A New Task and Dataset on Detecting Attacks on Human Rights Defenders

1 code implementation30 Jun 2023 Shihao Ran, Di Lu, Joel Tetreault, Aoife Cahill, Alejandro Jaimes

The ability to conduct retrospective analyses of attacks on human rights defenders over time and by location is important for humanitarian organizations to better understand historical or ongoing human rights violations and thus better manage the global impact of such events.

Platforms for Non-speakers Annotating Names in Any Language

no code implementations ACL 2018 Ying Lin, Cash Costello, Boliang Zhang, Di Lu, Heng Ji, James Mayfield, Paul McNamee

We demonstrate two annotation platforms that allow an English speaker to annotate names for any language without knowing the language.

ELISA-EDL: A Cross-lingual Entity Extraction, Linking and Localization System

no code implementations NAACL 2018 Boliang Zhang, Ying Lin, Xiaoman Pan, Di Lu, Jonathan May, Kevin Knight, Heng Ji

We demonstrate ELISA-EDL, a state-of-the-art re-trainable system to extract entity mentions from low-resource languages, link them to external English knowledge bases, and visualize locations related to disaster topics on a world heatmap.
