| Challenge: | Existing EE datasets define fixed event types and design specific schemas for each of them, failing to cover diverse events emerging from the online text. |
| Approach: | They propose to use a sentence-level dataset to benchmark Open Event Extraction without restricting event types. |
| Outcome: | The proposed dataset contains more than 42,000 news titles in 34 topics collected from Chinese web pages. |
LeLoRA: Learnable Low-Rank Adaptation of Large Language Models (2026.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to fine-tuning large language models (LLMs) rely on manually specified and fixed hyperparameters, resulting in suboptimal performance and low parameter efficiency. |
| Approach: | They propose a framework that allows for dynamically learned adaptive adaptation strategies to be used to fine-tune large language models. |
| Outcome: | The proposed framework outperforms baselines in adapting large language models. |
Enhancing In-Context Learning via Implicit Demonstration Augmentation (2024.acl-long)
Copied to clipboard
| Challenge: | In-context learning (ICL) is a new paradigm for pre-trained language models that can make predictions for unseen inputs without updating parameters. |
| Approach: | They propose a method that enables a model to augmented copies of a demonstration by leveraging their deep feature distribution and a logit calibration mechanism. |
| Outcome: | The proposed method significantly improves the average and worst-case accuracy across diverse PLMs and tasks. |
Event-enhanced Retrieval in Real-time Search (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing embedding-based retrieval models face the "semantic drift" problem . a low adoption rate of retrieval results is evident in real-time search scenarios . |
| Approach: | They propose an embedding-based retrieval approach that enhances real-time retrieval performance by adding contrastive learning to the dual-encoder model. |
| Outcome: | The proposed approach improves the dual-encoder model of traditional EBR. |
Event-Centric Query Expansion in Web Search (2023.acl-industry)
Copied to clipboard
| Challenge: | Existing studies rely on long-term search log mining to improve search experience . EQE system is a novel event retrieval framework that can select the best expansion from a significant amount of potential events quickly and accurately. |
| Approach: | They propose a QE system that uses a four-stage event retrieval framework . they collect news headlines and then refine a dual-tower semantic model to serve as an encoder . |
| Outcome: | The proposed system can select the best expansion from a significant amount of potential events quickly and accurately. |
