Interesting, thanks for the reference. I was aware that there's has
been and continues to be a lot of research in this area, but was just
wondering out loud whether anyone has explored opening up some kind of
matching service on a more production footing, either as an automated
service or using crowd-sourced mappings.

Running tools locally, and explore their effectiveness would he an
interesting exercise. But presumably  there will be a need to start
surfacing some services in this area soon, as part of the general
semweb infrastructure.

Cheers,

L.
