Crowd-sourcing is a technique for information gathering and discovery that has really evolved as Internet connectivity has increased. Sites like Wikipedia rely on it to provide the information others look for, but just because it is being used by many, does not mean it is being used as well as it could be.
Researchers at Tel Aviv University have developed software to optimize the information gathered from crowd-sourcing. When information is posted on a site, someone on the site’s staff have to check it to make sure the information is valid and not offensive. This task can become extremely difficult and tedious as more information comes in. The software has the ability to recognize which sources provide the best information and which are lacking. When the information is lacking, questionable, or inappropriate, the appropriate moderator can be automatically alerted to check it or improve it.
