Abstract

The lexical semantics of degree expressions led me to introduce Degree as an ontological category of its own. However, this still leaves open the representational question of which relations on degrees are used to denote degree expressions — an issue which goes beyond the scope of lexical semantics since it calls for an adequate inferencing procedure. In the previous chapter, I used the standard comparison relations on real numbers to represent comparisons between degrees. The following section will make clear that we need more powerful mechanisms to represent degree expressions and to reason on their representation. Hence, a representation and inferencing approach is proposed which outperforms its competitors on all major criteria, even though it is still far from covering all degree expressions in natural language. This approach is also interesting from the point of view of where it originated, viz. temporal reasoning.
