In　order　to　understand　the　interdisciplinary　attributes　among　postgraduate　supervisors　of　Beijing　University　of　technology,　this　paper　takes　the　journal　papers　published　by　postgraduate　supervisors　as　the　research　object,　collects　the　journal　papers　of　postgraduate　supervisors　of　Beijing　University　of　technology　from　2002　to　2020　in　the　HowNet,　and　proposes　a　measurement　model　of　teachers＇　interdisciplinary　degree.　constructs　a　corpus　with　keyword　information,　and　combines　TF-IDF　algorithm　to　improve　cosine　similarity　to　explore　the　interdisciplinary　attributes　between　supervisors　and　disciplines.　The　results　show　that　the　postgraduate　supervisors　in　the　Institute　of　construction　and　engineering　have　higher　interdisciplinary　degree　than　those　in　other　colleges;　The　interdisciplinary　attributes　of　postgraduate　supervisors　are　closely　related　to　their　own　qualifications　and　experience.　　©　2022　ACM.
