  bibo_abstract:
  - Link discovery plays a key role in the integration and use of data across RDF
    knowledge graphs. Active learning approaches are a common family of solutions
    to address the problem of learning how to compute links from users. So far, only
    active learning from perfect oracles has been considered in the literature. However,
    real oracles are often far from perfect (e.g., in crowdsourcing). We hence study
    the problem of learning how to compute links across knowledge graphs from noisy
    oracles, i.e., oracles that are not guaranteed to return correct classification
    results. We present a novel approach for link discovery based on a probabilistic
    model, with which we estimate the joint odds of the oracles’ guesses. We combine
    this approach with an iterative learning approach based on refinements. The resulting
    method, Ligon, is evaluated on 10 benchmark datasets. Our results suggest that
    Ligon configured with 10 iterations and 10 training examples per iteration achieves
    more than 95% of the F-measure achieved by state-of-the-art algorithms trained
    with a perfect oracle. Moreover, Ligon outperforms batch learning approaches devised
    to be trained with small amounts of training data by more than 40% F-measure on
    average.@eng
