文本易读性主成分得分 Text Easability Principal Component Scores
Recent work has culminated in the development of the Coh-Metrix Easability components (Graesser, McNamara, & Kulikowich, 2011). These components provide a more complete picture of text ease (and difficulty) that emerge from the linguistic characteristics of texts. The Easability components provided by Coh-Metrix go beyond traditional readability measures by providing metrics of text characteristics on multiple levels of language and discourse. Moreover, they are well-aligned with theories of text and discourse comprehension (e.g., Graesser, Singer, & Trabasso, 1994; Graesser & McNamara, 2011; Kintsch, 1998; McNamara & Magliano, 2009).
最近的工作最终开发出了 Coh-Metrix 易读性组件（Graesser、McNamara & Kulikowich，2011）。这些组件从文本的语言特点出发，更全面地反映了文本的难易程度。Coh-Metrix 提供的易读性要素超越了传统的可读性衡量标准，提供了多层次语言和话语的文本特征度量。此外，它们与文本和话语理解理论非常契合（如 Graesser、Singer 和 Trabasso，1994；Graesser 和 McNamara，2011；Kintsch，1998；McNamara 和 Magliano，2009）。
