EXPLORATOR is a citizen science project of the Herbarium of the University of Coimbra to digitise the largest portuguese biological collection. It is a crowdsourcing platform to transcribe information of herbarium specimens.
In EXPLORATOR, is suggested to the user an image and a form to write the relevant data, one field at a time, which makes it easy to progress throughout the session. Each field has a help icon to answer the most common questions. When a value is submitted, the platform verifies if different values have been submitted for that field, which helps to avoid errors by mistake or distraction, but can also help less experienced users to better understand the type of information requested. In order to allow users to become familiar with the herbarium specimens and the type of information it contains, only easy identification fields are required at an early stage. As users respond, their responses are validated. The number of responses considered correct allows the user to level up, with more complex fields being requested.
