The knowledge-based application of geological data is a prerequisite for the intelligent application of geological data.Discusses the practical methods of multiple links in the process of knowledge conversion of geological data.Firstly,the classification of knowledge graph and semantic fusion of knowledge graph are discussed,and the classification of “subject graph” and “application graph” and the fusion idea based on OWL semantic expansion are proposed.Secondly,combined with the development of knowledge technology and the multimodal characteristics of geological data,the knowledge conversion of geological data is divided into four levels based on keywords,metadata,full text and multimodality from shallow to deep.Finally,the evaluation method of knowledge graph quality is discussed,and a idea is proposed to evaluate the quality of the graph in terms of coverage index and consistency index.Involves knowledge representation,classification,fusion,hierarchical division and quality evaluation of knowledge conversion,which is of reference significance for the systematic development of geological data conversion work.
