keywordLinking engine does not work with words in quotes
Hello,
I have noticed that keywordLinking engine does not work with words in
quotes.
For the given text:
> I suspect that the keyword linking engine does not work with "quotes".
I get the following exception: [1].
[2] Shows the SPARQL Query and Virtuoso error message
It seems that the problem is in the SPARQL query line:
> ?v_1 bif:contains '*"*\"quotes"' .
Stanbol sends the query to Virtuoso with both UNescaped (that should have
been removed) and escaped quote: "*%22*%5C%22quotes%22" - which translates
to *"*\"quotes". Removing the first quote -\"quotes" - solves the problem.
PS. Could you please explain me, what parameter is expected instead of
"null" in ["quotes]@[en, null]? [1]

Hi Gintautas Sulskus
I fixed both issues for both 0.12.1-SNAPSHOT and 1.0.0-SNAPSHOT. See

Re: keywordLinking engine does not work with words in quotes
Posted by Rupert Westenthaler <ru...@gmail.com>.
Hi,
finally got some time to look into that ...
First - my assumption that the patch for STANBOL-877 got not merged
into the codebase was wrong. It is present in both 0.12.1 and trunk.
So this means that both reported errors are indeed new issues.
> PS. Could you please explain me, what parameter is expected instead of "null" in ["quotes]@[en, null]? [1]
null means to search for literals without language tag (the null
language). This is why
FILTER(((lang(?v_1) = "en") || (lang(?v_1) = "")))
is in the SPARQL query
Finally the disambiguation-mlt engine will not work with the SPARQL
backed Enityhub Site. This is simple because SPARQL does not allow
MoreLikeThis queries. Still it does look like as if the unsupported
constraint type results in an additional '.' added to the query. This
needs to be fixed.

Re: keywordLinking engine does not work with words in quotes
Posted by Gintautas Sulskus <gi...@gmail.com>.
Hi,
I will re-use this thread to report a similar SPARQL query construction
issue with "disambiguation-mlt" engine.
The engine fails in an attempt to process the following sentence: "The
House Benghazi committee took its best swings at Hillary Clinton."
Virtuoso throws an invalid syntax exception [1].
However, sentence "Committee took its best swings at Hillary Clinton."
works just fine.
Regards,
Gin
[1]
Virtuoso 37000 Error SP030: SPARQL compiler, line 6: syntax error at
'.' before '?id'
SPARQL query:
define sql:big-data-const 0
#output-format:application/sparql-results+json
SELECT DISTINCT ?id
WHERE {
{
.
?id <http://www.w3.org/2000/01/rdf-schema#label> ?tmp1 .
?tmp1 bif:contains '("hillary" AND "clinton")' .
FILTER(((lang(?tmp1) = "en") || (lang(?tmp1) = ""))) .
}
}
ORDER BY DESC ( <LONG::IRI_RANK> (?id) )
LIMIT 25
Best Wishes,
Gintautas Sulskus

Re: keywordLinking engine does not work with words in quotes
Posted by Rupert Westenthaler <ru...@gmail.com>.
Hi Gin,
Thanks for reporting. This looks like a bug in the generation of the
SPARQL queries by the SparqlQueryUtils.java [1] class.
A search for existing JIRA issues related to this revealed STANBOL-877
[2] that already provided a patch that seamed the have never been
applied to the code base. I try to have a look into this but I might
not find time this week.
best
Rupert
