摘要
使用计算机自动文本分析来考察老年人话语产出特征,是智能技术在老年语言学领域中应用的一个重要实例。Coh-Metrix和LIWC是国内外最常用的两种自动文本分析工具,在国外老年语言学研究中已被广泛使用。前者及其衍生工具侧重语篇分析,从语篇结构特征评估老年人群的话语连贯性、衔接性;后者侧重从词汇入手进行语言心理特征测量,考察老年人的思维方式、内心状态及人格特征。两种工具对老年失智症等疾病的早期诊断和评估具有重要临床意义。未来研究应关注自动化转录和切分的可行性,利用此类工具对失智症患者进行长期追踪研究以提高病程判断的精准度,进一步评估此类方法能否在临床上检测老年人认知水平的变化过程。我国应加快建设老年人话语语料库,同时开展针对汉语自动文本分析工具的开发。
The use of computer automatic text analysis in the study of the elders’discourse is an essential application of artifi-cial intelligence in the fi eld of Gerontolinguisitcs.Coh-Metrix and LIWC are two most commonly-used automatic text analysis tools,which have been widely used in the study of Gerontolinguistics abroad.Coh-Metrix evaluates the coherence and cohesion of the elders’discourse from the perspective of discourse structure features.LIWC mainly measures the elders’vocabulary to investigate their thinking mode,inner state,and personality characteristics.Both tools demonstrate the feasibility of computer-automated text analysis for early diagnosis of dementia with important clinical implications.Future research can focus on the automatic transcription and segmentation,conducting long-term follow-up research on dementia patients to improve the ac-curacy of diagnosis and early detection of cognitive function changes in clinical trials.This paper also suggests to speed up the construction of a Chinese elders’discourse-tagged corpus and develop automatic text analysis tools for the Chinese language.
