GeoQA: A Geometric Question Answering Benchmark Towards Multimodal Numerical Reasoning (2021.findings-acl)
Copied to clipboard
| Challenge: | Existing methods to solve geometric problems are dependent on handcraft rules and limited on small-scale datasets. |
| Approach: | They propose a Geometric Question Answering dataset with 5,010 geometric problems with corresponding annotated programs to illustrate the solving process. |
| Outcome: | The proposed method is significantly lower than human performance on the proposed dataset than on a publicly available dataset. |
Target-Guided Open-Domain Conversation (P19-1)
Copied to clipboard
| Challenge: | a new study aims to improve opendomain chat systems by integrating goals and strategy into the system. |
| Approach: | They propose a structured approach that introduces coarse-grained keywords to control intended content of system responses and attains smooth conversation transition through turn-level supervised learning. |
| Outcome: | The proposed system produces meaningful and effective conversations significantly better than other approaches. |
How does Misinformation Affect Large Language Model Behaviors and Preferences? (2025.acl-long)
Copied to clipboard
| Challenge: | Existing studies have explored the role of Large Language Models in combating misinformation, but there is still a lack of detailed analysis on the specific aspects and extent to which LLMs are influenced by misinformation. |
| Approach: | They propose to use a benchmark to evaluate LLMs' behavior and knowledge preference toward misinformation to identify their models. |
| Outcome: | The proposed approach is based on 10,346,712 pieces of misinformation and examines knowledge conflicts and stylistic variations. |
Neural-Symbolic Solver for Math Word Problems with Auxiliary Tasks (2021.acl-long)
Copied to clipboard
| Challenge: | Existing solutions for math word problems lack explicit integration of math symbolic constraints, leading to unexplainable and unreasonable predictions. |
| Approach: | They propose a novel mathematical model that explicitly incorporates symbolic constraints by auxiliary tasks to enforce different symbolic reasoning. |
| Outcome: | The proposed solver incorporates symbolic constraints by auxiliary tasks to enforce different symbolic reasoning. |
A Fused Gromov-Wasserstein Framework for Unsupervised Knowledge Graph Entity Alignment (2023.findings-acl)
Copied to clipboard
| Challenge: | Entity alignment is the task of identifying corresponding entities across different knowledge graphs (KGs). |
| Approach: | They propose an unsupervised entity alignment framework that leverages the Fused Gromov-Wasserstein distance to compare KG semantics and KG structural information. |
| Outcome: | The proposed framework surpasses 21 competitive baselines, including cutting-edge methods, without supervision or hyper-parameter tuning. |
