The aim of this paper is to present the structure of a methodological procedure for the specialized text mining through specific keywords applicable to different LSP- text typologies in specialized areas, where the use of a foreign language is unusual. These specific keywords allow those experts in these disciplines - without a deep knowledge of foreign language - to determine a set of informational contents of the mined texts which provide the experts with a better contextualized conceptual understanding of LSP- documentation of their disciplines.
