In the present report we give a thorough exposition of our first steps towards a theory
of fuzzy semantics and towards the development of a closed domain question answering
system in the form of a natural language database interface that produces result sets
with records ranked according to the degree to which they fulfill our intuitions about
vague expressions in natural language, and vague adjectives in particular.
We outline our ordering-based approach to semantics and introduce some of the issues
involved in modelling vagueness. We show how fuzzy sets can be used as intermediate
semantic representations of vague expressions. From the family of possible fuzzy logics
we pin down which one best fits our modelling needs in fuzzy semantics.
We then describe the overall design of a controlled experiment involving human subjects,
the software infrastructure necessary for administrating it and the statistical analyses
required to draw conclusions from the data about the adequacy of our model of fuzzy
semantics. We will also discuss the results from a small-scale preliminary instantiation of
this experiment.
Finally we show how we could put those theoretic insights to use in a working natural
language interface to a database that produces rankings of "small cities" or "rainy cities
near San Francisco".
