reCAPTCHA: Stop Spam, Read Books: A CAPTCHA is a program that can tell whether its user is a human or a computer. You’ve probably seen them — colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from “bots,” or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that’s not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into “reading” books.

To archive human knowledge and to make information more accessible to the world, multiple projects are currently digitizing physical books that were written before the computer age. The book pages are being photographically scanned, and then, to make them searchable, transformed into text using “Optical Character Recognition” (OCR). The transformation into text is useful because scanning a book produces images, which are difficult to store on small devices, expensive to download, and cannot be searched. The problem is that OCR is not perfect.

reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.

But if a computer can’t read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here’s how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.

Currently, we are helping to digitize books from the Internet Archive.

Identify Galaxies Using Spare Wetware Cycles: “hazem invites us to have fun, learn about galaxies, and actually help astronomers by looking at pictures of galaxies and identifying the type. Warning: it’s more addictive than Tetris. From the site: ‘GalaxyZoo… harnesses the power of the internet — and your brain — to classify a million galaxies. By taking part, you’ll not only be contributing to scientific research, but you’ll view parts of the Universe that literally no-one has ever seen before and get a sense of the glorious diversity of galaxies that pepper the sky. Why do we need you? The simple answer is that the human brain is much better at recognizing patterns than a computer can ever be. Any computer program we write to sort our galaxies into categories would do a reasonable job, but it would also inevitably throw out the unusual, the weird and the wonderful. To rescue these interesting systems which have a story to tell, we need you.’

Ancient Rome rebuilt, virtually: “Blog: A team has just unveiled a sprawling 3D digital simulation of the ancient city as it appeared at the height of its development as the capital of the Roman Empire.”

[…]

Not only was Rome not built in a day, but a digital model took 10 years to construct. A team of archaeologists, architects and computer specialists from Italy, the United States, Britain and Germany has just unveiled a sprawling 3D digital simulation of the ancient city as it appeared at the height of its development as the capital of the Roman Empire.

They are calling it the largest, most comprehensive simulation of a historic city ever created.

“Rome Reborn 1.0,” based at the University of Virginia, shows almost the entire city within the 13-mile-long Aurelian Walls in 320 A.D., when Rome was the multicultural capital of the Western world. Visitors can navigate through key sites such as the interiors of the Roman Senate House, the Colosseum, or the Temple of Venus and Rome, the ancient city’s largest place of worship.

The $2 million simulation, which is aimed at students, scholars, travelers and anyone else interested in history and urban planning, can be easily updated to reflect the latest knowledge about the ancient city. In future releases, the project will include other phases in the evolution of the city, from the late Bronze Age in the 10th century B.C. to the Gothic Wars in the 6th century A.D.

VideoJug and Expert Village | “How To” Video Sites with Differing Models For Content Producers.: “

I have previously outlined 3 video sites that specialize in ‘How-To’ type educational videos. Of these 3 there are two which stand out as the 2 main competitors in this niche. These are VideoJug and ExpertVillage.

The two companies are very similar providing education how-to videos on everything you can think of from Gardening Videos to Earthquake Survival.

CDT Urges Congress to Make CRS Reports Available: “CDT Executive Director Leslie Harris today urged lawmakers to make the unclassified, taxpayer-funded reports produced by the Congressional Research Service (CRS) available to the public over the Internet. Harris joined other open-government advocates at an event on Capitol Hill to unveil the recommendations of the Open House Project, a collaborative effort launched earlier this year by the Sunlight Foundation to make the House of Representatives more readily accessible to ordinary citizens on the Web. CDT created OpenCRS.com in 2005 to increase the public availability of CRS reports and has long advocated for Congress to make the reports fully available to the public online.”
