Re: MHDBDB: Connecting Senses with multiple Concepts

Dear Peter,

great to see the MHDBDB being converted to RDF. For your use case, I would  
actually not model the conceptual system itself in lemon, but rather use  
SKOS and provide only lexicalization information in lemon. In other words,  
your concept hierarchy is the ONtology element in lemON and ONtoLex, and  
this is actually the original use case of lemon.

The relation for linking with an ontology is ontolex:reference. The spec  
requires that "The lexical sense has a single lexical entry and a single  
reference in the ontology." (As in other cases, I think this is too  
restrictive.) So, your problem remains the same.

The "proper" solution would be to create "lexicalized concepts" in your  
thesaurus (which can have skos:broader relations to more than one skos  
concept), and to connect these with your lexical entries via  
ontolex:reference.

A shortcut, if you will, would be to use blank nodes as part of the  
ontolex linking:

mhdbdbLex:sense4709 ontolex:reference [ skos:broader  
mhdbdbThes:concept23250000,  mhdbdbThes:concept23309000,   
mhdbdbThes:concept23309020 ] .

Technically, this would be valid, but it is a bit borderline, because the  
blank node is not strictly speaking *in* the ontology/thesaurus. (It is  
certainly not worse than not having an ontology, though, as in most  
lexicography use cases.)

 From a modelling perspective, I would prefer the second solution despite  
these difficulties, as otherwise, the thesaurus grows infinitely with  
every novel word being added. Blank nodes created as part of the linking  
are easy to filter out if you need to work with the categories alone.  
Also, imagine a use case where you have different lexicalizations/lemon  
models to be linked to a single ontology, and those lemon models may  
require fusing concepts in a different way. Using blank nodes as part of  
the linking makes sure that lexicalization- (lexicon-) specific concept  
fusion can be clearly separated from the (language-independent) concept  
hierarchy.

We have similar difficulties (and no better solution) for multiple parts  
of speech for the same lexical entry, etc.

Best,
Christian
