The strategies of syntactic analysis based on head-driven grammars and the methods of their implementation in information systems

The paper deals with the problems of design and development of syntactic parses in multilingual natural language processing systems, machine translation, and knowledge extraction from texts. The grammar formalisms and approaches to parses construction are considered that take into account such challenges of translation as language transformations. The approach based on the hybrid grammar catching the functional parameters of language structures is proposed.
