Inference example:
|
|
|
|
Given
|
|
airport_kb = kb.from_facts([
|
|
('is', 'N29EO', 'Plane'),
|
|
('at', 'N29EO', 'dia'),
|
|
('is', 'N10IV', 'Plane'),
|
|
('at', 'N10IV', 'oak'),
|
|
('is', 'N33FR', 'Plane'),
|
|
('at', 'N33FR', 'lga'),
|
|
('is', 'dia', 'Airport'),
|
|
('is', 'lga', 'Airport'),
|
|
('is', 'oak', 'Airport'),
|
|
])
|
|
|
|
fly = actions.Action(
|
|
[('is', '?subject', 'Plane'), ('is', '?object', 'Airport')],
|
|
[('at', '?subject', '?object'),],
|
|
[('at', '?subject', '?current'),],
|
|
[('at', '?subject', '?object')])
|
|
|
|
Should be able to do something like:
|
|
> infer(airport_kb, [fly], ('at', 'N10IV', 'lga'))
|
|
('fly', 'N10IV', 'lga')
|
