A short
statement situating your perspective of interest w.r.t. to
the CEDAR projectÕs theme:
One of my research interests is data exchange for heterogeneous data formats, among
which RDF-shaped
data. While data exchange and ontology reasoning are somehow complementary, they can be also unified under a common
perspective, i.e. generating additional knowledge in a target
database.
Your
positive thoughts (if any);
My overall impression is that there
has been a huge amount of work in this project.
I think
that some ideas such as binary
encoding for ontology reasoning (first track of the
Cedar project) and the efficiency
of the in-house hadoop
triple-store
(second
track of the Cedar project)
need to be further explored in future research, and also better highlighted
in the community.
Your criticisms (if any);
Honestly, what I am reporting here is not a criticism,
but it has
to be seen as a mere
suggestion: I would try to see whether
individual results (such as the binary
encoding for instance) can
be applied to other
contexts and can be thus seen as a contribution
on their own.
Your overall opinion of the project
from your perspective.
I believe
that the project has arisen very
important research questions (in such a little timeframe) and shown that in practice
things may
be more efficient than expected if we
only are able to implement them from scratch, to tweak them and thus to fully understand
them.
As a researcher, I really appreciate that, and I also must hope that this
is not the end, it is not
even the beginning of the
end but it is perhaps
the end of the beginning
(the last statement is drawn from W. Churchill).
Best regards,
Angela
