Thank you Mohamed.
Exactly what I needed.
Is there any in built limitation? I used:
SPARQL: SELECT ?s WHERE {?s a <http://schema.org/Person>}
and I got a suspectly low and round number of 50,000 :) . For example
Abraham_Lincoln is not in the CSV file I downloaded.
Also, is there any 'magic' statement to get the short abstracts from
'short_abstracts_en.nq' for the 'categories' selected in 'instance_types_en.nt'
be it 'Book', 'Place', etc.?
Cheers,
M

You can either use UNIX commands or SPARQL queries against one of
the SPARQL endpoints [1, 2], to get the information you are looking
for.
* UNIX: grep '<http://schema.org/Book>' instance_types_en.nt > output.nt
where output.nt is the output file.
* SPARQL: SELECT ?s WHERE {?s a <http://schema.org/Book>} limit 1000
