# Third-party notices

This file documents source-specific terms and the scope of the FACTPROP
dataset license. It is informational and does not replace the applicable
licenses or legal terms.

## Wikidata

FACTPROP uses Wikidata API and SPARQL results for entity resolution and
factual-relation validation. Wikidata structured data is dedicated to the
public domain under the
[CC0 1.0 Universal Public Domain Dedication](https://creativecommons.org/publicdomain/zero/1.0/).
Wikidata QIDs and facts remain subject to those terms. Their inclusion does
not imply endorsement by Wikidata or the Wikimedia Foundation.

## Wikipedia references

Some generated evidence rationales refer to Wikipedia as a general source,
and project documentation describes the graph candidates as
Wikipedia-derived. The released graph-building code does not contain a
Wikipedia page-content ingestion path; `surface`, `question`, and
`evidence_rationale` are requested as generated fields in the construction
prompt. The release does not intentionally redistribute Wikipedia article
text.

Wikipedia text, if independently accessed or incorporated by a downstream
user, is generally available under
[CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/) and may also
be subject to additional terms described by Wikimedia. The FACTPROP
CC BY 4.0 grant does not relicense Wikipedia content.

## Model-generated fields

The released construction code identifies `gpt-4o-mini` as the default model
used to generate candidate triplets and natural-language fields. OpenAI's
applicable terms state that, as between the customer and OpenAI and to the
extent permitted by law, the customer owns Output and OpenAI assigns any
right, title, and interest it may have in that Output to the customer:

- [OpenAI Services Agreement](https://openai.com/policies/services-agreement/)
- [OpenAI Terms of Use](https://openai.com/policies/row-terms-of-use/)

Model output may not be unique and can contain errors or material similar to
third-party content. The FACTPROP license applies only to rights the authors
are authorized to license and does not guarantee that every generated string
is independently protectable or free of third-party claims.

## No endorsement

References to organizations, people, datasets, models, or services are for
provenance and research documentation only. They do not imply sponsorship,
endorsement, or affiliation.
