Hi,
I'm trying to work with NLPReduce
(https://files.ifi.uzh.ch/ddis/oldweb/ddis/research/talking-to-the-semantic-web/nlpreduce/index.html)
That project comes with few data sets in owl.
I want to try queries with respect to "people"( questions related
to people)
Does DBpedia has any test data set in owl about people that I can
use in NLP Reduce?
Do you mean a dataset containing data about people only (no other
types).
Thanks!

Ah, yes. Exactly
Thanks
Actually there is no such dataset (dataset for a specific type), but you
can still generate it yourself, as follows:
1. Get a list of all people in DBpedia, this can be done using SPARQL
queries but with increasing the "OFFSET" in each call, as follows:
a- SELECT * WHERE { ?s a dbpedia-owl:Person } limit 1000
b- SELECT * WHERE { ?s a dbpedia-owl:Person } limit 1000 OFFSET 1000
c- SELECT * WHERE { ?s a dbpedia-owl:Person } limit 1000 OFFSET 2000
and so on.
2. Append the results returned each time to a file.
3. After finishing the last step, you should have a file with a full
list of all people in DBpedia.
4. Iterate through that file and pick a resource each time.
5. Replace the word "resource" in the URI with the word "data" and
append ".ntriples" to the end if you want the output format to be
N-Triples, e.g. for resource
"http://dbpedia.org/resource/Lionel_Messi"; you should use
"http://dbpedia.org/data/Lionel_Messi.ntriples"; to get his full data
in N-Triples.
6. Use the URI you have just created in the last step to get the data,
using "curl" Linux command or anything equivalent if you are using
another OS.
7. Append the returned triples to a file.
8. By the end of that step you should have a full dump of people only.
