Hi Joseph:
The reason for your results is the "Min Label Score"
(enhancer.engines.linking.minLabelScore) parameter of the
EntityLinkingEngine.
Copied from [1]
* Min Label Score (enhancer.engines.linking.minLabelScore)
[0..1]::double: The "Label Score" [0..1] represents how much of the
Label of an Entity matches with the Text. It compares the number of
Tokens of the Label with the number of Tokens matched to the Text. Not
exact matches for Tokens, or if the Tokens within the label do appear
in an other order than in the text do also reduce this score. Entities
are only considered if at least one of their labels cores higher than
the minimum for all tree of Min Labe Score, Min Text Match Score and
Min Match Score.
The default value of this parameter is "0.75".
In your case where "cette plombier moustachu" is matched against "le
plombier moustachu" the actual label match score is only "0.667" (2/3
tokens of the label do match the text). Because of that the Entity is
not linked in that case.
If you would like to link Entities where two out of tree tokens match
with the text you should lower the configuration of minLabelScore to
values < "0.66" e.g.
enhancer.engines.linking.minLabelScore="0.55"
NOTE: As this property is not included in the configuration dialog of
config tab of the Felix Webconsole you will need to set it directly
via the config file of the engine instance. See [2] how to mange your
configuration within the 'stanbol/fileinstall' folder.
To create a configuration file for the EntityhubLinkingEngine you can
follow the following steps
1. To get a config file to start with just go look at
'stanbol/config/org/apache/stanbol/enhancer/engines/entityhublinking/EntityhubLinkingEngine'
and take the '{uid}.config' files of the engine you are currently
using.
2. Next you will need to name the file like
"org.apache.stanbol.enhancer.engines.entityhublinking.EntityhubLinkingEngine-{configname}"
where {configname} should be a human readable name for your
configuration.
3. Now you can edit the file using a TextEditor:
* remove the "service.bundleLocation", "service.factoryPid" and
"service.pid" keys. Those are set by the OSGI environment and should
not be in the config
* add the configuration of the minLabelScore property
'enhancer.engines.linking.minLabelScore="0.55"'
* you can change/add other configuration parameters as described in [1]
4. Finally you need to (1) delete the current configuration of your
engine via the "config" tab of the Felix Webconsole and (2) copy your
configuration file to the 'stanbol/fileinstall' folder.
