| ### 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](https://github.com/amir-zeldes/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. | |

| ## 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'). | |
