| 摘 要： | 给出了当格半群满足交换律时,任何格值上下文无关文法都与格值Greibach范式文法等价,并利用Zadeh扩张原理,研究了格值Greibach范式文法对基于词的计算,最后得出文法对基于词的计算最终由对基于值的计算来实现。

| Abstract: | The lattice-valued context-free grammar is equivalent to the lattice-valued Greibach grammar when the lattice semigroups satisfy the commutative laws.According to Zadeh's extension principle,computing with words via lattice-valued context-free grammar is studied.Finally,this principle indicates that computing with words can be implemented with values with the price of a big amount of extra computations. |
