 With this method, language learners are given the opportunity to categorize language data from the corpus and subsequently form conclusions about the patterns and features of their target language from their categorizations.This method involves a greater amount of work on the part of the language leaner and is referred to as “data-driven learning” by Tim Johns.The corpus data used for data-driven learning is relatively smaller, and consequently the generalisations made about the target language may be of limited value.
