What is Your Article Based On? Inferring Fine-grained Provenance (2021.acl-long)
Copied to clipboard
| Challenge: | a new study of claim provenance seeks to trace and explain the origins of claims . a critical reader must be able to assess where the information comes from and where it originates from . |
| Approach: | They propose a method to model and reason about the provenance of multiple interacting claims . they propose generating metadata for the source article based on context and search signals . |
| Outcome: | The proposed method improves on baselines by identifying key external information in the source article. |
Evidence-based Trustworthiness (P19-1)
Copied to clipboard
| Challenge: | Existing methods to estimate the trustworthiness of information sources are local in that they apply to a given claim. |
| Approach: | They propose a framework for estimating the trustworthiness of information sources in an environment where multiple sources provide claims and supporting evidence. |
| Outcome: | The proposed models show that they improve on baselines and show that the proposed models are more accurate than baselines. |
“Who said it, and Why?” Provenance for Natural Language Claims (2020.acl-main)
Copied to clipboard
| Challenge: | generating and publishing content is so easy, we are bombarded with information and are exposed to all kinds of claims. |
| Approach: | They propose a formal definition of provenance graph for a given natural language claim . they evaluate the approach using two benchmark datasets to capture provenance . |
| Outcome: | The proposed method shows initial success in capturing provenance and its effectiveness on claim verification. |
