Machine Learning and Data Mining systems for the standard representations in the context of the Semantic Web.

Systems and Applications

  • KNN-ALC K-Nearest Neighbor classification algorithm applicable to individuals in ALC ontologies (two structural/semantic dissimilarity measures are exploited)
  • KNN-DL K-Nearest Neighbor classification algorithm applicable to individuals in OWL-DL ontologies (a feature-driven semi-distance is exploited)
    QHDDNN New release of the previous. Works on any query concept
  • ALC-SVM Application of kernel methods (a Support Vector Machine) to individuals in ALC ontologies (a structural/semantic kernel for ALC is exploited)
  • DL-SVM Application of kernel methods (a Support Vector Machine) to individuals in OWL-DL ontologies (a feature-driven kernel for OWL-DL is exploited)
  • BAM Bisecting Around Medoids algorithm applied to OWL-DL ontologies exploiting the feature based semi-distance to obtain hierarchical clusterings
  • Evo Custering DL Flat conceptual clustering algorithm. Both the semi-distance and optimal clustering is learned by means of evolutionary algorithms
  • DL-Link A hierarchical conceptual clustering algorithm for ALC / ALE resources exploiting the notion of Good Common Subsumer
  • DL-Foil Foil-like learner of DL concepts from assertions. Exploits incomplete refinement operators and an ad hoc gain measure
  • ReduCE inducer of OWL classifiers based on a Reduced Coulomb Energy network model
  • TermiTIS induction of terminological decision trees
  • MoTo hybrid ontology matching system
  • DL-Fuzzy Clustering a fuzzy clustering system for individuals in ontologies
  • DL-KPRank an inductive ranking system for individuals in ontologies
