OSDG is a citizen science initiative that aims to bring together the knowledge and expertise of people from around the world to better understand the nature of Sustainable Development Goals (SDGs). The Community volunteers use the Platform to participate in labelling exercises where they validate each text's relevance to SDGs based on their background knowledge. In each exercise, the volunteer is shown a short text snippet together with an SDG label associated with it. Your task is to either ACCEPT or REJECT the suggested label! Over 1 700 citizen scientists from two thirds of the world have already contributed to a user-friendly text labeling exercise. Thanks to you, we are on track to create a large, accurate source of textual information on the UN Sustainable Development Goals (SDGs). Join us today!
