Rupert Westenthaler resolved STANBOL-1128.
------------------------------------------

    Resolution: Fixed

resolved with http://svn.apache.org/r1528716

The engine is included in the default build. Its available in both the stable and the full launcher. A default configuration for FST linking against the default dbpedia dataset was also added (chain name: dbpedia-fst-linking)

> This will implement an in-memory EntityLinking EnhancementEngine based on Lucenes FST (Finite State Transducer) technology.
> This engine could make direct use of the Classes contained in the OpenSextant / SolrTextTagger code [1]. This uses a two layered FST 
>     (1) to represent words and 
>     (2) to map those words to phrases
> With this it is possible to efficiently hold big vocabularies in memory (> 300MByte for geonames.org). See the presentation at [2] for more details.
> While the license is fully compatible (ASL 2.0) the library is currently not available on Maven Central. We need to contact the author regarding this.
