nifconverter's Introduction

nifconverter

Build Status Coverage Status PyPI version

Utility to translate NIF files across identifier schemes, for instance between DBpedia and Wikidata.

It can be used both as a Python library or as a CLI utility.

Install it with pip install nifconverter.

Example invocation:

nifconverter -i my_dbpedia_nif_file.ttl -o my_wikidata_nif_file.ttl

By default we use the DBpedia SameThing service to convert URIs. It is also possible to query the DBpedia SPARQL endpoint instead using the --converter parameter:

nifconverter --converter FromDBpediaSparqlConverter -i my_dbpedia_nif_file.ttl -o my_wikidata_nif_file.ttl

The target URI space to convert to can be changed with the --target option:

nifconverter --target https://en.wikipedia.org/wiki/ -i my_wikidata_nif_file.ttl -o my_wikipedia_nif_file.ttl

nifconverter's Issues

Add cross-language DBpedia IRI support

Would you consider switching from SPARQL to DBpedia's Same Thing Service for converting DBpedia URIs?

This should be quite a bit faster than the SPARQL endpoint, and provides links between Wikidata, DBpedia Global IRIs, and all localized DBpedias. The hosted service can take on hundreds of concurrent requests -- thousands if it's lucky with cache hits. For users who want the lowest possible latency, hosting their own instance should be a breeze with the provided docker-compose file.

An example lookup for an Esperanto URI:
https://global.dbpedia.org/same-thing/lookup/?meta=off&uri=http://eo.dbpedia.org/resource/Geometrio

I haven't used nifconverter yet, but I'm looking into it for converting some older entity linking datasets to more stable URIs. If this works out, I might be able to submit a PR.

(and yes: this is a shameless plug. I am the main author of the microservice.)
