CROWDSOURCING
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
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).

Cicada Trackers WYNC’s data team partnered with NPR RadioLab’s project dubbed “Mapping Swarmageddon.” They distributed sensors to the crowd from CT to GA to alert scientists when they saw cicadas emerge—predict their arrival.
This was a very successful CS project leading to mapping Cicadas.
Application of Crowdsourcing to Journalism
Stop and Frisk Watch App for iPhone and Android (Available in English and Spanish) The New York Civil Liberties Union launched
the app “ to empower New Yorkers to monitor police activity and hold NYP accountable for unlawful stop-and-frisk encounters and other police misconduct.”
The App has three primary functions: record, listen, and report.
NYCLU reports a success because the app was downloaded over 30,000 times.
Application of Crowdsourcing to Journalism….
Times and the Lede Blog Times took journalistic crowdsourcing to the
next level by inviting members of the crowd at the scene of the Boston Marathon bombing to verify information in frozen frames.
Times assigned editors and reporters vet the videos and themselves first by finding the people in the video and then asking the crowd to help them find the rest: “ Were you or someone you know at the Marathon
finish line?” 4 of the 19 verified accounts came from the
crowd.

The Guardian’s MP Expenses Scandals Experiment
Shoveled public record onto a simple feedback interface and enlisted more than 20,000 volunteers to help them “find needles in the haystack.”
170, 000 documents reviewed in the first 80 hours.
This large scale crowdsourcing cost The Guardian only £ 50 to rent temporary severs.
This job was impossible to do with the labor and skills of their own few journalists
CS Application to Journalism Cont’d
Good journalistic crowdsourcing takes into consideration the validity, quality, and ownership of the data journalists are accessing. When used effectively, it is a unique way to engage audiences and gather information that paints a more comprehensive picture of what’s going on in the world.
Crowdsourced journalism showed its limits during the Boston bombing
It was an iPhone photo that provided the clearest image of one of the suspects.
Yet Boston also showed the drawbacks to relying on crowdsourced information without verification: innocent men were falsely identified as suspects in the days after the bombing.
Good Journalistic Crowdsourcing
1. Your workers are unpaid, so make it fun2. Public attention is fickle, so launch
immediately 3. Speed is mandatory, so use a framework4. Participation will come in big burst, so
have servers ready. 5. Reward participants (recognition or
financial compensation for the person who comes up with the best solution)
6. What do you think?
