to non-linguistic disciplines or linguistic models that are open to the rest of the human, social, natural and
pure sciences. It draws up model of Corpus linguistics as a contemporary branch of applied linguistics, in
relation, specifically, to the critical discourse analysis approach, and as an introduction for the of discourse
study based on computer science, mathematics and linguistics. Therefore, the objective of the study is to
clarify this synergy between the two disciplines, to clarify its identity and its most prominent terms, and to
highlight some of its aspects and models.
