Hi Abhijit,
Understanding of graph structured data, specifically RDF syntax and
SPARQL, is a mandatory requirement for working with us.
I suggest you to first read the Wikipedia article about RDF [1], then to
dig into the official specs [2, 3, 4].
Cheers!

The exception occurs because ImageExtractor needs the commons dump, but you
didn't download it. The following should be in your download.properties:
# Only needed for the ImageExtractor
download=commons:pages-articles.xml.bz2
(Copied from download.1.properties.)
Just run the download again,
Hi Mariano, everybody,
I went through the code and it looks good. The project is very exciting and
I hope I can join you during this summer!
Apart of running the extractor and browsing the code, I read this reference
[1] and it is one of the most informative sources about dbpedia.
Congratulations
Hi João,
I'll try to answer your questions:
(1) I don't know exactly what happened since I only run the live extraction
for German, but I assume there was some sort of downtime or error that
prevented the update of one of the resources. We'd need to inspect the
SPARUL update stream of the dbpedia
Hi Marco,
Thanks for your email. I went through all the links that you provided. I am
beginning to find the semantic web concept quite fascinating.
I am making progress with the SPARQL tutorial, and I have noticed that as
long as I have sufficient knowledge about the dataset, writing queries is
no
I am not a field expert but the complexity of the automated sparql queries
should not be big.
Maybe the queries will become big with many triple patterns but not too
complex.
Here you can get an overview of some query types you *might* encounter:
