Within a single defined terminology the mapping should be one-to-one.
With NL it is many-to-many. (06)
[LEO:] Alas, I've seen many terminologies, controlled vocabularies where it is
not that simple. Would that it were! I agree we should aspire to this. (07)
When using multiple defined terminologies, the mapping would be many-to-one
for concepts that are represented in multiple ontologies. When using
ontologies, if the full name of an ontological term includes a unique
reference to the ontology, then the issue of many-to-many would not
arise. If one carelessly uses terms from multiple ontologies without
designating which ontology the term comes from, one is back to
many-to-many. (08)
[LEO:] I am guessing that you mean something like a namespace prefix for the
term, right? If you enforce a unique reference from a term in the
terminology/vocabulary to a concept in an ontology, of course you do get
uniqueness. The problem comes in when a given terminology has ambiguity, and
well it might if it reflects the usage of its users. Term: tank, Concept: tank.
Many terms, many concepts. Admittedly these are different word-senses in
linguistics, and so the lexicon does map from wordsense 1 (your namespace) to
concept(s) 1, wordsense 2 to concept(s) 2, etc. The term "now" in a real sense
can be defined very strictly, though the reference (instances) in the real
world will vary, as it will in the linguistic discourse/utterance. One must
define "now" semantically and ontologically, if you want to have a mapping so
that your terms "now" can pick out the right "now" referents. (09)
A term in an ontology can designate a word in a natural language --
one just need distinguish between the ontological term and the word
designated. The ontology can then define referents and forms of the
word. E.g., in Cyc:
inMt: EnglishLanguageMt.
(isa Bank-TheWord EnglishWord)
(singular Bank-TheWord "bank")
(infinitive Bank-TheWord "bank")
(denotation Bank-TheWord CommonNoun 1 BankOrganization)
(denotation Bank-TheWord CommonNoun 2 BankBuilding) ...
(denotation Bank-TheWord CommonNoun 4 Bank_Topographical)
(denotation Bank-TheWord Verb 1 Banking) ...
Cyc has default rules for determining plurals, conjugations, and tensed
versions of words -- along with ways of specifying irregular forms so
that the default rules would not be triggered when inappropriate. Also
note that this is contextual, so that in the context of another language,
the text string "bank" would be the orthography for a different word,
and that word's denotations need not have any relation with the English
denotations for Bank-TheWord. (010)
[LEO:] Yes, you can put lexicons (and so, terms) into the ontology ala Cyc
here, but that typically is not the case. Usually one considers a lexicon, the
semantics of that lexicon (or its composition for composition of terms), and
the ontology as distinct. Even in Cyc, I think the attempt is to clearly
distinguish these. (011)
