Zhiwen Mo · Journal of Sichuan Normal University · 2004
The paper defines fuzzy-context-free tree grammars (FCFTG), discusses the structure of FCFTG and presents the decomposition theorem and representation theorem of FCFTG. Then, the paper discusses the languages IO(inside-out) generated by fuzzy context-free tree grammars. Finally the paper discusses the closure property of fuzzy IO tree languages.
