The boundary is the distinctive with identity and otherness of two other sciences. They have another methodology or theory their own scientific goal. But there are often small overlapping in history or with needs of effective studying. In this point, the hybrid or convergence of two or more sciences is needed. The study of Korean language and literature have been clear bounded traditionary. In this history, two science co-work for self development. This is not real convergence. But language process- ing technology(or NLP), it is originally convergence science of linguistics and computer science, give a good chance to the science which require for the mega data processing(It means the informationization of the science). This co-work(by using text-mining tool etc.) is a good example for the convergence of sciences. But there are more fundamental study and expert for the this sort of cowork.
