OR statement in SPARQL [ask for suggestions]

[Dhira P. Yuga]

I want to select ?hasTitle and ?hasKeyword where ?hasTitle OR ?hasKeyword have value "communication".

How should I write this condition on SPARQL?

the result must show data that contain the value in ?hasTitle OR in ?hasKeyword. 

I've try OPTIONAL {filter regex(?hasTitle, "communication", i)} . filter regex(?hasKeyword, "communication", "i").

the result: i get all ?hasKeyword with that value, and doesn't get all ??hasTitle with that value

I've also try OPTIONAL {filter regex(?hasKeyword, "communication", i)} . filter regex(?hasTitle, "communication", "i").

the result: i get all ?hasTitle with that value, and doesn't get all ??hasKeyword with that value

if I use UNION for both of them, it has no result found.

Please help me for that.

Hi Dhira,

People on this mailing list are all volunteers. If someone knows the answer to your question chances are they'll reply you (give it a few days). No need to resend your email multiple times or contact people directly.

In your case I'd advice to try the query you're attempting on a different SPARQL Endpoint library, to see if it's a bug with ARC2 directly or just that your SPARQL query is not correct. You have two options:

1) install another RDF store with SPARQL endpoint on your machine, load your data and try to run SPARQL queries against it.

2) find a public SPARQL Endpoint and try to replicate your query on that endpoint using the data of the endpoint. some also allow you to load your data from a remote location.

Okey, Thank You, I'll check them.

Sorry about that, 'cause I'm new here.
