Journal of Coastal Research, Special Issue No. 83, pp. 724–728. Coconut Creek (Florida), ISSN 0749-0208. The precise identification of chart symbol is of great significance for ocean sailing. The current recognition methods for chart symbol have obvious shortcomings in recognition efficiency and control accuracy. To address this problem, it is necessary to discuss the construction and implementation of the grammatical rule of chart symbol language from two aspects of theory and practice. In this paper, the grammatical rule and the essential features of chart symbol language are discussed. The transformation of computer language service mode of chart symbol is achieved. Firstly, the description of various chart symbols is carried out by the computer natural language, and the recognition and processing of chart pattern informat...
