Copied to clipboard
| Challenge: | Comparative opinion mining is an important task in opinion mining. |
| Approach: | They propose a task to extract comparative opinion quintuples from product reviews . they propose supplementary annotations and construct three datasets for the task . |
| Outcome: | The proposed method outperforms baseline systems on three datasets and represents a strong benchmark for COQE. |
UniCOQE: Unified Comparative Opinion Quintuple Extraction As A Set (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing methods decompose the COQE task into multiple subtasks and solve them in a pipeline manner, but ignore the intrinsic connection between subtask and the error propagation among stages. |
| Approach: | They propose a unified generative model that solves COQE in one shot by concatenating all the comparative tuples into a target output sequence. |
| Outcome: | The proposed model significantly outperforms the SOTA method on multiple benchmarks and ablation experiments. |
