Abstract
Incompleteness and vagueness are inherent properties of knowledge in several real world domains and are particularly pervading in those domains where entities could be better described in natural language. In order to deal with incomplete and vague structured knowledge, several fuzzy extensions of Description Logics (DLs) have been proposed in the literature. In this paper, we present a novel Foil-like method for inducing fuzzy DL inclusion axioms from crisp DL knowledge bases and discuss the results obtained on a real-world case study in the tourism application domain also in comparison with related works.

Note that \(0.18 = 0.318 \cdot 0.569\), where \(0.318 = tri(90,112,136)(105)\).
- 3.
\(\mathcal {EL}({\mathbf {D}})\) is a fragment of \(\mathcal {ALC}({\mathbf {D}})\) [26].
- 4.
\(\mathcal {DL}\) stands for any DL.

One such comparison could not be made with DL-Foil since the implemented algorithm was not made available by the authors.
