| Challenge: | a corpus of 1,043 privacy laws, regulations, and guidelines covers 183 jurisdictions . prior efforts to study privacy law in the form of privacy policies have lacked a large-scale collection . |
| Approach: | They propose a corpus of 1,043 privacy laws, regulations, and guidelines covering 183 jurisdictions. |
| Outcome: | The Privacy Law Corpus covers 1,043 privacy laws, regulations, and guidelines covering 183 jurisdictions. |
Question Answering for Privacy Policies: Combining Computational and Legal Perspectives (D19-1)
Copied to clipboard
| Challenge: | Privacy policies are long and complex documents that are difficult for users to read and understand. |
| Approach: | They present a corpus of 1750 questions about privacy policies of mobile applications and over 3500 expert annotations of relevant answers. |
| Outcome: | The proposed corpus of 1750 questions on privacy policies shows that a strong neural baseline underperforms human performance by almost 0.3 F1 on PrivacyQA. |

| Challenge: | With the introduction of new privacy regulations, disclosures made by the same organization are not always the same in different languages. |
| Approach: | They propose a language annotation scheme to capture nuances of two new privacy regulations, namely the EU’s GDPR and California’s CCPA/CPRA. |
| Outcome: | The proposed method captures the nuances of two new privacy regulations and compares them to a corpus of 64 privacy policies in English and 91 in German with manual annotations for 8K and 19K fine-grained data practices. |
Breaking Down Walls of Text: How Can NLP Benefit Consumer Privacy? (2021.acl-long)
Copied to clipboard
| Challenge: | Privacy policies are long and complex documents that are difficult for users to read and comprehend. |
| Approach: | They propose language technologies to help users reclaim control over their privacy . they highlight many remaining opportunities to develop more precise or nuanced language technologies . |
| Outcome: | The proposed language technologies can address the privacy information gap . they can be more precise or nuanced in the way they use the text of privacy policies. |
Stress Test Evaluation for Natural Language Inference (C18-1)
Copied to clipboard
| Challenge: | Existing models perform well at standard datasets for NLI, achieving impressive results across different genres of text. |
| Approach: | They propose to use automatic stress tests to evaluate models' ability to make inferential decisions. |
| Outcome: | The proposed model performs well across genres of text, but lacks the ability to make inferential decisions. |
Supervised and Unsupervised Methods for Robust Separation of Section Titles and Prose Text in Web Documents (D18-1)
Copied to clipboard
| Challenge: | a web text structure is underutilized, but its visual organization is useful for NLP tasks . a flexible system for extracting hierarchical section titles and prose organization is developed . |
| Approach: | a new system extracts hierarchical section titles and prose organization from web documents . the system uses features from syntax, semantics, discourse and markup to build two models . |
| Outcome: | a new system extracts the hierarchical section titles and prose organization of web documents . the system achieves an overall precision of 0.82 and a recall of 0.98 on three domains of web text . |
