usage of entityhub/yard/solr
Hi,
I am trying to use the entityhub/yard/solr module to directly query the
dbpedia.solrindex.
I have unzipped the dbpedia.solrindex.zip file
in entityhub/yard/solr/target/indexes/default folder.
And modified the Solryardtest.java as given below but unable to find any
results. Am I missing something?
public static final String TEST_SOLR_CORE_NAME = "dbpedia";
@Test
public void testFieldQuery() throws YardException {
Yard yard = getYard();
String field = "rdfs:label";
TextConstraint tc = new TextConstraint("Roger Federer",
PatternType.wildcard, false, "en");
FieldQuery query = yard.getQueryFactory().createFieldQuery();
query.addSelectedField(field);
query.setOffset(0);
query.setLimit(10);
query.setConstraint(field, tc);
QueryResultList<Representation> results = yard.find(query);
Representation result;
Iterator<Representation> it = results.iterator();
log.info("Number of results: " + results.size());
}

I'm interested in that too, but I was thinking:

Can you try from a deployed instance rather than a unit test? I think
you should just copy the zipfile to {stanbol-working-dir}/datafiles
without extracting it, then configure the Solr Yard?

Hi Manish Aggarwal
Sorry for the late replay, but I was offline the whole last week.
The above Exception indicates, that you try to use a Solr 4 index with
Solr 3.6 libs in the classpath. I think this is because you use the
release version of o.a.stanbol.commons.solr.* that do use Solr 3.6.
In this case you will also need to use a dbpedia.solrindex.zip that
was build with a Entityhub Indexing tool version that was still using
Solr 3.6.

Re: usage of entityhub/yard/solr
Posted by Manish Aggarwal <ma...@gmail.com>.
A typo in my previous mail ..
"please note that I unzipped a valid dbpedia.solrindex.zip file at
location ${basedir}/target/indexes/default"
Also, this is how I was initializing SolrYard for version 0.12.0-SNAPSHOT
where things were working ....
@BeforeClass
public static final void initYard() throws YardException, IOException {
String prefix = System.getProperty("basedir") == null ? "." :
"${basedir}";
String solrServerDir = prefix + TEST_INDEX_REL_PATH;
log.info("Test Solr Server Directory: " + solrServerDir);
SolrYardConfig config = new SolrYardConfig(TEST_YARD_ID,
TEST_SOLR_CORE_NAME);
config.setName("Solr Yard Test");
config.setDescription("The Solr Yard instance used to execute the
Unit Tests defined for the Yard Interface");
config.setAllowInitialisation(false);
System.setProperty(ManagedSolrServer.MANAGED_SOLR_DIR_PROPERTY,
solrServerDir);
IndexReference solrServerRef =
IndexReference.parse(config.getSolrServerLocation());
solrServerProvider =
StandaloneEmbeddedSolrServerProvider.getInstance();
SolrServer server = solrServerProvider.getSolrServer(solrServerRef,
config.isAllowInitialisation() ?
config.getIndexConfigurationName() : null);
//Optional support for the nsPrefix service
final NamespacePrefixService nsPrefixService;
ServiceLoader<NamespacePrefixService> spsl =
ServiceLoader.load(NamespacePrefixService.class);
Iterator<NamespacePrefixService> it = spsl.iterator();
if(it.hasNext()){
nsPrefixService = it.next();
} else {
nsPrefixService = null;
}
yard = new SolrYard(server, config, nsPrefixService);
}
There is a way (in version 0.12.0-SNAPSHOT as shown above) to pass SolrServer
in SolrYard constructor. But it is not present in 0.11.0 version, how to
achieve the same for version 0.11.0.

Re: usage of entityhub/yard/solr
Posted by Manish Aggarwal <ma...@gmail.com>.
Hi Rupert,
I got it working for version 0.12.0-SNAPSHOT, but as version 0.12.0 is
still not available through maven repository, I switched to version 0.11.0
which seems to be quite different.
Here is what I am doing for version 0.11.0 ...
public static final String TEST_YARD_ID = "testYard";
public static final String TEST_SOLR_CORE_NAME = "dbpedia";
protected static final String TEST_INDEX_REL_PATH = File.separatorChar
+ "target" + File.separatorChar
+
ManagedSolrServer.DEFAULT_SOLR_DATA_DIR;
private static final Logger log =
LoggerFactory.getLogger(SolrYardTest.class);
@BeforeClass
public static final void initYard() throws YardException {
// get the working directory
// use property substitution to test this feature!
String prefix = System.getProperty("basedir") == null ? "." :
"${basedir}";
String solrServerDir = prefix + TEST_INDEX_REL_PATH;
log.info("Test Solr Server Directory: " + solrServerDir);
System.setProperty(ManagedSolrServer.MANAGED_SOLR_DIR_PROPERTY,
solrServerDir);
SolrYardConfig config = new SolrYardConfig(TEST_YARD_ID,
TEST_SOLR_CORE_NAME);
config.setName("Solr Yard Test");
config.setDescription("The Solr Yard instance used to execute the
Unit Tests defined for the Yard Interface");
//use the default Solr Index configuration for this tests
config.setDefaultInitialisation(false);
// create the Yard used for the tests
yard = new SolrYard(config);
}
@Override
protected Yard getYard() {
return yard;
}
@Test
public void testFieldQuery() throws YardException {
Yard yard = getYard();
String field = "rdfs:label";
TextConstraint tc = new TextConstraint("sachin tendulkar",
PatternType.wildcard, false, "en");
FieldQuery query = yard.getQueryFactory().createFieldQuery();
query.addSelectedField(field);
query.addSelectedField(NamespaceEnum.rdf + "type");
query.setOffset(0);
query.setLimit(5);
query.setConstraint(field, tc);
QueryResultList<Representation> results =
yard.findRepresentation(query);
Representation result;
Iterator<Representation> it = results.iterator();
while ( it.hasNext() ) {
result = it.next();
log.info("ID: " + result.getId());
Iterator<Object> type_it = result.get(NamespaceEnum.rdf +
"type");
while (type_it.hasNext() ) {
log.info("type: " + type_it.next());
}
}
}
And I am getting the following error (also please note that I unzipped a
valid dbpedia.solrindex.zip file at location ${basedir}/target/indexes ) ..

What I am doing wrong? How to initialize a SolrYard with the existing
dbpedia index??
Thanks in advance!!

Re: usage of entityhub/yard/solr
Posted by Rupert Westenthaler <ru...@gmail.com>.
Hi Manish,
I think you need to use the full URI for rdfs:label. QNAME support is
implemented on the RESTful service layer and not supported when using
the Java API.
So changing
String field = NamespaceEnum.rdfs + "label";
should solve your issue (assuming that the initialization with the
dbpedia index was successful)
