<title>什麼叫Ontology?</title>
<link>http://blog.roodo.com/myroodo/archives/2817405.html/</link>
<description><![CDATA[根據wikipedia的解釋: In philosophy, ontology is the study of being or existence. It seeks to describe or posit the basic categories and relationships of being or existence to define entities and types of entities within its framework. Ontology can be said to study conceptions of reality.In computer or information sciences, ontology is a data model that represents a set of concepts within a domain and the relationships between those concepts. It is used to reason about the objects within that domain.在哲學術語上，Ontology指的是一種探討&quot;存在&quot;的一門學問，也就是萬物存在這個宇宙，到底是安命在何處，以及萬物之間的關係為何。所以Ontology又稱之為&quot;存在學&quot;或&quot;本體論&quot;。用白話來說，就是各種活的、死的東西，到底他是屬於哪個類別，可以歸類在何處，並且這些活的、死的東西之間到底有什麼關係。 ]]>
