术语学系统的建设需要一个合适的社会文化环境。因为（1）术语系统是个开放系统，需要容纳几乎是无穷无尽的不同意见，这些不同意见必须大多数是建设性的,认真的。而且（2）术语系统是一个永恒演化系统，它永远也不会停止更新和发展，但同时又非常尊重历史。
SNOMED CT做到了这两点。
但也许SNOMED开发较早的缘故，我觉得SNOMED的知识的理论研究相对薄弱，与其当前在医学信息学的地位不太相称。其实该文反映的下列问题我觉得就是理发师悖论和康托悖论的翻版的，原因就出在集合是可以包含其自身的（自反的）。
Reengineer the SNOMED CT
***Proper-part-of vs. part-of
*Part-of is reflexive
***Has-exact-location vs. has-location
*has-exact-location associates an event with a location in which it happens as a whole,for instance, ‘amputation of upper limb’ happens exactly to the upper limb as a whole and not just any part of it.
*has-location relates an event to any containing spatial location it occurs in, i.e., either part or whole of the specified location. For instance, ‘injury to upper limb’ happens to the upper limb as a whole or any of its parts.
