整个程序还包含了实现乔姆斯基范式的类、从文件读取乔姆斯基范式等关键功能的实现,由于篇幅原因不方便在此博客中全部展示。若要获取完整的可编译源文件,请访问Github:https://github.com/ssaalkjhgf/CYKAlgorithm.git 1//***2//Use CYK algorithm to judge whether the string str is in the Chomsky normal form ...
**CYK算法**(Cocke-Younger-Kasami Algorithm)是一种用于解析上下文无关文法(CFG)的算法,尤其适用于 Chomsky 规范形(CNF)的文法。通过动态规划的方法,CYK算法可以高效判断一个字符串是否属于给定的文法,并通过构建解析表的方式,找到合法的解析树。 ## CYK算法的工作原 字符串 子串 Parse 原创 mob649e815da088...

Currently, very less NLP tools are available to parse several Indian languages. Hence, an effort has been made by us to efficiently parse the structure of the complex sentences in Kannada text using CYK algorithm. It is a bottom-up dynamic programming approach which functions only with the ...

Parsing algorithms for ambiguous CFGs are widespread in areas such as natural language processing, where different parse trees are associated with different semantic interpretations [5]. The Cocke–Younger–Kasami algorithm (CYK) [6,7,8] was the first parsing method for ambiguous CFGs to be ...
