Olivier Grisel resolved STANBOL-47.
-----------------------------------

    Resolution: Won't Fix

> Currently the EntityMentionEnhancementEngine does two things:
>  - first extract named entities (currently Persons, Organisations and Places) from the content. For this the openNLP framework is used
>  - second recommend up to three Entities as defined in Wikipedia for the named entities found. For this the autotagger component is used.
> Expected Result:
> 1) An engine that provides named entity extraction based on openNLP. This engine creates TextAnnotaion type Enhancements.
> 2) An engine that provides recommendations for entries as defined in dbpedia. This engine consumes TextAnnotation type enhancements and produces EntityType enhancements.
> This would also allow to 
>  - use an other natural language processing framework for the named entity extraction
>  - use other engines to calculate entity recommendations for text annotations.
> Comment 2 by project member rupert.westenthaler, Jun 17, 2010
> Current state:
> There are two new Engines:
>  - eu.iksproject.fise.engines.opennlp.impl.NamedEntityExtractionEnhancementEngine:
> This engine uses openNLP to perform Named Entity extraction. It has still a dependency to the configured autotagging provider, because the models of openNLP are loaded via this bundle context.
>  - eu.iksproject.fise.engines.autotagging.impl.EntityMentionEnhancementEngine
> This engine uses the autotagger to calculate entity recommendations for TextAnnotations.
> Both EnhancementEngines implement the ServiceProperties interface to parse information about ordering. 
> The NamedEntityExtractionEnhancementEngine needs to run first, because it produces the TextAnnotations consumed by the EntityMentionEnhancementEngine.
> TODOs: Remove the dependency of the opennlp-ner bundle to the configured autotagging provider bundle
> Also split up the unit tests
