> Key: STANBOL-1128
> URL: https://issues.apache.org/jira/browse/STANBOL-1128
> Project: Stanbol
> Issue Type: New Feature
> Components: Enhancement Engines
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler

> 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.
