获取.owl文件的所有类的问题

Question

我正在尝试在文本文件中写入.owl文件的所有类。但是我也收到很多不必要的东西。

我想摆脱诸如：untitled-ontology之类的术语。

untitled-ontology-17.Radiometry keep only Radiometry

And get rid of entire term such as OPB.OPB.somenumber

以下是我的代码：

onto=get_ontology("file:///Users/adarshkumar/Downloads/ontology.owl").load()
with onto:
    l=list(onto.classes())
    with open('entities.txt', 'w') as f:
            for i in l:
                if isinstance(i, ThingClass):
                    f.write("%s\n"%i)

这是我得到的输出的一部分（由于大小限制，大部分已经兴高采烈了：]

untitled-ontology-17.Radiometry
untitled-ontology-17.Astrophysics
untitled-ontology-17.Astronomical_Instruments
ontology.Bar_Magnet
ontology.Magnetic_Field_Sources
untitled-ontology-17.Magnetic_Field
ontology.Charge_Carriers
OPB.OPB_01476
ontology.Cyclotron
ontology.Electric_Motor
ontology.Galvanometer
untitled-ontology-17.Moving_Coil_Meters
ontology.Generator

OPB.Young's_Modulus
untitled-ontology-17.ACS
untitled-ontology-17.Imaging_Systems
untitled-ontology-17.AC_Circuits
untitled-ontology-17.Electric_Circuits

我为什么得到那个17.classname？为什么17？

如何获得诸如“放射线学，天体物理学等”之类的简单术语？

非常感谢您的帮助。

尝试一下：

onto=get_ontology("file:///Users/adarshkumar/Downloads/ontology.owl").load()
with onto:
    l=list(onto.classes())
    with open('entities.txt', 'w') as f:
            for i in l:
                blacklist = ["Radiometry", "Astrophysics"]
                for itm in blacklist:
                    if itm in str(i):
                        continue
                if isinstance(i, ThingClass):
                    f.write("%s\n"%i)
