GO StackOverflow Knowledge Graph

Summary

This Hugging Face dataset repository contains the GO shard of the Stack2Graph StackOverflow Knowledge Graph. Hugging Face uses one dataset repository per programming language, so this repository is directly cloneable without an extra top-level archive wrapper.

The artifact is optimized for graph-based retrieval, SPARQL analytics, and retrieval-augmented question answering over Stack Overflow content.

• README.md: Hugging Face dataset card rendered from this template.
• schema.nt: shared ontology and schema triples.
• go/part*.nt: GO instance triples serialized as N-Triples.

Data Model And Coverage

The graph links Stack Overflow entities and relations, including questions, answers, comments, tags, vote aggregates, and question-to-question links.

Coverage scope:

• records are retained when they match the Stack2Graph supported language-tag set
• this repository contains only the GO shard
• a question may appear in more than one language repository when it has multiple programming-language tags

Recommended Use

Use this dataset for graph retrieval, SPARQL diagnostics, RAG experiments, and knowledge graph research for programming topics. It is not intended as row-wise tabular training input.

Load schema.nt and the files under go/ into an RDF-capable store. Map language triples to named graph:

http://stackoverflow.com/go

Example language-scoped query:

SELECT ?s ?p ?o
WHERE {
  GRAPH <http://stackoverflow.com/go> {
    ?s ?p ?o
  }
}
LIMIT 100

Restore With Stack2Graph

You do not need to rebuild triples from XML to use this dataset.

Typical workflow:

1. Clone Stack2Graph and configure .env with service paths and an HF token.
2. Start local services:

docker compose up -d

3. Download and prepare the knowledge graph service state:

python -m experiment.sources.hf

Quality Notes

• Vote information is represented as aggregates, not raw individual vote events.
• Not all moderation context or full revision history is represented.
• Community-generated Stack Overflow content may contain errors, outdated information, bias, or temporal drift.
