Towards Reliable and Practical Phishing Detection (2025.naacl-industry)
Copied to clipboard
| Challenge: | Existing datasets lack size and diversity, with only 609 voice phishing samples available in Korean and 638 smishing instances available in English. |
| Approach: | They propose to use a Korean dataset to construct a reliable phishing detection system using language models to evaluate the model's in-domain and unseen attack detection performance. |
| Outcome: | The proposed system performs reasonably well in voice and unseen attacks while smishing detection remains challenging. |
CheckEval: A reliable LLM-as-a-Judge framework for evaluating text generation using checklists (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing evaluation protocols for text generation suffer from rating inconsistencies . lexical overlap-based metrics align poorly with human judgments . |
| Approach: | They propose a checklist-based evaluation framework that improves rating reliability via decomposed binary questions. |
| Outcome: | The proposed framework improves rating reliability by decomposing binary questions . it improves agreement across evaluator models by 0.45 and reduces score variance . human evaluation remains the gold standard, but it #, Equal contribution. |

| Challenge: | a recent study evaluated language models using abstract evaluation criteria that lack the flexibility and granularity of human assessment. |
| Approach: | They propose a benchmark to evaluate nine distinct language models' capabilities . they use instance-specific evaluation criteria to mirror human evaluation . |
| Outcome: | The proposed benchmark evaluates nine distinct capabilities of language models across 77 tasks. |
