NTU End-to-End Chinese Discourse Parser


This page introduces an end-to-end Chinese discourse parser. The parser based on a unified framework by using recursive neural network (RvNN) to jointly model the subtasks including elementary discourse unit (EDU) segmentation, tree structure construction, center labeling, and sense labeling. To the best of our knowledge, this is the first open source toolkit for Chinese discourse parsing. We release the source code with a pre-trained model for the NLP community. The standalone toolkit can be integrated into subsequent applications without the need of external resources such as syntactic parser.


Follow the manual provided with the github package.


The input is a paragraph in Simplified Chinese. For example:

The output contains the EDU numbering and the discourse parsing tree constructing from the EDUs, associated with corresponding relation sense and centering:
