Visualization of Functional-semantic Information: Integrating the Clause and the Discourse

Hengbin Yan, Yinghui Li


In this study, we present our experimental design of an interactive interface that allows users to answer linguistically sophisticated queries utilizing functional-semantic information. Building on previous visualizations of linguistic patterning and discourse structure, the proposed visualization interface presents a unified interface for interrogating the functional-semantic structure of arbitrary texts at different levels of details. To evaluate the effectiveness of the interface, we performed a comparative analysis between visualizations of manual gold-standard annotation and those automatically generated by connecting the interface to existing automatic systems, which revealed remarkable visual correspondence between the two when dealing with small to medium texts. A small-scale case study was then conducted which demonstrated the potential of the resulting tool for effective discovery of interesting patterning in large political texts.
