| Challenge: | Recent theoretical work argues that any watermark can be erased via random walk attacks that perturb text while preserving quality. |
| Approach: | They propose that any watermark can be erased via random walk attacks that perturb text while preserving quality. |
| Outcome: | The proposed method underperforms the theoretical models in large-scale experiments and human-validated assessments. |
Generate-then-Retrieve: Intent-Aware FAQ Retrieval in Product Search (2023.acl-industry)
Copied to clipboard
| Challenge: | Frequently Asked Question (FAQ) retrieval aims at retrieving question-answer pairs for a given user query. |
| Approach: | They propose to use an intent classifier to predict whether a query is looking for an FAQ and a reformulation model to rewrite the query into a natural question to improve retrieval performance. |
| Outcome: | The proposed method improves 12% on Hit@1 on retrieving ground-truth FAQs while reducing latency by 95% compared to baseline systems. |
