Too much of product information : Don’t worry, let’s look for evidence! (2023.emnlp-industry)
Copied to clipboard
| Challenge: | Existing product question answering models do not provide labelled data for the task and description information for products is very lengthy. |
| Approach: | They propose a distant supervision-based NLI model to prepare training data without manual efforts. |
| Outcome: | The proposed model outperforms standard multi-task fine-tuning and improves 6% in human evaluation over baselines. |

| Challenge: | Identifying granular and actionable topics from customer questions helps improve the overall customer experience. |
| Approach: | They propose a weakly supervised Hierarchical Multi-task Classification Framework to identify granular topics from customer questions . a clustering based taxonomy creation and data labeling module is used to create taxonomies and labelled data with minimal supervision. |
| Outcome: | The proposed model achieves 13% better accuracy over single-task classification frameworks . it can adapt to constantly evolving taxonomy without need of re-training . |
MARS: Multilingual Aspect-centric Review Summarisation (2024.emnlp-industry)
Copied to clipboard
| Challenge: | Existing methods for summarizing customer feedback are not able to extract actionable reviews into a specific target language. |
| Approach: | They propose a framework involving extract-then-summarise to summariser customer feedback into a specific language. |
| Outcome: | The proposed framework improves abstractive baselines and efficiency to real-time systems. |
InsightNet : Structured Insight Mining from Customer Feedback (2023.emnlp-industry)

Sandeep Sricharan Mukku, Manan Soni, Chetan Aggarwal, Jitenkumar Rana, Promod Yenigalla, Rashmi Patange, Shyam Mohan
| Challenge: | Existing methods for extracting structured insights from reviews suffer from drawbacks . lack of structure, non-standard aspect names, lack of abundant training data limit their effectiveness and applicability. |
| Approach: | They propose a semi-supervised multi-level taxonomy from raw customer reviews and a semantic similarity heuristic approach to generate labelled data. |
| Outcome: | The proposed approach outperforms existing methods in structure, hierarchy and completeness. |
