What? How?

KIF is a knowledge integration framework based on Wikidata.

• Using KIF, one can easily combine heterogeneous knowledge sources into a virtual knowledge base. This behaves like an extended Wikidata and can be queried uniformly using a simple but expressive pattern language.

• KIF leverages Wikidata's data model plus user-defined mappings to construct a unified view of the underlying knowledge sources while keeping track of the context and provenance of their statements.

• KIF pattern language is based on Wikidata's data model and is embedded in Python—its constructs can be created and operated programmatically from within Python.

Hello world!

Prints an arbitrary statement from Wikidata:

from kif_lib import *      # import KIF namespacee
kb = Store('wikidata')     # create a store pointing to Wikidata
print(next(kb.filter()))   # obtain and print one arbitrary statement

Installation

$ pip install kif-lib
