Hello!
Does bif:contains support relevance? Can I order query results
according to bif:contains?

As per prior post (last week):
## Full Text Score
## Entity Rank
## Surfaced via SPARQL
SELECT ?s ?sc ( <LONG::IRI_RANK> (?s) ) as ?Rank
WHERE { ?s ?p ?o .
?o bif:contains 'NEW AND YOR' option (score ?sc). }
ORDER BY desc (?sc)
Also note this sequence from Nathan which highlights a little bug:
Hi Guys,
Quick bug report:
37000 Error SP031: SPARQL compiler: Internal error:
sparp_find_triple_of_var_or_retval(): triple not found for strong match
SPARQL query:
define sql:signal-void-variables 1 define input:default-graph-uri
<http://dbpedia.org> SELECT * WHERE
{
?s ?p ?o . FILTER( lang(?o) = "en" ) . ?o bif:contains '"xmpp"'
option(score ?attributeScore)
OPTIONAL { ?s rdfs:label ?flabel }
OPTIONAL { ?s <http://dbpedia.org/property/abstract> ?fabstract }
}
to replicate include option(score ?score) to any bif:contains query then
add 2 or more OPTIONAL { } sections to the query, works fine with one.
Many Regards,
Nathan
workaround:
SELECT * WHERE
{
{ ?s ?p ?o . FILTER( lang(?o) = "en" ) . ?o bif:contains '"xmpp"'
option(score ?attributeScore) }
OPTIONAL { ?s rdfs:label ?flabel }
OPTIONAL { ?s <http://dbpedia.org/property/abstract> ?fabstract }
}
note the additional {} prior to optional statements
Kingsley
regards!
