ProbLog
open-in-new
<p>ProbLog is a <a href="/facts/Probabilistic_logic_programming/etqEIEdA">probabilistic logic programming</a> language that extends <a href="/facts/Prolog/r5h66Qh1">Prolog</a> with probabilities. It minimally extends <a href="/facts/Prolog/r5h66Qh1">Prolog</a> by adding the notion of a probabilistic fact, which combines the idea of <a href="/facts/Atomic_formula/s9WMnbqT">logical atoms</a> and <a href="/facts/Random_variable/TwTBXnLT">random variables</a>. Similarly to Prolog, ProbLog can query an <a href="/facts/Atomic_formula/s9WMnbqT">atom</a>. While Prolog returns the <a href="/facts/Truth_value/SY4e2w8l">truth value</a> of the queried <a href="/facts/Atomic_formula/s9WMnbqT">atom</a>, ProbLog returns the <a href="/facts/Probability/fgYvMhwb">probability</a> of it being true. </p>
