Center node: "consistency checking and querying in probabilistic databases under integrity constraints"
  Abstract: We address the issue of incorporating a particular yet expressive form of integrity constraints (namely, denial constraints) into probabilistic databases. To this aim, we move away from the common way of giving semantics to probabilistic databases, which relies on considering a unique interpretation of the data, and address two fundamental problems: consistency checking and query evaluation. The former consists in verifying whether there is an interpretation which conforms to both the marginal probabilities of the tuples and the integrity constraints. The latter is the problem of answering queries under a "cautious" paradigm, taking into account all interpretations of the data in accordance with the constraints. In this setting, we investigate the complexity of the above-mentioned problems, and identify several tractable cases of practical relevance.

Connected through hyperedge HE-1 (induced by source paper "a credal extension of independent choice logic"):

    - "on the semantics and complexity of probabilistic logic programs"
    - "inference and learning in probabilistic logic programs using weighted boolean formulas"
