FIZzysearch

A SPARQL rewriter that performs enhanced searches

This is an extension of the work that was started at the 2023 HackaLOD event in Gouda. The package provides a SPARQL rewriting framework which can be used to implement different enhanced search facilities like full-text searches or embeddings based searches. The re-writing can be used as a "front-end" to existing SPARQL endpoints, or integrated as a software library. One of the benefits are enabling easier searches for existing triplestores in which it might be cumbersome to install or configure enhanced search facilities.

✨ This library gives you "fizzy" searches! ✨

(and it was made by the FIZ ISE group)

Example

See it in action by running this command in a terminal:

docker run --rm -it -p 8000:8000 -e FTS_FILEPATH=/fts -e DATA_LOAD_PATHS=https://yogaontology.org/ontology.ttl ghcr.io/epoz/shmarql:latest

This will load up a triplestore with an example ontology, and allow fulltext searches over the literals in that store.

Try this query

SELECT * WHERE {
  ?sub <http://shmarql.com/fts> "Sa*" .
}

This demo is from SHMARQL which uses FIZzysearch to add fulltext searches to the triplestore.

TODO

• Add a sample FTS implementation as demo

• Add documentation on how to build the dependencies and where to fetch the SPARQL grammar
