Hi everyone,
The Georgetown University Corpling Lab https://gucorpling.org/corpling/ is pleased to announce the release of DiscoExplorer, a publicly available open source search engine for discourse relation data:
https://gucorpling.org/discoexplorer/
DiscoExplorer indexes all 38 discourse relation datasets from the DISRPT shared task on discourse relation classification, covering 16 languages in 6 frameworks (RST/eRST, PDTB, SDRT, ISO and dependencies) with over 300K relations and 5M tokens, all using a uniform label set. The interface allows searching by relation for tokens and UD annotations such as POS tags, lemmas and dependency functions, as well as offering quantitative breakdowns and dataset distribution comparisons.
For more information, check out this paper https://arxiv.org/abs/2605.15304 , which will be presented as a demo at the CODI-CRAC workshop https://sites.google.com/view/codi-crac2026/ at ACL in San Diego.
We hope this will be useful and look forward to your feedback!
Best wishes,
Amir
