Hi Alexandre,

In the field of Linked Data we cannot only talk of ontology matching or
instance matching as separate fields, in my opinion its something in the
middle, as you mostly have to check predicates, properties and class but
also match the instance values if you need to interlinking resources.

I'm talking of using instance information and matching distances to create
owl:sameAs interlinking. For example,  geo:lat, geo:long can be used in
order to match (e.g. using haversine distance) with other geolocated
instances, or string matching measures like Jaro-Winkler could be applied
for rdfs:label or any other string label.


Some useful references:

Hope this helps
