Building accurate knowledge of the identity, the geographic distribution and the evolution of species is essential for the sustainable development of humanity, as well as for biodiversity conservation. However, the difficulty of identifying plants, animals and fungi is hindering the aggregation of new data and knowledge. Identifying and naming living organisms is almost impossible for the general public and is often difficult even for professionals and naturalists. Bridging this gap is a key step towards enabling effective biodiversity monitoring systems. The LifeCLEF campaign, presented in this paper, has been promoting and evaluating advances in this domain since 2011. The 2023 edition proposes five data-oriented challenges related to the identification and prediction of biodiversity: (i) BirdCLEF2023: bird species recognition in audio soundscapes, (ii) GeoLifeCLEF 2023: location-based prediction of species based on environmental and occurrence data, (iii) PlantCLEF 2023: image-based plant identification at global scale (300K classes), (iv) SnakeCLEF 2023: snake species identification in medically important scenarios, and (v) FungiCLEF 2023 Fungi recognition from image & metadata

CLEF Conference and working notes

CLEF Initiative CLEF 2023 logo

LifeCLEF lab is part of the Conference and Labs of the Evaluation Forum (CLEF). CLEF consists of independent peer-reviewed workshops on a broad range of challenges in the fields of multilingual and multimodal information access evaluation, and a set of benchmarking activities carried in various labs designed to test different aspects of mono and cross-language Information retrieval systems. More details can be found on the CLEF 2023 website.

Submitting a working note with the full description of the methods used in each run is mandatory. Any run that could not be reproduced thanks to its description in the working notes might be removed from the official publication of the results. Working notes are published within CEUR-WS proceedings, resulting in an assignment of an individual DOI (URN) and an indexing by many bibliography systems including DBLP. According to the CEUR-WS policies, a light review of the working notes will be conducted by LifeCLEF organizing committee to ensure quality. As an illustration, LifeCLEF 2022 working notes (task overviews and participant working notes) can be found within CLEF 2022 CEUR-WS proceedings. These proceedings are indexed by most bibliography repositories such as DBLP, Scopus, Google scholar, ResearchGate, etc.

LifeCLEF presentation at ECIR 2023

A brief overview of the whole LifeCLEF lab will be presented at ECIR 2023 conference (April 2 – April 6, 2023).
