X-WikiRE: A Large, Multilingual Resource for Relation Extraction as Machine Comprehension (D19-61)
Copied to clipboard
| Challenge: | Existing knowledge bases are heavily biased towards English, but Wikipedias cover very different topics in different languages. |
| Approach: | They propose a multilingual dataset that frams relation extraction as a machine reading problem. |
| Outcome: | The proposed model can be used to transfer models cross-lingually and improves knowledge base completion across languages. |
WikiBank: Using Wikidata to Improve Multilingual Frame-Semantic Parsing (2020.lrec-1)
Copied to clipboard
| Challenge: | Frame-semantic annotations exist for a tiny fraction of the world’s languages, however, Wikidata provides a common, distant supervision signal for semantic parsers. |
| Approach: | They propose a multilingual resource with partial semantic dependency structures that can be used to extend pre-existing resources rather than creating new man-made resources from scratch. |
| Outcome: | The proposed resource can be used to augment pre-existing resources or reduce the annotation effort for low-resource languages. |
