Class TypedDefaultMiningAssistant

java.lang.Object

amie.mining.assistant.MiningAssistant

amie.mining.assistant.DefaultMiningAssistant

amie.mining.assistant.experimental.TypedDefaultMiningAssistant

public class TypedDefaultMiningAssistant
extends DefaultMiningAssistant

This class overrides the default mining assistant and adds to the rule all possible types constraints on the head variables, that is, it mines rules of the form B ^ is(x, C) ^ is(y, C') => rh(x, y).
