BirdCLEF 2018 ImageCLEF / LifeCLEF - Multimedia Retrieval in CLEF

As in 2017, two scenarios will be evaluated, (i) the identification of a particular bird specimen in a recording of it, and (ii), the recognition of all specimens singing in a long sequence (up to one hour) of raw soundscapes that can contain tens of birds singing simultaneously. The first scenario is aimed at developing new interactive identification tools, to help user and expert who is today equipped with a directional microphone and spend too much time observing and listening the birds to assess their population on the field. The soundscapes, on the other side, correspond to a passive monitoring scenario in which any multi-directional audio recording device could be used without or with very light user's involvement, and thus efficient biodiversity assessment. The goal of the task is to identify the species of the most audible bird (i.e. the one that was intended to be recorded) in each of the provided test recordings. Therefore, the evaluated systems have to return a ranked list of possible species for each of the 12,347 test recordings.
