Biodiversity4all Research-Grade Observations

BioDiversity4All

Description

Observations from BioDiversity4All, an online social network of people sharing biodiversity information to help each other learn about nature. BioDiversity4All is maintained by Associação Biodiversidade Para Todos, and the Portuguese node of iNaturalist, a joint initiative of the California Academy of Sciences and the National Geographic Society.

Quality control

BioDiversity4All as an iNaturalist node follows the same methodology. iNaturalist observations become candidates for Research Grade when they have a photo, date, and coordinates. They become Research Grade when the community agrees on an identification. If the community has multiple opinions on what taxon has been observed, iNaturalist chooses a taxon from all the proposed taxa (an implied ancestor taxa of the proposed taxa) that more than 2/3 of the voters agree with. The full algorithm is as follows: for all identified taxa and the taxa that contain them (e.g. genus Homo contains Homo sapiens), score each as the ratio between the number of cumulative IDs for that taxon over the sum of the cumulative IDs, the number of more conservative IDs added after the first ID of that taxon, and the number of IDs that are completely different (i.e. IDs of taxa that do not contain the taxon being scored). For the identified taxa that have a score over 2/3 and at least 2 identifications, iNaturalist chooses the lowest ranked taxon as the community taxon. An observation can lose Research Grade status if the community has voted it down on several metrics, including whether the organism is wild / naturalized (i.e. not captive / cultivated), whether the location and date seem accurate, and whether the content of the observation is appropriate for the context (e.g. violation of iNaturalist's Terms of Service, copyright violation, plagiarism, etc.).
