A scoping review of semantic integration of health data and information

•We summarized a decade of new research focusing on semantic data integration (SDI) since 2009.•Semantic data integration approach can effectively resolve the semantic heterogeneities across different data sources.•Many of the existing SDI studies used data from only single-level data sources (e.g., integrating individual-level patient records from different hospital systems)•Documentation of the data integration processes is sparse, threatening the reproducibility of SDI studies.
