• KurzfassungAbstract
  Unification of concept terms in Description Logics can be used to determine whether a newly introduced concept may have already been defined before, possibly using other atomic names or modelling concepts on a different level of granularity. We show that unification of concept terms in the small concept description language ${cal FL}_0$ can be reduced to unification modulo an appropriate equational theory. Using results from unification theory, we can further reduce this unification problem to a formal language problem, which can be solved (in Exptime) with the help of tree automata. It can also be shown that the problem is PSPACE hard.
