    • Extracting Rules from Neural Networks with Partial Interpretations 

      Persia, Cosimo Damiano; Ozaki, Ana (Journal article; Peer reviewed, 2022)
      We investigate the problem of extracting rules, expressed in Horn logic, from neural network models. Our work is based on the exact learning model, in which a learner interacts with a teacher (the neural network model) via ...

    • Learning Description Logic Ontologies: Five Approaches. Where Do They Stand? 

      Ozaki, Ana (Journal article; Peer reviewed, 2020)
      The quest for acquiring a formal representation of the knowledge of a domain of interest has attracted researchers with various backgrounds into a diverse field called ontology learning. We highlight classical machine ...

    • Mining EL⊥ Bases with Adaptable Role Depth 

      Guimaraes, Ricardo; Ozaki, Ana; Persia, Cosimo Damiano; Sertkaya, Bariş (Journal article; Peer reviewed, 2023)
      In Formal Concept Analysis, a base for a finite structure is a set of implications that characterizes all valid implications of the structure. This notion can be adapted to the context of Description Logic, where the base ...
