Ontology 가 뭡니까?

사전에보면, 존재론, 본체론... 뭐 이렇게들 얘기나오는데 "'''본질적 의미, 개념에 대한 명세'''" 정도로 쉽게 해석할 수 있지 않을까 싶습니다. 어떤 사물이나 현상이 있다고 할때, 그걸 표현하는 언어가 있겠고, 그 언어를 통해 바라보는 본질의 의미...

그래서, Gene ontology는 각종 유전자,분자생물학관련된 용어를 단지 사전적해석보다는 본질적 의미론적인 접근을 하고자 하는것이고, http://biohackers.net/wiki/HybridTheCreativeOntology 의 페이지제목은 Hybrid란 용어를 좀더 본질적 의미라는 뜻으로 쓰고자 함입니다.
