    In a companion paper \cite{Asv:FCF1} we used fuzzy context-free grammars in order to model grammatical errors resulting in erroneous inputs for robust recognizing and parsing algorithms for fuzzy context-free languages. In particular, this approach enables us to distinguish between small errors (``tiny mistakes'') and big errors (``capital blunders''). In this paper we present some algorithms to recognize fuzzy context-free languages: particularly, a modification of Cocke--Younger--Kasami's algorithm and some recursive descent algorithms. Then we extend these recognition algorithms to corresponding parsing algorithms for fuzzy context-free languages. These parsing algorithms happen to be robust in some very elementary sense.
