The document discusses open science and how citizen science can help address existential threats like climate change and antibiotic resistance. It presents the OpenNotebook approach, which involves reading millions of open access articles and extracting information using XML tools. The slides demonstrate downloading articles from EuropePMC, transforming the JATS XML to HTML, searching the texts using dictionaries, and visualizing the results. The goal is to make scientific literature universally available and support open, collaborative science by citizens worldwide.
