RetinaQA: A Robust Knowledge Base Question Answering Model for both Answerable and Unanswerable Questions (2024.acl-long)
Copied to clipboard
| Challenge: | Existing knowledge base question answering models assume all questions to be answerable. |
| Approach: | They propose a new KBQA model that unifies two key ideas in a single architecture . they propose logical form discrimination and sketch-filling-based construction for unanswerable questions . |
| Outcome: | The proposed model outperforms existing models in handling answerable and unanswerable questions. |
Few-shot Transfer Learning for Knowledge Base Question Answering: Fusing Supervised Models with In-Context Learning (2024.acl-long)
Copied to clipboard
| Challenge: | Existing Knowledge Base Question Answering (KBQA) architectures are expensive and time-consuming to deploy. |
| Approach: | They propose a KBQA architecture that performs KB-retrieval using multiple source-trained retrievers and re-ranks using an LLM. |
| Outcome: | The proposed architecture outperforms adaptations of SoTA KBQA models when training data is limited. |
Synergizing In-context Learning with Hints for End-to-end Task-oriented Dialog Systems (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing end-to-end task-oriented dialogue systems require extensive training datasets to perform well. |
| Approach: | They propose a system that synergizes LLMs with task-specific hints to improve alignment in low-data settings. |
| Outcome: | The proposed model improves alignment in low-data settings while retaining competitive performance in full-data environments. |
DynaSemble: Dynamic Ensembling of Textual and Structure-Based Models for Knowledge Graph Completion (2024.acl-short)
Copied to clipboard
| Challenge: | Existing approaches to Knowledge Graph Completion use textual descriptions of the KG entities and relations to perform the task. |
| Approach: | They propose a method to combine two popular approaches to Knowledge Graph Completion . structure-based models perform better when gold answer is easily reachable . textual models exploit textual descriptions to give good performance . |
| Outcome: | The proposed method achieves 6.8 pt MRR and 8.3 pTits@1 gains over the best baseline model for WN18RR dataset. |
SSP: Self-Supervised Prompting for Cross-Lingual Transfer to Low-Resource Languages using Large Language Models (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Recent studies have shown that very large language models (LLMs) can perform NLP tasks with just in-context learning (ICL) but their utility in other languages is underexplored. |
| Approach: | They propose a novel approach to in-context learning that uses noisy test data to generate more accurate labels for LLMs. |
| Outcome: | Experiments on three tasks and eleven LLMs show that the proposed approach outperforms existing in-context learning baselines on English NLP and reasoning tasks. |
MediTOD: An English Dialogue Dataset for Medical History Taking with Comprehensive Annotations (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing datasets lacking comprehensive annotations for medical history-taking are non-English . existing datasets lack comprehensive annotation for medical slots and their attributes . |
| Approach: | They propose a dataset of doctor-patient dialogues in English for medical history-taking task. |
| Outcome: | The proposed datasets are available in English and are compared with existing datasets. |
