PROGRESS: DDE Knowledge Editor


On September 30, 2021, the Editor product team collected requirements for the new edition of the Geoscience Knowledge Graph Collaborative Editor System. The team of Prof. Yunqiang Zhu (provided the DDE Knowledge Graph Ontology Construction Guide, made rules for the uniform resource locator, identifier naming, concepts of ontology and its attributes, relations and creating instances), and the team of Prof. Xiumian Hu all agreed that the new Editor needs to make the breakthrough in the following four aspects:

(1) Further improve the creation of concept attributes, relations and instances. Supplement sources of concept definitions, including monographs, references, network sources, existing ontologies and machine recommendations. The concept attributes are divided into data attributes (selecting different types) and object attributes (citing object classes). Complete the definitions of relations (relation types, directions and characters) and define semantic, time and space relations. Perfect the inheritance of instance to concept attributes and relations, and so on.

(2) Supplement the thoughts of the basic ontologies shared by inter-disciplines, such as the ontology of time and space, as well as the common attributes of disciplinary objects.

(3) Optimize the viewing and auditing process of different versions of ontology and improve the viewing and auditing functions, and add the real-time statistical function for contributors and the creation of geological knowledge.

(4) Collaborate with the knowledge automatic extraction system of Shanghai Jiaotong University: the intelligently assisted input of concept source literature, the audit of new ontology automatically discovered by computer, etc.

On October 10, 2021, based on the above objectives, the product team analyzed and confirmed the functions that can assist in achieving the above objectives (required by the system), completed the design of the system prototype (Figure 1). The UI team completed the UI design drawing synchronically (Figure 2).

From October 11, 2021, to December 10, 2021, the development of the main process and main functions of the system was completed and the internal test stage was entered.

From December 15, 2021, to now, the functions of the Editor system have been improved and optimized in the key stage (Figure. 3). Prof. Yunqiang Zhu and his team members, and Haipeng Li tested the system and optimized the system functions according to the test opinions. They also prepared the product training materials (user manual, operation video and concept video) and the system operation training meetings.
