# YAGO 4.5 Dataset (English subset for LLM fine-tuning) |
|
|
|
## Dataset Description |
|
This datasets contains triples filtered from yago-facts.ttl and |
|
yago-beyond-wikipedia.ttl in the YAGO 4.5 dataset. The SPARQL query |
|
used to filter the triples is in `raw/filter.sparql`. This represents |
|
a subset of the YAGO 4.5 dataset maintaining only English labels. |
|
|
|
I remapped some schema.org URIs to use the |
|
`http://yago-knowledge.org/resource/` which were not present in the |
|
schema.org vocabulary. I also removed schema:sameAs and owl:sameAs |
|
relations from this dataset, as well as triples with xsd:anyURI object |
|
literals, as my goal is to use this dataset for fine-tuning a large |
|
language model for knowledge graph completion and I do not want |
|
to train the base model to predict these kind of relations. |
|
|
|
### Overview |
|
|
|
YAGO 4.5 is the latest version of the YAGO knowledge base. It is |
|
based on Wikidata — the largest public general-purpose knowledge |
|
base. YAGO refines the data as follows: |
|
|
|
* All entity identifiers and property identifiers are human-readable. |
|
* The top-level classes come from schema.org — a standard repertoire |
|
of classes and properties maintained by Google and others. The lower |
|
level classes are a careful selection of the Wikidata taxonomy. |
|
* The properties come from schema.org. |
|
* YAGO 4.5 contains semantic constraints in the form of SHACL. These |
|
constraints keep the data clean, and allow for logical reasoning on |
|
YAGO. |

### Dataset Structure |
|
The dataset is structured as follows: |
|
|
|
- **raw/yago-taxonomy.ttl:** Contains the `rdfs:subClassOf` relations |
|
for YAGO and the prefix mappings for the N-Triples. |
|
- **raw/facts.tar.gz:** Compressed file containing chunks of the |
|
dataset in N-Triples format, representing the factual knowledge in |
|
YAGO. |
|
|
|
### Features |
|
|
|
Each RDF triple in the dataset is represented with the following features: |
|
|
|
- **subject:** The subject of the triple, representing the entity. |
|
- **predicate:** The predicate of the triple, representing the |
|
relationship between the subject and object. |
|
- **object:** The object of the triple, representing the entity or |
|
value linked by the predicate. |
|
|
|
### Splits |
|
|
|
The dataset is logically divided into multiple chunks, each containing |
|
a subset of RDF triples. Users can load specific chunks or the entire |
|
dataset based on their requirements. |
|
|
|
## Usage |
|
|
|
### Loading the Dataset |
|
|
|
The dataset can be loaded using the Hugging Face `datasets` library as follows: |
|
|
|
```python |
|
from datasets import load_dataset |
|
|
|
dataset = load_dataset('wikipunk/yago-4.5-en', num_proc=4) |
|
``` |
|
|
|
### Accessing the YAGO Taxonomy File |
|
|
|
The `yago-taxonomy.ttl` file can be accessed and loaded in every process as follows: |
|
|
|
```python |
|
from rdflib import Graph |
|
|
|
taxonomy_graph = Graph() |
|
taxonomy_graph.parse('raw/yago-taxonomy.ttl', format='turtle') |
|
``` |
|
|
