The Potentials of Corpus Linguistics in Strengthening Critical Discourse Analysis

The article aims to demarcate and tap the potentials of methods of Corpus Linguistics in strengthening Critical Discourse Analysis from the perspectives of dialogical foundations, barriers and measures.It is argued that Corpus Linguistics can not interpret the processes of discourses in sociocultural context, can not handle meaning potentials and still has difficulties in making lexicogrammatical analysis at higher ranks.Accordingly, the potentials are mainly as follows: analyzing texts as products in cotext and intertext, batch processing a large number of meaning actuals, and making lexicogrammatical analysis at lower ranks.Accordingly, some pertinent dialogical measures are proposed to strengthen and enrich Critical Discourse Analysis by borrowing methods from Corpus Linguistics.
