SPARQL Query Generation
Hello All !
I am working on a Semantic Web Project where the user enters text query
like "US president " and I have to generate automatic sparql query based on
user's input text to retrieve results from TDB triple store.
I am confused how to select subject, predicate and object.
Though translating natural language into SPARQL queries is not an easy task
.
Are there any helpful tools in Jena to generate sparql query from English
query.
Example:
SQUALL sentence:
How many person-s are an author of PaperX?
SPARQL translation:
SELECT DISTINCT (COUNT(DISTINCT ?x2) AS ?x1) WHERE {
?x2 a :person .
:PaperX :author ?x2 .
}
Thanks in advance.
Regards,
Amal

Amal,
That is a very interesting research question. We have given it some initial thoughts but far from any practical solution. Please keep us posted on your progress and let us know if you have any published work on that topic either your own or from other authors.

Hi Amal et al,
The links and online system below are about generating SQL, not SPARQL, but
may be useful background.

good morning;
from the back of my mind, “aksw” popped up and, in fact, they have at least one link to their work in this area:
aksw.org/Projects/AutoSPARQL
it was the top link in a google search, but google claims there appear to be numerous others.
best regards, from berlin,
