Abstract: With the development of geoscience and its related technology, geoscience data grow rapidly and a large amount have been accumulated in the recent years. To establish domain knowledge graph to promote the utilization of those data becomes an urgent task. This paper, serving a geoscientific international project, Deep-time Digital Earth, proposes a geoscience knowledge base as well as knowledge graph to provide a new tool for future geoscience research and further, promote the research paradigm. Development history of knowledge graph has been reviewed and main knowledge system editing tools have been fully evaluated. Based on the characteristics of geoscience, authors analyzed the requirements of geoscience knowledge system editing, and constructed a professional editing platform for the system. The platform owns the advantages such as simple operation and collaborative applications for review and editing, which not only meets the requirements of geoscience knowledge system but also fills a gap in this field. Since it formally launched last year, scientific researchers from 18 subjects of geoscience have participated in the online editing, and the geoscience knowledge system is progressing with this great effort and efficiency. Based on experiences from the system users and constructers, authors suggested the further improving plans for the platform from a
technical perspective.
