《现汉》与《语法信息词典》词类对应分析

Analysis of Parts-of-speech Correspondence Between DCC and GKB

词类标注问题历来受到中文信息处理、汉语语法和词汇学界的共同关注,学者们已提出多种词类标记体系,彼此间存在较大差异,但迄今尚无人对大规模词类标注工程进行系统比较。该文以《现代汉语词典》第5版和《现代汉语语法信息词典》两个大型词典词类标注工程为比较对象,基于所提出的词类对应算法,自动找出两部词典词类标注上的差异,进而对形成差异的原因进行分析。分析结果表明,两部词典词类标注一致性较高(83.5%完全相同),而存在差异的地方可归结为三类主要原因:词类迁移;词类判断标准不一致;收录义项不同。

Part-of-speech annotation has attracted extensive attention from the areas including Chinese information processing,Chinese grammar study and Chinese lexicographer.Multiple part-of-speech systems have been proposed and there are significant differences between these systems.So far,little research has been done to systematically compare different large-scale part-of-speech annotations.Based on the part-of-speech annotation results in Dictionary of Contemporary Chinese and Grammatical Knowledge-Base Dictionary,this paper proposes a mapping algorithm,which can detect part-of-speech differences in two dictionaries automatically.Further,we analyze the differences and conclude in two perspectives.1）about 83.5% of the part-of-speech annotation results is identical.and 2）all the differences can be attributed to three effects：part-of-speech shifting,different part-of-speech annotation standards and different senses.
