And one more concrete question:
Why are some DBPedia concepts missing from spotlight results?
For example, "Leadership" is under http://dbpedia.org/page/Leadership , but
is detected neither with the en2+2 nor en4+8 statistical models. It looks
like it doesn't even spot the surface form, which is strange.
Using the (Lucene?) demo at http://dbpedia-spotlight.github.io/demo/ ,
"Leadership" is detected without problems.
Cheers,
Radim

Předmět: [Dbp-spotlight-users] spotlight concepts
"
Hello all,
I am a new spotlight user -- thanks for the awesome project!
I'd appreciate help with some basic concepts:
1. I read the "statistical" paper [0], and ran the "statistical" backend,
but I'm not clear on which parameters it uses. What is the difference
between en2+2 or en4+8, does it use the language-dependent or independent
version? How do I switch to the language-dependent one?
2. I tried Lucene spotlight 0.5, and it runs out of heap space even with the
smallest spotter dict (threshold 75), with Xmx 22GB, debian with openjdk. Is
that normal or am I doing it wrong? I followed the installation instructions
at [1]. Is there any advantage to the Lucene implementation anyway? When
should I use Lucene vs. statistical?
3. Is there a list of tools like idio's "spotlight editor" [2]? In
particular I'm interested in ways to manually add new "things" to the DB, or
manually tweak detections that are wrong. Is there any support out of the
box? Are there other ways, apart from that idio's editor?
Thank you again for the great tool,
Radim
