Effective computation of maximal sound approximations of Description Logic ontologies
Published on Dec 19, 20141669 Views
We study the problem of approximating Description Logic (DL) ontologies specified in a source language LS in terms of a less expressive target languageLT. This problem is getting very relevant in pract
