Yesterday, i came to the huge library of the Beaubourg Center (Paris) and read the Kaufmann books called introduction to fuzzy sets. It pointed out exacly where i had a lack of knowledge for my fuzzy search engine. Fuzzy sets are , like discrete sets, very simple to palp. Hence, i envisage to return next week-end to this library to learn the application of fuzzy sets to the ambiguous grammars.
