TĂtulo: Satisfiability in EL with sets of Probabilistic ABoxes Palestrante: Marcelo Finger Resumo: This work studies a probabilistic extension of the lightweight Description Logic EL, called ELPA, that allows for probabilistic assessments on ABoxes. We concentrate on the problem of verifying the satisfiability of an ELPA-knowledge base, proposing algorithms for this problem based on recent advances on probabilistic satisfiability (PSAT).
