About 🌏🌍🌎

Project status: Pre-release. Alpha Knowledge graph ETA end of Q4 2025. (Updated Sept. ’25)

The Climate Knowledge Graph (CKG) is an R&D project to make a knowledge graph of the open access parts of the 10,000 page IPCC Sixth Assessment Report (AR6) corpus.

Git repo: CKG

Goal 🥨

The goal is to enable easier knowledge use from complex document corpus by:

  1. Making corpus search results available as multi-format publications, and
  2. enabling corpus data analysis by providing FAIR linked open data resources.

CKG uses open-source software and can be used on any document corpus.
