Revisiting Shallow Discourse Parsing in the PDTB-3: Handling Intra-sentential Implicits

Year: 2021

Type: conference-paper

Abstract: In the PDTB-3, several thousand implicit discourse relations were newly annotated within individual sentences, adding to the over 15,000 implicit relations annotated across adjacent sentences in the PDTB-2.Given that the position of the arguments to these intra-sentential implicits is no longer as well-defined as with inter-sentential implicits, a discourse parser must identify both their location and their sense.That is the focus of the current work.The paper provides a comprehensive analysis of our results, showcasing model performance under different scenarios, pointing out limitations and noting future directions.
