Résumé

Building accurate knowledge of the identity, the geographic distribution and the evolution of living species is essential for a sustain-able development of humanity, as well as for biodiversity conservation. Unfortunately, such basic information is often only partially available for professional stakeholders, teachers, scientists and citizens, and often incomplete for ecosystems that possess the highest diversity. In this con-text, an ultimate ambition is to set up innovative information systems relying on the automated identification and understanding of living or-ganisms as a means to engage massive crowds of observers and boost the production of biodiversity and agro-biodiversity data. The LifeCLEF 2018 initiative proposes three data-oriented challenges related to this vi-sion, in the continuity of the previous editions, but with several consis-tent novelties intended to push the boundaries of the state-of-the-art in several research directions. This paper describes the methodology of the conducted evaluations as well as the synthesis of the main results and lessons learned.
