Papers with COMBO
COMBO: State-of-the-Art Morphosyntactic Analysis (2021.emnlp-demo)
Copied to clipboard
| Challenge: | COMBO is an end-to-end NLP system for accurate part-of-speech tagging, morphological analysis, and (enhanced) dependency parsing. |
| Approach: | They propose a fully neural NLP system for accurate part-of-speech tagging, morphological analysis, lemmatisation, and (enhanced) dependency parsing. |
| Outcome: | The proposed system predicts categorical morphosyntactic features whilst also exposes their vector representations, extracted from hidden layers. |
COMBO: A Complete Benchmark for Open KG Canonicalization (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing datasets for open KG canonicalization only provide gold entity-level canonization for noun phrases. |
| Approach: | They propose a complete benchmark for open KG canonicalization that provides gold ontology-level canonization for relation phrases and source sentences for extraction. |
| Outcome: | The proposed method improves relation canonicalization and ontology-level canonization of the noun phrase. |
Merging Generated and Retrieved Knowledge for Open-Domain QA (2023.emnlp-main)
Copied to clipboard
| Challenge: | Open-domain question answering systems often have retrieval modules but retrieving passages from external knowledge sources is known to suffer from insufficient knowledge coverage. |
| Approach: | They propose a Compatibility-Oriented knowledge Merging framework to leverage both sources of information by matching LLM-generated passages with retrieved counterparts into compatible pairs. |
| Outcome: | The proposed framework outperforms baselines on three out of four tested open-domain QA benchmarks. |
