Freemasons of the Language Engineering House with its victories and defeats - yesterday, today, tomorrow (Paris notes in memory of R. G. Piotrowski)
The paper is dedicated to the 90 <sup>th</sup> anniversary of the birth of R. G. Piotrowski and focused not only on his consistent contribution to language engineering, but also the philosophy of science in terms of the linguistic Freemasons. The author considers ways of overcoming the ontological crisis of structural language engineering, linguists and programmers, prospects for development of semantic search engines and corpus linguistics as a revival of applied linguistics.
