The article discusses the theoretical foundations of parsing, namely, the definition of LL(1)-grammars and proves the key positions associated with them for practice. The authors demonstrate the impracticality of the proof by definition that context-free...

Multimedia feature graphs are employed to represent features of images, video, audio, or text. Various techniques exist to extract such features from multimedia objects. In this paper, we describe the extension of such a feature graph to represent the me...

A new formalism for the specification of context-free languages is presented. In this formalism, a generalization of the class of nondeterministic finite automata can be obtained by using an auxiliary alphabet and imposing addit...

A grammar-based compressor is an algorithm that receives a word and outputs a context-free grammar that only produces this word. The approximation ratio for a single input word is the size of the grammar produced for this word divided by the size of a sm...

In this paper, a new formalism for specification of context-free languages is proposed. In this formalism, the application of an auxiliary alphabet and the imposition of additional conditions make it possible to obtain an extension of the class of n...
