query: What is the difference between vagueness and fuzziness according to Lotfi A. Zadeh?
answer: According to Lotfi A. Zadeh, vagueness means insufficient specificity, while fuzziness means unsharpness of class boundaries.  He gave the example of "I will be back in a few minutes" as fuzzy but not vague, and "I will be back sometime" as both fuzzy and vague.
