# Introduction |
|
|
|
Anki Revlogs 10K is a dataset of 10k collections from Anki for FSRS project. It is a random sample of collections with 5000+ revlog entries, so it should contain a mix of older (still active) users, and newer users. |
|
|
|
The dataset contains three parts: revlogs, cards, and decks. |
|
|
|
## Revlogs |
|
|
|
This dataset contains flashcard review records with the following fields: |
|
|
|
- **card_id**: Unique identifier for each flashcard |
|
- **day_offset**: Number of days since the start of user's first review |
|
- **rating**: User's rating of their recall performance (1: again, 2: hard, 3: good, 4: easy) |
|
- **state**: Card's learning state (0: new, 1: learning, 2: review, 3: relearning) |
|
- **duration**: Time spent on the card review in milliseconds (range: 0-60000) |
|
- **elapsed_days**: Days since the last review (-1 for new cards) |
|
- **elapsed_seconds**: Seconds since the last review (-1 for new cards) |
|
|
|
The records have been pre-sorted in chronological order. |
|
|
|
## Cards |
|
|
|
This dataset contains card-note-deck relationship mappings with the following fields: |
|
|
|
- **card_id**: Unique identifier for each flashcard |
|
- **note_id**: Unique identifier for each note, where a note can contain multiple cards |
|
- **deck_id**: Unique identifier for each deck, representing different study categories or subjects |
|
|
|
## Decks |
|
|
|
This dataset contains deck hierarchy information with the following fields: |
|
|
|
- **deck_id**: Unique identifier for each deck |
|
- **parent_id**: ID of the parent deck, indicating the deck's position in the hierarchy |
|
- **preset_id**: ID of the preset configuration applied to the deck |
