4.The concept of fuzzy pushdown automata is given, and the relation of a fuzzy context-free grammar and a fuzzy pushdown automata is provided, i.e. if and only if a fuzzy language is producal by a fuzzy context-free grammar, it can be accepted by a fuzzy pushdown automaton. So fuzzy context-free Language can be recognized automatically.
首先提出了Fuzzy下推自动机的概念,进而讨论了Fuzzy上下文无关文法与Fuzzy下推自动机的关系,即当且仅当一种Fuzzy语言是由Fuzzy上下文无关文法产生时,该语言可由Fuzzy下推自动机识别,从而达到了自动识别Fuzzy上下文无关语言的目的。收藏指正
5.The syntactic parser applies the GLR algorithm to process the Context Free Grammar(CFG), whose purpose is to extract features of syntactic structure for use by the semantic parser. The syntactic grammar is designed for the trade off between the coverage and the accuracy.
在这一流程中 ,句法分析使用GLR分析器处理上下文无关文法 (CFG) ,获取句子结构特征以便为语义分析服务 ,句法规则照顾到覆盖率和准确率间的平衡。收藏指正
6.The research shows that if and only if a fuzzy language is produced by a max-product fuzzy context-free grammar,it can be accepted by a max-product fuzzy pushdown automaton,so the max-product fuzzy context-free language can be recognized automatically.
研究表明,当且仅当最大乘积型Fuzzy上下文无关文法产生的语言集能被最大乘积型Fuzzy下推自动机接受时,能达到自动识别最大乘积Fuzzy上下文无关语言的目的.收藏指正
