Comparative expressions (CEs) such as "big- ger than" and "more oranges than" are highly ambiguous, and their meaning is context depen- dent. Thus, they pose problems for the semantic interpretation algorithms typically used in nat- ural language database interfaces. We focus on the comparison attribute ambiguities that occur with CEs. To resolve these ambiguities our nat- ural language interface interacts with the user, finding out which of the possible interpretations was intended. Our multi-level semantic processor facilitates this interaction by recognizing the oc- currence of comparison attribute ambiguity and then calculating and presenting a list of candi- date comparison attributes from which the user may choc6e.
