Abstract

This research examines how subjective evaluations of persuasive texts are influenced by relations between sentences. Furthermore, an analysis technique known as Latent Semantic Analysis (LSA) is applied to persuasive texts to produce evaluations which are compared against human evaluations. The authors prepared two varieties of texts for evaluation based on coherent texts, surface-change texts (those which the frequency of key words and length of key sentences was modified) and composition-change texts (those in which the composition of the text was modified, for example rearranging paragraphs). After evaluation, it was found that the evaluators reading skills and composition of the test influence the subjective evaluation of persuasive texts. In addition to this, it was found that LSA was not useful for the evaluation of persuasive texts.
