Guido, all, I appreciate your comments. Before continuing to discuss the ontological status of a sense, let me provide some working definitions for "Sense" and "representedBy". Sense: meaning of a word w when intrepreted as referring to ontological concept c. And yes, we represent the connection between w and c through sense as a reification. representedBy: this captures the relation between a sense s and some symbol c (constant). The semantics of "representedBy" is something like: s is representedBy c <-> the axiomatization in c captures the ontological commitment of s This means that we assume that there is some ontological commitment in words and that this ontological commitment can be axiomatized (or not) in some ontology. This still allows to be less or more vague. If we do not add any axioms constraining the interpretation of a symbol, then we are maximally vague. So, if we take the word "bald", there is sure some ontological commitment in this word. For instance, Bruce Willis (see attached picture) is clearly bald, while Slash (the guitarist of Guns N' Roses) is not (see picture). So there is some clear ontological committment of the word "bald", though in other cases it might not be that clear-cut. Hope this makes sense and helps to clarify the notions.
