Transition-based Directed Graph Construction for Emotion-Cause Pair Extraction (2020.acl-main)
Copied to clipboard
| Challenge: | Existing methods to extract emotions and causes from unannotated text are pipelined, causing error propagation. |
| Approach: | They propose to transform a task into a procedure of parsing-like directed graph construction . they propose to generate a directed graph with labeled edges based on a sequence of actions . |
| Outcome: | The proposed method outperforms the state-of-the-art methods by 6.71% (p0.01) in F1 measure. |

| Challenge: | Large language models (LLMs) produce natural language explanations, but they lack faithfulness and do not reflect the evidence the model uses to decide. |
| Approach: | They propose a model-agnostic framework that evaluates and improves the faithfulness of LLM explanations without token masking or task-specific heuristics. |
| Outcome: | The proposed framework improves faithfulness of large language models without masking or heuristics. |
An Empirical Study on Multiple Information Sources for Zero-Shot Fine-Grained Entity Typing (2021.emnlp-main)
Copied to clipboard
| Challenge: | Auxiliary information from multiple sources has been demonstrated to be effective in zero-shot fine-grained entity typing (ZFET) however, there is no comprehensive understanding of how to make better use of the existing information sources and how they affect the performance of ZFET. |
| Approach: | They propose a multi-source fusion model targeting auxiliary information from multiple sources to improve zero-shot fine-grained entity typing (ZFET) |
| Outcome: | The proposed model achieves 11.42% and 22.84% gains over state-of-the-art baselines on BBN and Wiki respectively with regard to macro F1 scores. |
Masked Language Models Know Which are Popular: A Simple Ranking Strategy for Commonsense Question Answering (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Empirical results show that pre-trained language models can improve the typical answer generation of GLMs. |
| Approach: | They propose a ranking strategy that exploits WordNet to train a ranker that picks out the most popular answers for commonsense questions. |
| Outcome: | The proposed ranking strategy is tested on a commonsense question answering (QA) dataset and on negative samples from WordNet. |
Instruct-of-Reflection: Enhancing Large Language Models Iterative Reflection Capabilities via Dynamic-Meta Instruction (2025.naacl-long)
Copied to clipboard
| Challenge: | Existing approaches involve models iterating and improving their previous responses based on internal reflection ability or external feedback. |
| Approach: | They propose a reflection framework that leverages meta-thoughts and self-consistency to enhance the iterative reflection capability of Large LanguageModels. |
| Outcome: | The proposed framework achieves an average improvement of 10.1% over established baselines in mathematical and commonsense reasoning tasks, highlighting its efficacy and applicability. |
A Knowledge Regularized Hierarchical Approach for Emotion Cause Analysis (D19-1)
Copied to clipboard
| Challenge: | Emotion cause analysis aims to identify the reasons behind emotions . previous models focus on learning architecture with local textual information . |
| Approach: | They propose a method to extract emotion cause with hierarchical neural model and knowledge-based regularizations by sentiment lexicon and common knowledge. |
| Outcome: | The proposed method outperforms baselines on two public datasets in different languages and outperformed competitive baselines by 2.08%. |
Emotion-Cause Pair Extraction as Sequence Labeling Based on A Novel Tagging Scheme (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to extract emotions and causes from unannotated emotion texts are labor intensive and limited applications in real-world scenarios. |
| Approach: | They propose a novel task to find emotions and corresponding causes in unannotated emotion texts. |
| Outcome: | The proposed model outperforms the state-of-the-art method by 2.26% (p0.001) in F1 measure. |
A Neural Transition-based Model for Argumentation Mining (2021.acl-long)
Copied to clipboard
| Challenge: | Existing methods for identifying argumentation structures are inefficient and class imbalanced. |
| Approach: | They propose a neural transition-based model that incrementally builds an argumentation graph by generating a sequence of actions. |
| Outcome: | The proposed model can handle tree and non-tree structured argumentation without structural constraints. |
