模糊限制语用于表示不确定性的观点。由模糊限制语所引导的信息为模糊限制信息,开展中文模糊限制信息检测研究,对事实信息抽取意义重大。模糊限制信息检测包含模糊限制性句子识别和模糊限制信息范围检测两个子任务。中文模糊限制信息范围语料库的缺乏,影响了中文模糊限制信息检测的研究。该文研究制定了基于短语结构的中文模糊限制信息范围标注规则,构建了中文模糊限制信息范围语料库。最后对标注的语料库进行了统计和分析。该文语料库的构建为中文模糊限制信息检测研究提供了资源支持。
Abstract
Hedge is usually used to express uncertainty. Hedge information indicates that authors do not backup their statements with facts. Chinese hedge information detection is of great significance for Chinese factual information extraction. Hedge information detection contains two subtasks: identifying hedges and detecting the in-sentence scopes of hedge cues. The lack of Chinese hedge scope corpus has limited the research of Chinese hedge scope information detection. This paper first manually crafted the syntactic rules for Chinese hedge scope annotation, and then constructs a Chinese hedge scope corpus. Finally, we statistically analyzed the corpus. The construction of the corpus provides a great support for Chinese uncertainty detection.
