A reasoning and query method of equipment PHM ontology based on jena

Abstract

With the continuous development of computer retrieval technology, people have more and more demand for information semantic retrieval, and the ontology reasoning and query method based on Jena can be researched to solve this problem effectively. Through the research of ontology theory, the ontology technology is applied to the field of equipment maintenance support, and the equipment PHM ontology is built and persisted into the database. The ontology reasoning rules of PHM ontology are defined, and the ontology is deduced by using Jena inference engine. The query of PHM ontology is realized by using SPARQL query language, and it lays the foundation for the next step to study the information system of equipment maintenance support based on ontology.
