汉语句法的分段循环分析策略 A CYCLICALLY SPLITTING A NALYSIS STRATEGY ON CHINESE GRAMMAR 姬东鸿 Ji Donghong 1 first-author 丁川 Ding Chuan 1 吴安平 Wu Anping 1 戴大为 Dai Dawei 1 武汉大学计算机科学系 武汉大学计算机科学系 Department of Computer Science, Wuhan University Department of Computer Science, Wuhan University 定义了汉语的分段语法，并根据自然语言的分段循环结构，提出了汉语的分段循环分析策略．它的基本思想是确定语言的一组基本范畴，其相应的句法规则段及其之间的优先关系，对于每一个句法规则段，分别依次采用改进的Ｋｉｌｂｕｒｙ算法、它的优点在于分析过程中的项目集比较小，而且避免了无用分析树的产生，从而大大提高了分析效率． A splitted grammar for Chinese languague is proposed, and a cyclicallysplitting strategy, paralled with cycllcally splitting structures of natural languages, for parsing Chinese is put forward. Its main idea is to establish a group of basic categeries,corresponding grammar phases. and the precedencc relation among them, and to impose the improved Kilbury’s algorithm on every grammar phase in turn. Compared with pure Kilbury’s or Early’s algorltllnls, the items is decreased, and many useless parse trees are avoided. So the parse efficiency is improved. 机器词典 句法范畴 句法分析 机器翻译 lexicon syntactic category syntactic analysis machine translation TP391 国家自然科学基金(61672102) 1995-01-01 2021-04-01 1
