I'd say that things are represented well in Dbpedia when the things are
objects that have well defined properties.
For instance, if I show up at the courthouse with a birth certificate that
documents my date and place of birth and my parents, that proves that I'm a
particular Person.
One of the goals of the infovore project is to develop something that
targets this latency problem.

I’ve talked with a number of organizations that use DBpedia and Freebase
data and almost all of them have either no solution or an incomplete
Any chance we can get a well-defined interface that could be used to run
‘rdfslice’ as an Infovore application but still let people run it independently
of Hadoop? I think that would help with the “number of hours” problems.

My feelings are strong towards one-line-per-fact.
Large RDF data sets have validity problems, and the difficulty of
convincing publishers that this matters indicates that this situation will
continue.
I’ve thought a bit about the problem of the “streaming converter from

Thanks Paul. The end goal of this data is import into AWS SimpleDB and

I can report my progress on this front.
I’ve got a system in place that moves Freebase dumps, recompresses them and
stores them in the AMZN cloud. I can suck in DBpedia data the same way.
I’m hadoopifying my Infovore tools so I can do my preprocessing, parallel

I am a fan of the SPARQL result set format whenever people want to express
tuples of nodes:

I think it’s more standard than Turtle, and it is as efficient as you’ll get
unless you want a binary format.

PRESS RELEASE
Paul Houle, Ontology2 founder, stated that we updated Infovore to accept
data from DBpedia, and ran a head to head test, in terms of RDF validity,
between Freebase and DBpedia Live.
Unlike most scientific results, he said, these results are repeatable,
because you can

We've cracked the code of the Freebase quad dump and produced

industry-standard RDF.
