|Abstract: ||In traditional computation, a human employs a computer to solve a problem; a human provides a formalized problem description to a computer, and receives a solution to interpret. Human-based computation frequently reverses the roles; the computer asks a person or a large group of people to solve a problem, then collects, interprets, and integrates their solutions. Human-based computation is a computer science technique in which a computational process performs its function by outsourcing certain steps to humans. This approach leverages differences in abilities and alternative costs between humans and computer agents to achieve symbiotic human-computer interaction.
Tasks like image recognition are trivial for humans, but continue to challenge even the most sophisticated computer programs. Human computing introduces a paradigm for utilizing human processing power to solve problems that computers cannot yet solve. Traditional approaches to solving such problems focus on improving software. A novel approach is constructively channel human brainpower using computer games. For example, the ESP Game. Another example is CAPTCHAs. An automated tests that humans can pass but computer programs cannot. CAPTCHAs take advantage of human processing power in order to differentiate humans from computers,
an ability that has important applications in practice.
Practical applications of this work include improvements in problems such as: image search, adult-content filtering, spam, commonsense reasoning, computer vision, accessibility, and security in general.|
