Abstract

The invention relates to a Chinese place name phonetic spelling standardization method. According to the obtained place name type, a corresponding Chinese keyword dictionary is constructed, and the best matching and automatic word segmentation of the keywords in the place name are completed by combining the character string label. Then, the operation of transforming place names into pinyin and spelling standardization is carried out, and finally the Chinese place names are transformed into the corresponding pinyin elements of the spelling standard. The word segmentation method of the inventioncan avoid word segmentation ambiguity, improve word segmentation efficiency, and solve the problem of automatic word segmentation of Chinese place names under the requirements of large amount of data, rich semantics and complex types of Chinese place names in a Chinese place names database. The paper realizes the Chinese place name phonetic transformation and the standardization of phonetic spelling in Chinese place name database, and solves the problem of Chinese place name phonetic transformation and standardization spelling in Chinese place name database with a large amount of data.

Description

technical field [0001] The invention belongs to the field of geographic information systems, and is used for automatic word segmentation and pinyin conversion of Chinese place names in a place name database, and finally realizes the standardization of pinyin spelling of Chinese place names. Background technique [0002] Chinese place names are an important attribute of geographic information, and their corresponding standardized pinyin is an important bridge to assist in the cognition of Chinese place names on maps. With the continuous development of the field of geographic information systems, in order to standardize the spelling of place names in Chinese, the China Geographical Names Committee, the Chinese Character Reform Committee and other institutions have authorized the publication of a set of standard names of Chinese characters, pinyin standards and spelling specifications. However, Chinese place names are often characterized by a large amount of data, rich semantic...
