technology. They give the
same answer on the Madonna question.
Without knowing the details I find a text file with mapping here:
The PPP SPARQL tool is great fun indeed. For example,
it does an
excellent job at
"Who is married to Madonna?"
Quite appropriately, the following question keeps "Loading ..." forever:
"What is the greatest number?"
However, I guess it's still a bug ;-)
Will this tool support qualifiers? How?
Also, where does the tool currently take its background knowledge from?
For example, how does it know that "married" is a symmetric relation?

This is awesome! Need more SPARQL tools. I guess the direction to
develop this would be to have GUI that allows to build queries
(something like we see at
https://wdq.wmflabs.org/wdq/) and maybe
making
ppp-sparql resolved queries - e.g. with actual Q-item for "president"
when I ask for "who is the president of the USA?" - which will be more
efficient.
Should we start some page where we list such tools?
Yes please.
I requested a toolinfo.json to be added to ppp-sparql:
https://github.com/ProjetPP/PPP-Wikidata-SPARQL/pull/1
Then you would just search for "sparql" here
<https://tools.wmflabs.org/hay/directory/#/search/sparql>.
I was quite surprised by how well ppp-sparql performs based on very
limited information (it's guesses on simple sentences often yield
results). Nice work! Maybe it could be more efficient to do some API
requests to find the right entities rather than filtering many
alternative labels as part of the query. It's not a pattern that we
should encourage for production ;-)

Markus
