General
- Why is a file called kim.trusted.entities.cache created in the dictionary folder?
-
kim.trusted.entities.cache contains a binary data structure that contains the dictionary extracted according to the dictionary settings. The name of the file is kept for backwards compatibility with the Ontotext KIM Plaftorm. Note that the file snapshot.properties is a plain text file which contains metadata that, along with the configuration, describe the contents of the binary dictionary.
- Can I extract data from any RDF database?
-
The Large KB gazetteer communicates with RDF databases through the standard open-source Sesame 2 API. The database connection is configured through config.ttl in the dictionary directory which contains standard Sesame configuration template. Note that in order to configure a new database, you will need to add to the classpath the database Sesame adapter.
Here are some databases that should work correctly with the gazetteer.
- Mulgara (formerly known as Kowari) - through the OpenRDF Mulgara SAIL
- OpenLink Virtuoso - through the Virtuoso Sesame Adapter
- Franz Inc. AllegroGraph - through the Sesame 2 SAIL adapter supplied with the AllegroGraph distribution.
- Jena - through RDF2Go
- Can I extract data from a relational database?
-
You should convert your relational data into simple RDF. Try Triplify.
Installation
- How do I install the Large KB Gazetteer?
-
The gazetteer and its companion processing resources form a standard CREOLE plugin, compatible with GATE 5.1. See the CREOLE plugin usage guide in the GATE documentation.
- Can I install the gazetteer in GATE 5.0 ?
-
The gazetteer requires GATE 5.1, but a GATE 5.0 installation can be modified so it becomes compatible. (That is how we tested the gazetteer before the 5.1 release). See the GATE compatibility guide for more information.
