Crowdsourcing Tools and Applications

  1. 1. HABTAMU DUGO CROWDSOURCING
  2. 2. What is crowdsourcing? • Crowdsourcing is an online, distributed problem solving and production model. • Users--also known as the crowd--typically form online communities based on the website, and the crowd submits solutions to the site or produce its contents. • The crowd can also sort through the solutions, finding the best ones. • These best solutions are then owned by the entity that broadcast the problem in the first place--the crowdsourcer • The winning individuals in the crowd are sometimes rewarded. • Many individuals in the crowd participate just for intellectual stimulation or because of emotional ties to product or service
  3. 3. Definition  Crowdsourcing is the act of outsourcing tasks, traditionally performed by an employee or contractor, to an undefined, large group of people or community (a "crowd"), through an open call.  The term “crowdsourcing” was coined by journalist Jeff Howe in a 2006 Wired magazine article, which established that the concept of crowdsourcing depends essentially on the fact that because it is an open call to an undefined group of people, it gathers those who are most fit to perform tasks, solve complex problems and contribute with the most relevant and fresh ideas.  For example, the public may be invited to develop a new technology, carry out a design task (also known as community-based design[1] or "design by democracy" and distributed participatory design), refine or carry out the steps of an algorithm (see human-based computation), or help capture, systematize or analyze large amounts of data (see also citizen science).
