The　standardization　of　domain　knowledge　and　knowledge　sharing　can　be　realized　easily　based　on　ontology　technology.　However,　It　takes　time　and　effort　to　build　ontology　manually.　In　the　semi-automatic　ontology　construction　based　on　ontology　learning,　the　extraction　method　of　term　relations　has　shortcomings　such　as　poor　portability　and　low　accuracy.　To　improve　the　performance　of　ontology　term　relation　extraction,　a　new　method　of　ontology　term　relation　extraction　is　proposed　in　this　paper,　and　the　experimental　results　are　provided.　©　2019　IEEE.
