Text Search Using Lucene

[Kumar,Abhishek]

Hi,


I am trying to implement text search in Jena via Fuseki. I have followed 
through the documentation and created assembler file.


But after starting fuseki server using config parameter - there is no data in 
the dataset and thus returns no results for simple query or text query.


What I have tried so far

1. Built the TDB dataset using java -cp $FUSEKI_HOME/fuseki-server.jar 
tdb.tdbloader --tdb=assembler_file data_file

2. Built the index using java -cp $FUSEKI_HOME/fuseki-server.jar 
jena.textindexer --desc=assembler_file

3. Started the fuseki server using fuseki-server --config ../assembler_file.ttl


I tried the answer on Stackoverflow 
http://stackoverflow.com/questions/30447536/fuseki-indexed-lucene-text-search-returns-no-results


but using --desc gives error no service name.


Another user had similar issue a year ago as in this thread 
http://thread.gmane.org/gmane.comp.apache.jena.user/7892 but there are no 
solutions there as well.


Can someone please help here?


Thanks & Regards

Hi all,


What is the expansion of the acronym ARQ - the query engine for Jena?

Granatum http://www.fit.fraunhofer.de/en/fb/cscw/projects/granatum.html is
a Cancer research project that uses Jena to query across multiple databases
with differing vocabularies.  A custom query engine built on Jena does
automatic query translation and partitioning for each endpoint as necessary.

Applications/Projects Using Jena

[Kumar,Abhishek]

Hi Team,

I am a Masters student at University of Florida. I am presenting Apache Jena to 
our class as part of research on RDF and semantic web. I have got material to 
speak about Jena but I am having trouble finding some use cases of Jena in 
current industry.

I read that many Semantic web applications use Jena but I could not find any 
project which uses Jena. Can you help provide names of some projects which are 
currently using Jena? That would be very helpful to generate interest among 
students.

Thanks & Regards
Abhishek Kumar
