Hi Mathias,
Can you give more details? Is your application for text + ontology, or
ontology only?

For some semweb + full-text searching real-world examples, also look
to the SIMILE project - http://simile.mit.edu/
They have integrated Lucene into PiggyBank and Longwell.

Hi,
I have done some surveys about the information retrieval on the Semantic
Web, (maybe i miss many papers, most papers i used are published in recent
WWW and CIKM conferences, :).

domain ontology to form queries. The first

Hi,
I think one problem of the existing method is that, to query on the RDF
files or similar structures, we have to form SQL like queries. However, for
searching in the text files, we only need to type several keywords. Can we
combine the two methods and how can we combine the two methods. For

hi Erik,
thx for your reply.

Have a look at Kowari - http://www.kowari.org
It is a scalable RDF engine that also has full-text search support
via Lucene.
Professionally I tinker with semweb and search topics, and eventually
we'll have something to show for these efforts :)
