Re: SUO: SUMO questions
Erik,
Many thanks for addressing a substantive technical issue. I see that Ian
has responded but I'll add my two cents.
There are three WordNet synsets for the English word "department"
1. A specialized division of a large organization; "you'll find it in the
hardware department"; "she got a job in the historical section of the
Treasury".
* SUMO Equivalents: subOrganizations
2. The territorial and administrative division of some countries (such as
France).
* SUMO Equivalents: GeopoliticalArea
3. A specialized sphere of knowledge; "baking is not my department"; "his
work established a new department of literature".
* SUMO Equivalents: Proposition
Each sense maps to a different SUMO concept. So, you are quite right that
in sense #1 a department has a chair, a location and so forth. However,
the SUMO term Proposition is mapped to a different sense of "department",
which is the sense that means "sphere of knowledge". I'm a little unclear
on sense #3 in that the first sentence makes me think that it is just an
abstract Proposition, which the second sentence in sense #3 leads me to
believe that the mapping should be to FieldOfStudy.
One could argue about a noun being mapped to a Relation. This is a case
where the mapping isn't exact because it should really be to a "template"
logical expressions that addresses the logical meaning of the word in the
context of a sentence. For example
"Bill is in the hardware department." might be translated to something like
(exists (?P ?D ?O)
(and
(instance ?P Male)
(name "Bill" ?P)
(location ?P ?D)
(instance ?O Organization)
(subOrganization ?D ?O)))
A revised and expanded version of the SUMO-WordNet mappings might have as
the entry for synset #1
(exists (?D ?O)
(and
(instance ?O Organization)
(subOrganization ?D ?O)))
which would express a fragment of logic that would need to be included in a
translation to logic of the word sense used in context.
One might map to Organization instead of the relation subOrganization
though.
I hope this clarifies things somewhat.
