LEAP

LEArning Probabilistic description logics

LEAP learns both the structure and the parameters of DISPONTE KBs exploiting EDGE.

LEAP is based on the system CELOE for ontology engineering and exploits its search strategy in the space of possible axioms. LEAP uses the axioms returned by CELOE to build a KB so that the likelihood of the examples is maximized. LEAP also contains LEAPMR, which exploits EDGEMR to parallelize part of the learning process.
