计算机化命题概念密度评定器（CPIDR，发音为“spider”）是一种计算机程序，它能根据词性标注自动确定一篇英语文本的命题概念密度（P - 密度）。其核心思想是命题大致对应动词、形容词、副词、介词和连词。在使用MontyLingua（刘，2004）进行词性标注之后，CPIDR应用大量规则来调整计数，比如将助动词和主要动词合并。它还提供一种“言语模式”，在该模式下CPIDR会排除重复内容以及更多的填充词。CPIDR是一个用户友好的Windows.NET应用程序，作为开源免费软件依据GPL发布。通过与人工评定者进行测试对比，它与两位人工评定者的一致性要优于五位人工评定者彼此之间的一致性[相关系数分别为r(80)=.97对比r(10)=.82]。
The Computerized Propositional Idea Density Rater (CPIDR, pronounced "spider") is a computer program that determines the propositional idea density (P-density) of an English text automatically on the basis of part-of-speech tags. The key idea is that propositions correspond roughly to verbs, adjectives, adverbs, prepositions, and conjunctions. After tagging the parts of speech using MontyLingua (Liu, 2004), CPIDR applies numerous rules to adjust the count, such as combining auxiliary verbs with the main verb. A "speech mode" is provided in which CPIDR rejects repetitions and a wider range of fillers. CPIDR is a user-friendly Windows.NET application distributed as open-source freeware under GPL. Tested against human raters, it agrees with the consensus of two human raters better than the team of five raters agree with each other [r(80) =.97 vs. r(10) =.82, respectively].
