Re: MHDBDB: Connecting Senses with multiple Concepts

Hi Peter,

Yes, to summarize other authors, it is not expected that a sense should
have multiple references, unless they are semantically equivalent (e.g.,
skos:exactMatch). This seems relatively straightforward if you think
about... if you make a distinction in your SKOS thesaurus, why wouldn't the
same distinction be necessary in the lexicon? Similarly, different
parts-of-speech necessarily have different meanings, so again they should
have distinct lexical entries and senses.

The new lexicography module
<https://www.w3.org/community/ontolex/wiki/Lexicography> will provide more
modelling for group senses in order to represent the structure of existing
dictionaries and may better suit your use case.

Regards,
John
