Privacy　protection　is　a　hot　topic　in　network　security.　Many　scholars　are　committed　to　evaluating　privacy　information　disclosure　by　quantifying　privacy,　thereby　protecting　privacy　and　preventing　telecommunications　fraud.　However,　in　the　process　of　quantitative　privacy,　few　people　consider　the　reasoning　relationship　between　privacy　information,　which　leads　to　the　underestimation　of　privacy　disclosure　and　privacy　disclosure　caused　by　malicious　reasoning.　This　paper　completes　an　experiment　on　privacy　information　disclosure　in　the　real　world　based　on　WordNet　ontology.　According　to　a　privacy　measurement　algorithm,　this　experiment　calculates　the　privacy　disclosure　of　public　figures　in　different　fields　and　conducts　horizontal　and　vertical　analysis　to　obtain　different　privacy　disclosure　characteristics.　The　experiment　not　only　shows　the　situation　of　privacy　disclosure,　but　also　gives　suggestions　and　method　to　reduce　privacy　disclosure.
