Benchmarking and Building Zero-Shot Hindi Retrieval Model with Hindi-BEIR and NLLB-E5 (2025.naacl-long)
Copied to clipboard
| Challenge: | Existing benchmarks for evaluating retrieval models in Hindi are lacking . despite efforts to build multilingual retrieval systems, this is still a work in progress . |
| Approach: | They evaluate Hindi retrieval models on the Hindi-BEIR benchmark and introduce a multilingual model that leverages a zero-shot approach to support Hindi without the need for Hindi training data. |
| Outcome: | The proposed model leverages a zero-shot approach to support Hindi without the need for Hindi training data. |
M3Retrieve: Benchmarking Multimodal Retrieval for Medicine (2025.emnlp-main)
Copied to clipboard
| Challenge: | Strong retrieval models are increasingly important in knowledge-intensive domains. |
| Approach: | They propose a benchmark to evaluate multimodal retrieval models in medical settings . they examine 1.2 million text documents and 164K multimodal queries . |
| Outcome: | The proposed model spans 5 domains,16 medical fields, and 4 distinct tasks with over 1.2 Million text documents and 164K multimodal queries. |
Do Language Models Have a Common Sense regarding Time? Revisiting Temporal Commonsense Reasoning in the Era of Large Language Models (2023.emnlp-main)
Copied to clipboard
| Challenge: | Temporal reasoning is a vital component of human communication and understanding, yet remains an underexplored area within the context of Large Language Models (LLMs). |
| Approach: | They propose to use 3 prompting strategies to evaluate 8 different LLMs across 6 datasets and 2 Code Generation LMs to perform the analysis. |
| Outcome: | The proposed models perform better on NLP tasks than the standard models on the same dataset. |
HealthAlignSumm : Utilizing Alignment for Multimodal Summarization of Code-Mixed Healthcare Dialogues (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Collaboration between doctors and AI scientists is leading to personalized models to stream-line healthcare tasks and improve productivity. |
| Approach: | They propose to use alignment techniques to combine a doctor-patient dialogue with a visual component of the BART model. |
| Outcome: | The proposed model in-tegrates visual components with the BART ar-chitecture. |
