This service consists of a toolkit that allows citizen science platforms (or other research projects) to develop automatic identification tools adapted to their needs, e.g. for particular groups of species. The identification tool, based on machine learning, will include a search to find similar results. For instance, among photographs of species that potentially resemble the observation made by the citizen scientist. Example: A museum developing an app related to a particular group of species will be able to integrate a photo-identification tool for that species without much effort. Service developed by Inria in the Cos4Cloud framework. Infographic's designer: Lucas Wainer. More information: https://cos4cloud-eosc.eu/services/ai-taxonomist
