An ontology (in the sense of computing and information science) differs from a taxonomy, in that a taxonomy organizes categories through a fixed set of (often hierarchical) semantic relations, whereas an ontology also affords the definition and meta-relation of semantic relations themselves. (this definition is bad; make a better one someday)
An ontology is a type of controlled vocabulary that formally defines, not only what kinds of thing exist in a particular domain of discourse, but how those things can relate to one another.
