DDE Knowledge is dedicated to data-driven discovery. It is a tool to create knowledge, especially for geoscientists. A standard knowledge graph is being developed for deep-time Earth data and will serve as a knowledge service platform for scientists, the public, and governments. As an approach to collaboratively creating knowledge, standard intelligence tools have been designed and are open to the public. New features and models are being integrated into the DDE knowledge graph and detailed technical implementation framework to express complex geological entities and relationships between them has been designed through the joint efforts of geoscientists and data scientists.
