「適性文本閱讀支援系統」之建置與應用研究_團隊計畫

The purpose of this study is to construct the “Readability Evaluation and Analysis of Chinese Text”, REACT. This system is composed of three subsystems as follows. The first subsystem, Text Readability Measuring System, can analyze and produce the text-based features, and label the text grade level. The whole subsystem is composed of a mathematical model and the core measuring tool, called Chinese Readability Index Explore, in which Latent Semantic Analysis is responsible for the extraction of semantic information and the Chinese syntactic parser, developed with the techniques of natural language processing and information engineering, can produce the syntactic features. The language model, which is constructed based on the technologies of information engineering and the theories of computational linguistics, integrates the various text-based features and estimates the grade level of texts. The second subsystem, Text Leveling System, designs a structure, based on the variables relevant to reader-orientation and comprehension. With this structure, this system can produce the grade level of texts as well. The third subsystem, Adaptive Reading Evaluation System works on the evaluation of readers’ reading levels. The outcomes of this subsystem can be further combined with psychological experiments and used as an accuracy checker to compare the estimations of text level produced by the first and second subsystems.
