# TOFU with author identity names

This is a lossless, order-preserving derivative of the `full` configuration of
[`locuslab/TOFU`](https://huggingface.co/datasets/locuslab/TOFU). It adds one
column, `name`, so that all question-answer pairs about the same fictitious
author can be grouped as one deletion entity.

The source data was pinned at commit
`324592d84ae4f482ac7249b9285c2ecdb53e3a68`. The `question` and `answer`
values and their original order were not changed.

## Loading

```python
from datasets import load_dataset

dataset = load_dataset("ClaudioSavelli/TOFU", "full", split="train")
```

The columns are:

- `question`: the original TOFU question.
- `answer`: the original TOFU answer.
- `name`: the full fictitious-author name assigned to the row.

This repository currently contains only the complete 4,000-row source cohort.
It does not yet define retain, forget, test, or sequential deletion-request
splits.

## Identity construction and validation

The upstream `full` data is ordered as 200 consecutive author blocks, with 20
question-answer pairs per author. Names were recovered from the text within
each block, and block membership was used for rows that refer to the author
only with a pronoun or shortened name.

Validation results:

- 4,000 rows and 200 distinct identity values;
- exactly 20 rows for every identity value;
- 3,969 rows contain their assigned full name verbatim in the question or
  answer;
- 11 rows belonging to named authors omit the full name but are unambiguous
  from their surrounding source block;
- one complete 20-row upstream block never states an author name.

The nameless source block is the Karachi-born Urban Fiction author at
zero-based identity position 88. Its rows are preserved and assigned the
explicit placeholder `__UNKNOWN_TOFU_IDENTITY_088__`. This is deliberately not
a fabricated person name. Consumers should treat the placeholder as one
entity and decide explicitly whether to retain, exclude, or repair that entity
before experiments that require every entity to have a natural-language name.
