Illuminating BHL’s Dark Data: Citizen Scientists and AI Unlock Key Biodiversity Data in GBIF

Technical staff from BHL are working to establish a scalable data pipeline of occurrence data currently trapped in archival field notes, journals, letters, correspondence, and other primary source materials housed in BHL. Thanks to a pilot project with researchers from Harvard University and volunteer transcription projects hosted via DigiVol, BHL was able to make its first deposit of occurrence data into the Global Biodiversity Information Facility (GBIF). This deposit of historic biodiversity data demonstrates how valuable BHL’s collection is to global biodata infrastructure, as it plays a crucial role in establishing species base lines, informing climate change studies, tracking key environmental indicators, and contributing to the development of global biodiversity monitoring platforms.

Unifying Biodiversity Knowledge to Support Life on a Sustainable Planet by Jacqueline J. Dearborn

Interlinking BHL Data in the Wikimedia Project Ecosystem

The planet is at a critical juncture, where urgent action is required to combat climate change and biodiversity loss. With the release of the recent BHL Wikimedia white paper entitled Unifying Biodiversity Knowledge to Support Life on a Sustainable Planet, BHL hopes that an expanded data vision for the BHL community presents new opportunities with Wikimedia projects and the emergent semantic web. The white paper sheds light on BHL’s crucial role as a member of the biodiversity informatics community and reveals a series of key use cases and big data challenges that, if addressed, could be opportunities to enhance global biodiversity data infrastructure.
