The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) just activated the Digital Humanitarian Network (DHN) in response to Typhoon Yolanda, which has already been described as possibly one of the strongest Category 5 storms in history. The Standby Volunteer Task Force (SBTF) was thus activated by the DHN to carry out a rapid needs & damage assessment by tagging reports posted to social media. So Ji Lucas and I at QCRI (+ Hemant & Andrew) have launched MicroMappers in partnership with the SBTF to micro-task the tagging of tweets. We need all the help we can get given the volume we’ve collected (and are continuing to collect). This is where you come in!
You don’t need any prior experience or training, nor do you need to create an account or even login to use the MicroMappers TweetClicker. If you can read and use a computer mouse, then you’re all set to be a Digital Humanitarian! Just click here to get started. Every tweet will get tagged by 3 different volunteers (to ensure quality control) and those tweets that get identical tags will be shared with our UN colleagues in the Philippines. All this and more is explained in the link above, which will give you a quick intro so you can get started right away. Our UN colleagues need these tags to better understand who needs help and what areas have been affected.
