Hi Rupert,
In which revision is it possible to configure such parameters? We are
working with revision 1421282 and I can't see these options in the
Engine Configuration Dialogue.

Hi Rafa
To use the disambiguation engine you will need to tweak the parameters
for the EntityhubLinkingEngine. The relevant parameters are
* Min Label Match Score
"org.apache.stanbol.enhancer.engines.keywordextraction.minLabelMatchFactor"
* Min Matched Tokens
"org.apache.stanbol.enhancer.engines.keywordextraction.minFoundTokens"
see [1] for the documentation
from the Documentation:
If used in combination with an disambiguation Engine one might want to
consider to suggest Entities where only a single token of multi-token
labels do match. In such cases a configuration like Min Matched
Tokens=1 and Min Label Match Score <= 0.5 (e.g. 0.4) might be
considered. With such scenarios users will also want to considerable
increase the value for Max Suggestions (typically values > 10).
I would suggest that you start of with "minLabelMatchFactor=0.33" and
"minFoundTokens=1". In addition I would set the number of suggestions
to ~20.
best
Rupert

Hi all,
I have been trying to use disambiguation-mlt engine with the new EntityHub
Linking Engine for Spanish. My goal is to link and disambiguate with any
kind of entity within the EntityHub, not only with Named Entities. So, I
have configured a new Enhancement Chain including only language detection,
OpenNlpSentenceDetectionEngine, OpenNlpTokenizerEngine, EntityLinkingEngine
and Disambiguation-mlt (installing the bundle version 0.10). After a few
tests, the disambiguation engine is working but is not able to disambiguate
anything. Removing the disambiguation engine from the Enhancement Chain we
have find out that only one candidate for each detected entity is given.
Therefore I think that maybe the disambiguation engine is working fine but
actually doesn't need to disambiguate anything due to only one candidate is
being passed to it from entityHub linking engine.
What can be happening? Our suggestions parameter is set to 5
Thanks. Regards
