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].
计算机化命题思想密度评估器(CPIDR,发音为“spider”)是一个计算机程序,它基于词性标注自动确定英文文本的命题思想密度(P-密度)。关键思想是命题大致对应于动词、形容词、副词、介词和连词。使用MontyLingua(Liu,2004)对词性进行标注后,CPIDR应用大量规则来调整计数,例如将助动词与主要动词合并。提供了一种“语音模式”,在该模式下CPIDR会排除重复内容和更广泛的填充词。CPIDR是一个用户友好的Windows.NET应用程序,作为开源免费软件根据GPL协议发布。与人工评估者进行测试对比时,它与两位人工评估者的共识的一致性比五位评估者之间的一致性更好[r(80)分别为0.97和r(10)为0.82]。
