Controllable Fake Document Infilling for Cyber Deception (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing approaches to deter malicious intrusion generate multiple fake versions of a document that are context-agnostic and produce sub-optimal outputs. |
| Approach: | They propose a context-aware model for creating fake documents that masks important concepts of varied lengths and then infills a realistic but fake alternative considering both the previous and future contexts. |
| Outcome: | The proposed model outperforms baseline models in generating highly believable fakes with moderate modification to protect critical information and deceive adversaries. |

| Challenge: | Traditionally, researchers used manual coding to track conflict processes worldwide, but the high costs and slow pace of domain experts make it difficult and costly to monitor complex and rapidly changing conflicts. |
| Approach: | They propose a domain-specific pre-trained language model for conflict and political violence that can be used to train a language model from scratch and continue training. |
| Outcome: | The proposed model outperforms BERT in conflict research. |
Leveraging Codebook Knowledge with NLI and ChatGPT for Zero-Shot Political Relation Classification (2024.acl-long)
Copied to clipboard
| Challenge: | Existing annotation codebook is labor-intensive for coding events from large datasets. |
| Approach: | They propose to use existing annotation codebook to classify political relations without extensive annotations. |
| Outcome: | The proposed methods outperform dictionary-based methods and the existing ontology annotation codebook and improve interpretability and efficiency. |
