Welcome to ProQua
ProQua demo is available here.
ProQua is a new probabilistic database system which combines information retrieval concepts with database technologies. In contrast to other state-of-the-art probabilistic database systems ProQua supports complex logic-based similarity conditions and integrates a logic-based weighting approach for similarity conditions into probabilistic databases. In fact, it is the only system which provides a generic similarity operator for expressing complex logic-based conditions within a probabilistic query language.
