Rupert Westenthaler created STANBOL-1128:
--------------------------------------------
Summary: Implement a Lucene FST based Entity Linking Engine (based
on OpenSextant / SolrTextTagger)
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.
