Externalized plug-ins

Here is a list of plug-ins which were previously shipped within OWLIM and have been externalized in order to cut the core's dependency on Lucene.

  • FTS - allows you to create full-text search queries through SPARQL
  • Lucene

Newly developed plug-ins

And a list of the latest developments at Ontotext, wrapped as OWLIM plug-ins:

  • Concept Extraction (CES) - provides concept extraction and semantic pipeline management through a SPARQL interface
  • Lucene2 - built on top of Lucene 3.x.x, can be used for searching concept literals and combining FTS and semantic search
  • Lucene4 - builds on top of Lucene2 by using Lucene 4.x.x and allows blazing fast facet queries
