Can Large Language Models be Effective Online Opinion Miners? (2025.emnlp-main)
Copied to clipboard
| Challenge: | OOMB is a novel benchmark designed to assess the ability of large language models (LLMs) to extract and analyze opinions from diverse and complex online environments. |
| Approach: | They propose an online opinion mining benchmark to assess the ability of large language models to extract and analyze opinions from diverse online environments. |
| Outcome: | The proposed benchmark assesses the ability of large language models to mine opinions effectively from diverse and complex online environments. |
Self-Consistent Reasoning-based Aspect-Sentiment Quad Prediction with Extract-Then-Assign Strategy (2024.findings-acl)
Copied to clipboard
| Challenge: | Recent studies have developed powerful generative methods for aspect sentiment quad prediction (ASQP) but they still suffer from imprecise predictions and limited interpretability due to data scarcity and inadequate modeling of the quadruplet composition process. |
| Approach: | They propose a self-consistent reasoning-based aspect sentiment quadruple prediction framework which generates reasonings and corresponding quadruples in sequence. |
| Outcome: | The proposed model significantly improves its ability to handle complex reasoning tasks and correctly predict quadruplets through consistency voting, resulting in enhanced interpretability and accuracy in aspect sentiment quadr uplp prediction. |
Make Compound Sentences Simple to Analyze: Learning to Split Sentences for Aspect-based Sentiment Analysis (2024.findings-emnlp)
Copied to clipboard
| Challenge: | generative methods have shown promising results for extracting sentiment quadruplets . compound sentences can contain multiple quadroutlets, making extraction difficult . |
| Approach: | They propose an Aspect Term Oriented Sentence Splitter which simplifies compound sentences into simpler and clearer forms. |
| Outcome: | The proposed method outperforms existing methods in ASQP and ACOS tasks. |
Why These Documents? Explainable Generative Retrieval with Hierarchical Category Paths (2026.findings-acl)
Copied to clipboard
| Challenge: | Generative retrieval directly decodes a document identifier, making it impossible to provide explanations for its retrieval decision. |
| Approach: | They propose a hierarchical category path-Enhanced Generative Retrieval that generates category paths step-by-step and decodes docid. |
| Outcome: | The proposed method provides explanations for retrieval decision by generating hierarchical category paths step-by-step and decoding docid. |
