The reason this works is that adding an a using this grammar requires adding an additional b as well; by making sure that every production preserves the desired property (that the number of as is the same as the number of bs), we've ensured (by induction, since the property ...
A context-free grammar-based language model for string recognition has been developed. The developed language model is implemented as a set of graphs which are equivalent to a recursive transition networks. This graph-structured model is not only more compact in memory size than the trie-...
On the index of a context-free grammar and languageformal languagesgrammars/ C4210 Formal logicAn example is given of a context-free grammar with infinite index. This solves a problem proposed by Brainerd. The notion of index is extended to concern context-free languages, and an example is ...
yanshi is a finite state automaton generator like Ragel. Use inline operators to embed C++ code in the recognition of a language. yanshi is enhanced with features to approximate context-free grammar: Approximation of substring grammar Approximation of recursive automaton to match expressions with recurs...

in the garage, and not elsewhere.”Flying planes can be dangerousisambiguousbecause it may mean either (1) “Planes that fly can be dangerous” or (2) “It is dangerous to fly planes.” On the other hand, such “ambiguities” almost always disappear when the sentences are seen incontext...
Recently, computers’ ability to create language is getting much more attention. In fact, the text part ofgenerative AIis a form of natural language generation. Today’s NLG is essentially a very sophisticated guessing game. Rather than inherently understanding the rules of grammar,generative AI mo...
Vietnamese grammar is relatively straightforward as it is an isolating language, which means that it relies heavily on word order and context rather than inflection. The typical sentence structure follows a Subject-Verb-Object (SVO) order. For example, "Tôi ăn cơm" translates to "I ...
I want to check whether the given language L is context free or not. CFG make use of PDA which uses stacks. So, first store each 'a' to the stack. Then pop twice for each occurrence of 'b'. Is this logic correct? context-free-grammar computation-theory pushdown-automaton context-free...
