Summary/Abstract: The aim of this research is to provide an overview of how Rhetorical Structure Theory can be used to identify important information in texts and summarization. 204 undergraduate students and 2 domain experts participated in the research. In order to collect data in the research, an informative text was divided into units according to the Rhetorical Structure Theory. Undergraduate students were asked to rate these units according to their level of importance to the text, and field experts were asked to determine the role of units. Krippendorff's Alpha, Kappa, Pearson correlation analysis and descriptive statistics were carried out on the data obtained. According to the results of the research, there is a moderate agreement between experts are in determining the units in the text. Students are intuitively aware of the nucleus and satellite distinction revealed by the rhetorical structure theory. According to the results of the research, the contributions of the Rhetorical Structure Theory in determining important information in informative texts and summarizing are limited. It is anticipated that better results can be obtained in determining the important information in the informative texts and summarizing the texts along with the other theories.
