Net.
According to Amazon’s review of Richard Hamblyn’s The Invention of Clouds, we only began thinking clouds could be categorized in 1802 when Luke Howard started giving public lectures. The very idea that clouds — the paradigm of uncatchable — could be divided into groups was (apparently) fascinating and thrilling. (Lamarck had also categorized clouds, but it didn’t catch on.)
A quick googly scan makes it seem that the cloud taxonomy is pretty messy. For example, the University of Illinois’ “cloud types” page lists four broad categories, and a list of miscellaneous clouds, each of which is categorized under one of the four basic types, evoking a “Huh?” reaction from at least one of us. The cloud taxonomy page at Univ. Missouri-Columbia lists eight types. Do you categorize by what they look like, how high they are, what they do (rain or not?), which celebrity profiles they resemble …? Categorizing clouds is truly a Borgesian task.
And, dammit, wouldn’t you know? Here’s a poem by Jorge Luis Borges called: “Clouds (II)” (with the line-endings probably removed):
Placid mountains meander through the air, or tragic cordilleras cast a pall, overshadowing the day. They are what we call clouds. And their shapes are often strange and rare. Shakespeare observed one once. It seemed to be a dragon. That one cloud of an afternoon still kindles in his words and blazes down, so that we go on seeing it today. What are the clouds? An architecture of chance? Perhaps they are the necessary things from which God weaves his vast imaginings, threads of a web of infinite expanse. Maybe the cloud is emptiness returning, just like the man who watches it this morning.
(translated by Richard Barnes. B; Robert Mezey; Richard Barnes. “Clouds (II). (poem).” The American Poetry Review. World Poetry, Inc. 1996. HighBeam Research. 11 Oct. 2009 v)
More Borges poems…
The Encyclopedia of Life is encouraging citizen contributions to its experts-vetted pages, so far with what seem like excellent results. There’s a good article about this at Science Daily. After two years, they’ve got 150,000 species pages underway, with 1.4 million stubs awaiting drafting.

Steve Myers at Poynter has a good story about NPR’s crowd-sourcing Dollar Politics project. One element of it was a request for help identifying 200 people who attended a Senate hearing, some percentage of whom were lobbyists.

TED has started a great new project: Distributed translations of TED Talks. Taking a page from Global Voices, it’s crowd-sourcing translations.
This is exactly what should happen and is a great solution for relatively scarce resources such as TED talks. Figure out how to scale this and get yourself a Nobel prize.
By the way, TED has also introduced interactive transcripts: Click on a phrase in the transcript and the video skips to that spot. Very useful. And with a little specialized text editor, we could have the edit-video-by-editing-text app that I’ve been looking for.

MIT will be 150 years old in two years. So, the MIT Museum (where you can see Judith Donath’s arresting and provocative info-overwhelm installation, which opened last night) is asking the public to nominate objects to put on display. The nominations themselves will remain online forever after as a very different sort of permanent display.

Just a reminder: MyFairElection.com is asking people to sign up to report on the conditions they find at their local polling place so that the site can create a “weather map” of electoral fairness.
