Re: Big data vs Apachi Jena
Dear Kumar,
Semantic Web techs are definitely a valuable approach to master the variety dimension of big data.
In my work on Stream Reasoning [1], I use Jena in memory and esper [2] to master the velocity and variety dimensions at once with the C-SPARQL engine [3].
I would not use Jena TDB to master volume and variety dimensions at once, but you may want to check out the Optique EU project [5] for Semantic Web techs used to this end.
Enjoy,
Emanuele

Thank you Bob but I have seen some recently research combining these both
technologies like "Big data modeling using semantic tech" and something
related. If not with Apache Jena, can we combine these two technologies
like big data modeling or big data and triple stores or so?

to say you can't process large data sets in parallel using Jena - but that
would be big data in the very general sense.

Dear Kumar,
The questions and the answers to this and previous emails (may be with the exception of the first one) do not belong to Jena mailing list. If you want, write me directly.
More generally, I recommend you to get from the library a book about Semantic Web and study it. I believe the correct path to interact with people in any field is: study on your own, try to solve some task, get stuck in some dead-end, try to understand how to escape asking precise and short questions.
Best Regards,
Emanuele

Hello can we use CSPARQL with normal RDF and ontology i-e without RDF streaming? If we have existing ontology , how can we use CSPARQL instead of SPARQL to query the ontology ?

Hello sir,
I have read the links you provided about the RDF streaming and CSPARQL and got some idea too.
But I do not know what to do next. What areas can we select from it for my master thesis. Can you, kindly, point out some problem domains for me so that I can at least proceed in a direction?
Best regards
