Human-based computation game
A game witha purpose (or GWAP) is a game played on a computer that serves some purpose for the people setting up the game by harnessing human abilities in an entertaining setting.
There are many activities that are almost trivial for humans to perform that have stymied computers. These tasks can include labelling images to improve web searching, transcription of ancient text (where OCR software faces a script they are not optimized for and degraded or damaged images) and asny activity requiring common sense or human experience.
The first example was the ESP Game, which labels images. To make it an entertaining effort for humans two players attempt to assign the same labels to an image. The game establisher records the results of matches as image labels and the players enjoy the encounter because of the competitive and timed nature of it. To ensure that the humans do there best to accurately label the images, the game requires two people (chosen at random and unknown to each other), who have only the image in common, to choose the same word as an image label. This discourages vandalism because it would be self defeating as a strategy.
