The aim is to extend the CLARIN-PL research infrastructure to a research and development platform for natural language processing and large language data mining. It will provide access to universal language technology components and mechanisms to combine them for the construction of text analysis systems. Infrastructure for the construction of efficient and efficient systems for large language data mining (text and speech) will be developed. Specific objectives: 1.creation of a technology centre – a database for language data mining technologies; 2.equipment of the centre with advanced language technologies for intelligent processing of large heterogeneous data in areas not supported by existing research infrastructures or open technology; 3.Providing tools for analysing language data in a simple, structured and recorded form to the market; 4.to achieve a unified and interoperable form of multiple resources and language tools for European languages; 5.develop and implement appropriate standards for language resources and tools; 6.provide comprehensive and easy access to the archive of language resources and technologies, as well as a range of applications for end-users.
