 # MemoryCD
 
-A filtered cross-domain subset of the Amazon Reviews 2023 dataset, prepared
-for memory-augmented LLM evaluation on four recommendation tasks:
-rating prediction, sequential recommendation, explanation generation, and
-review generation.
+Filtered cross-domain subset of Amazon Reviews 2023 for memory-augmented LLM
+evaluation. All configs expose a single `test` split (evaluation only).
 
 ## Contents
 
-| Config | File | Records | Description |
-|---|---|---:|---|
-| `users_interactions` | `users/cross_domain_users_sampled.jsonl.gz` | 323 | Users with interactions across all four domains below. |
-| `meta_personal_care`  | `meta/Beauty_and_Personal_Care.jsonl.gz` | 33,475 | Item metadata. |
-| `meta_books`          | `meta/Books.jsonl.gz` | 48,054 | Item metadata. |
-| `meta_electronics`    | `meta/Electronics.jsonl.gz` | 25,441 | Item metadata. |
-| `meta_home`           | `meta/Home_and_Kitchen.jsonl.gz` | 60,900 | Item metadata. |

-The meta files contain **exactly the items referenced by the 323 users**
-(167,870 unique `parent_asin` values), filtered from the original
-~36 M-item Amazon Reviews 2023 meta files (100% coverage).
