|
| ## What this is |
|
|
| The graph served by the SPARQL endpoint at |
| [gptkb.org/query](https://gptkb.org/query/). Entities, predicates and |
| concepts are ID-based IRIs: |
|
|
| ``` |
| <https://gptkb.org/entity/E0> a person, place, work, … |
| <https://gptkb.org/prop/P0> a predicate |
| <https://gptkb.org/concept/C0> a class |
| ``` |
|
|
| The vocabulary is deliberately three predicates and no more: |
|
|
| | Predicate | Meaning | |
| | --- | --- | |
| | `<https://gptkb.org/prop/P…>` | a disambiguated fact | |
| | `rdfs:label` | the canonical name of an entity, predicate or concept | |
| | `skos:altLabel` | **every surface form** observed for an entity | |
|
|
| Literals are plain RDF strings — typed literals (`xsd:date`, |
| `xsd:integer`) are deferred. Concepts carry no `rdfs:subClassOf`: the |
| source has no hierarchy to export. |
|
|
| ## What this is not |
|
|
| It is not the whole of v2, and the gap is the point of the project. |
|
|
| A fact in GPTKB v2 has **six** terms, not three: alongside the |
| disambiguated subject, predicate and object, it records the *wording* |
| each was stated with, and the provenance of how that wording was |
| resolved. A triple has nowhere to put either. |
|
|
| The surface forms survive here — they are attached to the entity as |
| `skos:altLabel`, so `E14` (United States of America) carries 127 of |
| them: `US`, `U.S.A.`, `America`, `Estados Unidos de América`, and so on. |
| What does not survive is **which form was used on which fact**. You can |
| see the loss directly: `<E0> <P0> <C0>` appears five times in the file, |
| because five differently worded facts about Vannevar Bush resolve to |
| it, and RDF set semantics keep one. That collapse is the entire |
| difference between this file's 33,364,378 lines and the 32,794,801 |
| triples a store loads from it. |
|
|
| Provenance is absent outright — no batch identifiers, no pipeline |
| status, no object descriptions. |
|
|
| A release carrying the full six-term record is in preparation. Until |
| then, every [entity](https://gptkb.org/browse/) and triple page on |
| gptkb.org shows it. |
|
|
| ## Loading |
|
|
| ```bash |
| # Virtuoso, QLever, Jena, rdflib — anything that reads N-Triples |
| gunzip -c gptkb_v2.0_rdf.nt.gz | head |
| ``` |
|
|
| Load into a named graph of `<https://gptkb.org/gptkb>` to match the IRIs |
| the file already carries. |
|
|
| ## Earlier versions |
|
|
| The v1 line is archived separately and stays downloadable permanently: |
| [GPTKB_v1.5](https://huggingface.co/datasets/Knowledge-aware-AI/GPTKB_v1.5) |
| and [GPTKB_v1](https://huggingface.co/datasets/Knowledge-aware-AI/GPTKB_v1). |
| Note that v1 used label-based IRIs (`/entity/Vannevar_Bush`) where v2 |
| uses ID-based ones (`/entity/E0`); the two are not interchangeable. |
|
|
| ## Citation |
|
|
| A paper describing GPTKB v2 is in preparation. Please check |
| [gptkb.org/publications](https://gptkb.org/publications/) for the |
