Persian RST Corpus

This is the first version of the Persian RST corpus, a corpus of 150 journalistic texts annotated in the framework of Rhetorical Structure Theory [1]. The annotation was mainly based on the English RST Discourse Treebank [2] guideline [3]. The relations used in the corpus are the coarse-grained relations introduced in RST Discourse Treebank tagging guideline, which are Span, Joint, Elaboration, Same-Unit, Contrast, Explanation, Attribution, Cause, Background, Evaluation, Topic, Comment, Condition, Temporal, Summary, Enablement, Comparison, Topic, Change, Manner-Means. We have annotated the corpus using rstWeb [4] and recommend you use this tool if you want to see RST trees graphically. The name of each document contains the source of the news; e.g. etemad001 was taken from Etemad newspaper.

For more information about corpus articles, see the source repository, which provides information about the source, date, author and link of each article. This corpus is published under a CC-BY-NC license.

DISRPT 2023 Shared Task Information

Tokenization, sentence splits, POS tags, morphology and syntactic parses were added using Stanza's default fa model. This dataset contains cases of token that are multi-word contraction. Tokenization reflects those cases by providing the contracted form (with a range of IDs as ID) followed by both of parts of the "extended" form. This was the surprise dataset for DISRPT 2021.

Notes on Segmentation

This dataset contains discontinuous discourse units (split 'same-unit').
