Inheritance and properties reasoning
Opened this issue · 4 comments
Let knowledge:
apple is fruit
green is color
fruit is food
fruit has color
Let observation:
green apple
Is there any way using Phillip to reason the following?
food[apple] has color[green]
Phillip cannot perform such reasoning because Phillip is a abductive reasoner and cannot use rules in deductive way.
What Phillip can do is to use rules backwardly and make hypothesis which can explain given observation.
For instance, given observation of "John ate something green" and your KB (and knowledge of "Food is thing to eat"), Phillip applies rules to observation backwardly and will say that thing eaten is an apple.
I see. Thanks. Is there any production ready deductive AND abductive reasoner library? Sorry, I''m not a scientist.
Since abduction and deduction are based on completely different idea, there is not inference model to deal with both (as far as I know).
However, probabilistic deductive inference model (ex. Markov Logic Networks) may be able to answer to your demands.
So I recommend you to try following engines of MLNs:
Yeah, I saw them. No, it's too complex. I need something simple, like Phillip...
