Practice and Theory of Natural Language Processing

Natural language processing (NLP) is defined as formation and investigation of computationaIly effective mechanism for communicating by natural languages. Practice and theory of NLP is projected by following this defÏnition. The goal of NLP is clarified by comparing with its related fields such as linguistics and cognitive psychology. The spectrum of re. search fields in NLP is broad from scientific to engineering-oriented. Focusing at Korean language processing, it is claimed that several basic problems should be solved, for example, Korean dictionary and bilingual dictionaries for practical use of engineering. Three R&D projects are discussed: Korean intelligent wordprocessing, machine translation, natural language in user interface, for they should be done in the near future. Their problems and complexities are discussed
