Thanks, Richard,

I'll take a look at what OntoWorld.org is doing - last time I check their
site I didn't notice any external vocabulary though.

It's also interesting how papers are different from presentations - I was
even thinking about adding papers as separate class because there is
definitely a huge set of scientific conferences that is following academic
approach and they all have submitted papers and stuff, but there is also
huge set of conferences, especially in technology, that don't do that and
only have presentations slides or videos available. I'll take a look at
DBLP, but this difference in papers/presentations might be a core problem in
connecting to it, although it might be quite useful in getting the idea of
the vocabularies and stuff.

As for - I wonder what's the primary purpose of
this? Is it human-editable interconnection tool? I think interface for such
editing is very important especially when real-life experts are used to
identify such connections (e.g. for solving disambiguation problems).

I wonder if anyone on the list came across such issues and involved experts
help (or any manual human editing) in connecting datasets and which tools
were used?
