On the relationship between decidable fragments, non-classical logics, and description logics

摘要

The guarded fragment and its extensions and subfragments have often been considered as a framework for investigating the properties of description logics. But there are other decidable fragments which all have in common that they generalise the standard translation of ACC to first-order logic. We provide a short survey of some of these fragments and motivate why they are interesting with respect to description logics.
