Abstract
This paper reviews and relates two default reasoning mechanisms, lexicographic (lex) and maximum entropy (me) entailment. Meentailment requires that defaults be assigned specific strengths and it is shown that lex-entailment can be equated to me-entailment for a class of specific strength assignments. By clarifying the assumptions which underlie lex-entailment, it is argued that me-entailment is a superior method of handling default inference for reasons of both expressiveness and objective justification.
