Assessing Text Intelligibility with Discourse Structure

Junyi Jessy Li

PhD Candidate

Department of Computer and Information Science

Abstract

One major aspect of communicating through text is to organize information into an understandable and well-structured discourse. This gives rise to two challenges in text processing: how to understand information organization and how to use such knowledge to characterize text intelligibility. In this talk, I will present two main aspects of my research that tackle these questions. First, I will discuss specificity, i.e., general and specific content in text. I will present an efficient semi-supervised system for predicting sentence specificity, and also talk about the close ties of text specificity to discourse structure and text comprehension. Second, I will discuss information organization factors that impact cross-lingual communication, in particular in the context of Chinese-English translation.
