KIF — Knowledge Integration Framework

KIF is a knowledge integration framework from IBM Research.

KIF is based on Wikidata and it's licensed under the Apache-2.0 license.

First time here? Check out the quickstart guide.

Highlights

• KIF can be seen as a Python interface to query Wikidata (RDF).

• KIF queries are written in the KIF pattern language, which is based on Wikidata's data model.

• KIF can be used to query knowledge sources other than Wikidata, provided proper SPARQL mappings are given.

• KIF comes with built-in mappings for DBpedia and PubChem RDF. Other mappings can be added programmatically.

Hello world!

Prints an arbitrary statement from Wikidata:

from kif_lib import *
from kif_lib.compiler.sparql.mapping.wikidata import WikidataMapping
kb = Store('sparql2', 'https://query.wikidata.org/sparql', WikidataMapping())
print(next(kb.filter()))

Prints an arbitrary Wikidata-like statement from DBpedia:

from kif_lib import *
from kif_lib.compiler.sparql.mapping.dbpedia import DBpediaMapping
kb = Store('sparql2', 'https://dbpedia.org/sparql', DBpediaMapping())
print(next(kb.filter()))

Installation

$ pip install kif-lib
