Rupert Westenthaler created STANBOL-590:
-------------------------------------------
Summary: LDPath processor operating on the IndexingSource and
Implementation for the JenaTDB based indexing source.
Key: STANBOL-590
URL: https://issues.apache.org/jira/browse/STANBOL-590
Project: Stanbol
Issue Type: Sub-task
Components: Entity Hub
Affects Versions: 0.10.0-incubating
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Fix For: 0.10.0-incubating
This LDPath processor would allow to use the full LDPath functionality based on
the Data of the IndexingSource.
Configuration of such a processor would be also easy as the IndexingSource is
already present for every indexing process.
This requires IndexingSurces to implement RDFBackend. This can be easily done
for the Jena TDB based indexing source.
This feature would be very useful for calculating the "semantic context" of
Entities. Such as following related Entities and indexing their labels with the
current Entity. This information may be later used for similarity searches such
as Solr MLT.
However the same feature might also be used materialize transitive, symmetric
and/or inverse properties in indexed datasets.
Users need to NOTE that indexing time will increase if using those features as
execution configured LDPath programms will cause a lot of additional requests
to the IndexingSource.
