This paper presents the Virginia Tech system that participated in the CoNLL-2016 shared task on shallow discourse parsing.We describe our end-to-end discourse parser that builds on the methods shown to be successful in previous work.The system consists of several components, such that each module performs a specific subtask, and the components are organized in a pipeline fashion.We also present our efforts to improve several componentsexplicit sense classification and argument boundary identification for explicit and implicit arguments -and present evaluation results.In the closed evaluation, our system obtained an F1 score of 20.27% on the blind test.
