This is useful for ontology analysis, ontology reuse and privacy. Lethe  is a tool for performing uniform interpolation on ontologies in expressive description logics, and it can be used from the command line, using a graphical interface, and as a Java library. It furthermore implements methods for computing logical difference and performing abduction using uniform interpolation. We present the tool together with an evaluation on a varied corpus of realistic ontologies.Description logicsForgettingNon-classical reasoningUniform interpolationText/Journal Article10.1007/s13218-020-00655-w1610-1987
