Abstract: Highlights•A domain ontology HSO is built to formalise domain knowledge about hydraulic systems.•A virtual knowledge graph system is explored to facilitate data integration.•An intelligent predictive maintenance approach is proposed to predict degradation.•The effectiveness of the proposed approach is evaluated on a real-world case study.
