Abstract
Class expression learning is a branch of explainable supervised machine
learning of increasing importance. Most existing approaches for class
expression learning in description logics are search algorithms or
hard-rule-based. In particular, approaches based on refinement operators suffer
from scalability issues as they rely on heuristic functions to explore a large
search space for each learning problem. We propose a new family of approaches,
which we dub synthesis approaches. Instances of this family compute class
expressions directly from the examples provided. Consequently, they are not
subject to the runtime limitations of search-based approaches nor the lack of
flexibility of hard-rule-based approaches. We study three instances of this
novel family of approaches that use lightweight neural network architectures to
synthesize class expressions from sets of positive examples. The results of
their evaluation on four benchmark datasets suggest that they can effectively
synthesize high-quality class expressions with respect to the input examples in
under a second on average. Moreover, a comparison with the state-of-the-art
approaches CELOE and ELTL suggests that we achieve significantly better
F-measures on large ontologies. For reproducibility purposes, we provide our
implementation as well as pre-trained models in the public GitHub repository at
