About

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

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.
