Abstract: [Purpose/Significance] This paper is intend to find out the subjects structure and research progress in the field of linked data by investigating the relevant research literature.[Method/Process] Several research methods were used to analyze the linked data research in Web of Science, such as bibliometric method and visualization method. We used Citespace as visualization tool to find out who is researching on linked data. Based on the life cycle of linked data, the subject structure and research progress of linked data are explored.[Result/Conclusion] The results show that Europe is the main area for linked data researching, and Tim Berners-Lee et al. have a deep influence in the field. At present, the research of linked data covers all aspects of its life cycle include generate and publish, optimization, evaluation and application. Meanwhile there are also some weak points, such as further research on promoting the publish of linked data with high quality, realizing automatic enrichment and linking of entities, and constructing comprehensive quality evaluation.
