Current research

My overall project is to look at the relationship between fuzzy concepts and contexts, with the aim of providing an account that incorporates fuzzy logic and context-sensitive semantics.

A concept is fuzzy if it is gradable or applicable to greater or lesser degrees. For example, take the concept of being old, there does not appear to be a definite threshold for oldness. Oldness comes in degrees. Natural language sentences containing fuzzy concepts are thus true or false to a certain extent or in certain respects.

The existence of fuzzy concepts has motivated logicians and semanticists to consider fuzzy logic, which is an infinite-valued logic that allows a sentence to be true to a certain degree – rather than employ clear truth and falsity in every case. Fuzzy logic seems to be able to account for the fuzzy concepts, thus still proving a means to deal with natural language sentences (which contain fuzzy concepts) in a somewhat systematic manner.

I am looking at different linguistic phenomena, analysing how they behave in different contexts, and using fuzzy semantics to try and account for them. Specifically, I am focusing on: pure indexicals and demonstratives; gradable adjectives; predicates of personal taste; and expressives.
