Hi,
I think we all want to do the same thing: aligning vocabularies in order
to enhance interoperability in the cloud. There is the top-down
approach: aligning vocabularies first, and using the alignment to
provide functionalities for the data. For example, if Google releases a
dataset using their googlevocab ontology, we could use an alignment
between it and FOAF to tell a link generator under which classes similar
instances will be found. (advertisement: providing alignments is the
task of the alignment server [1]).
With this experiment we want to go in the other direction, from data to
vocabularies. We take this path by looking at link generator
specifications, what they need as input, and see in what degree it would
be possible to abstract this input as a kind of ontology alignment. This
could provide functionalities such as aggregation, composition and
verification of links and alignment (see detailed description [2]).
Cheers
François

Hi,
To put it in simple terms for me :-)
Are you after the algorithms we use to identify when two instances are
the same?
No, he isn't talking ABox. He is talking TBox (data dictionary).
I posted a link about a simple mapper ontology for Google's RDF vocabs
that basically prevent the innocent from using those terms
and ending up down a swamp (to put things as mildly as possible).
See: http://purl.org/NET/googlevocab#
UMBEL is about doing this on bigger and broader scales :-) That's always
been the purpose of this project since inception.

Dear LODers,
There has been a couple of discussions already on this list on the need
for a vocabulary to represent correspondences between terms of different
vocabularies. We also saw recently various tools (e.g. Silk, ODDlinker)
allowing to automatically interlink datasets given a specification of
what should be linked.
However, there is currently no common way to publish and share this
information (i.e., not the links but the way to generate them, see [1]
for precision).
We are setting up an experiment [1] to see if it is possible to provide
useful services from this data. But for that purpose we need your help.
So this is a call for contribution: we are collecting any specification
of link generator for the LOD graph.
Of course, do not hesitate to comment on the idea or to tell us if you
want to be involved.
We promise a report on this by the end of summer (northern hemisphere :).
Cheers,
François
