| ## Data Components |
|
|
| ### `data/` |
|
|
| The `data/` directory provides JSONL versions of the main dataset components for convenient loading and processing. |
|
|
| - `ground_truth.jsonl` contains the ground-truth personalization information for all tasks. |
| - `query_personalization_0.jsonl` contains Level 0 queries, where both website and preference constraints are explicit. |
| - `query_personalization_1.jsonl` contains Level 1 queries, where preference constraints are explicit while website information is masked. |
| - `query_personalization_2.jsonl` contains Level 2 queries, where both website and preference constraints are masked. |
| - `user_history.jsonl` contains user histories that reveal preferences implicitly through behavioral patterns. |
|
|
| ### `ground_truth/` |
| |
| The `ground_truth/` directory contains 150 individual JSON files, one for each Persona2Web task. Each file provides the reference information used to evaluate whether the agent correctly resolves the personalized query. |
|
|
| ### `query/` |
|
|
| The `query/` directory contains task queries organized by ambiguity level. |
|
|
| - `personalization_0/` contains 150 clear queries with explicit website and preference constraints. |
| - `personalization_1/` contains 150 queries where the website is masked and must be inferred from user history. |
| - `personalization_2/` contains 150 fully ambiguous queries where both website and preference constraints must be inferred from user history. |
|
|
| ### `user_history/` |
| |
| The `user_history/` directory contains 50 JSON files of browsing-style user histories. These histories provide contextual user behavior over long time spans, where preferences are embedded implicitly rather than stated as explicit profile descriptions. |
