Science Behind The News: Crowdsourcing

The video discusses the limitations of computers compared to humans in tasks like image recognition and language translation. It introduces Luis Von Ahn, a pioneer in crowdsourcing, and his projects like CAPTCHA, reCAPTCHA, and Duolingo. CAPTCHA helps differentiate humans from computers, while reCAPTCHA aids in book digitization. Duolingo uses crowdsourcing to translate the web by engaging language learners. The video also highlights the use of crowdsourcing in scientific research, such as protein folding, demonstrating its potential to solve complex problems.

What is the primary advantage humans have over computers according to the video?

• Humans can read and interpret distorted text.

• Humans can solve complex mathematical equations.

• Humans can process data faster.

• Humans can store more information.

What was the main purpose of creating CAPTCHA?

• To increase internet speed.

• To enhance online gaming experiences.

• To filter out spam on the internet.

• To improve computer graphics.

How does reCAPTCHA contribute to book digitization?

• By scanning books directly.

• By using human input to recognize unscannable words.

• By storing books in a digital library.

• By translating books into multiple languages.

What dual purpose does Duolingo serve?

• Providing language courses and offering travel guides.

• Teaching languages and translating Wikipedia.

• Teaching languages and offering online shopping.

• Providing language courses and social networking.

What significant achievement was made by Fold It players?

• They designed a new video game.

• They created a new language translation tool.

• They mapped a protein structure in 10 days.
