QualiText
QualiText is a balanced English text-classification dataset for studying text
origin and text quality. Each example contains a text field and a label
field. The dataset has five labels with the same number of examples in each
class.
Labels
| Label | Description |
|---|---|
human |
Human-authored text from Wikipedia and 4chan. |
machine_generated |
Machine-generated text from the Qwen3.8-Max, GLM-5.2, and Kimi-K3 distillation corpus. |
corrupted |
Wikipedia text modified with deterministic word deletions, swaps, duplications, or typo-like edits. |
marketing |
Marketing-oriented text from FineWeb-Marketing. |
low_quality |
Spam, ham/phishing-email corpus examples, and synthetic text created by removing punctuation, lowercasing, and shuffling words. |

Data Format
text: string
label: ClassLabel or string
Example:
{
"text": "Example document text.",
"label": "human"
}
Intended Uses
QualiText can be used for:
- Training baseline text-origin classifiers
- Evaluating robustness to common text corruption
- Comparing text-quality classification strategies
- Prototyping data filtering and moderation models
It should not be used as the sole basis for deciding whether a person used an AI system or whether content is trustworthy.
Limitations and Biases
- The labels represent dataset provenance and synthetic transformations, not definitive proof of authorship.
- The human class contains platform-specific and encyclopedic writing styles.
- The marketing and low-quality classes may contain strong lexical shortcuts.
- Synthetic corruption does not represent every real-world form of corruption.
- The machine-generated class may reflect the style and artifacts of its teacher models and prompts.
- Source datasets may contain offensive, private, copyrighted, or otherwise sensitive material. Review examples before deployment.
- Performance may not generalize to languages, domains, or writing styles not represented in the sources.
Licensing
QualiText is an aggregated dataset. The applicable license and usage terms of each source dataset may differ and continue to apply to the corresponding examples.
