Zusammenfassung:
Semi-unifiability is a generalization of both unification and matching. It is used to check nontermination of rewrite rules. In this paper an inference system is presented that decides semi-unifiability of two terms s and t and computes a semi-unifier. In contrast to an algorithm by Kapur, Musser et al, this inference system comes very close to the one for ordinary unification.
