StackOverflow Knowledge Graph - GO

GO StackOverflow Knowledge Graph Datasheet

1. What This Dataset Is

This dataset is the GO-specific RDF shard of the Stack2Graph StackOverflow Knowledge Graph. Each MDC repository contains exactly one language dataset.

It is optimized for graph-based retrieval and SPARQL analytics (not row-wise tabular training input).

2. Repository Layout

schema.nt
go/
  part0.nt
  part1.nt
  ...

• schema.nt: shared ontology and schema triples.

• go/part*.nt: language-scoped instance triples serialized as N-Triples.

3. Data Model And Coverage

The graph links Stack Overflow entities and relations, including:

• questions

• answers

• comments

• tags

• vote aggregates

• 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

4. Recommended Preprocessing

1. Load schema.nt and all triples from go/ into an RDF-capable store.

2. Map language triples to named graph http://stackoverflow.com/go.

3. Keep schema triples available for graph-aware query planning.

4. Preserve attribution and license metadata during downstream export.

Example language-scoped query:

SELECT ?s ?p ?o
WHERE {
  GRAPH  {
    ?s ?p ?o
  }
}
LIMIT 100

5. Quality Notes And Caveats

• A Stack Overflow question may belong to multiple language shards when tagged with multiple languages.

• Vote information is represented as aggregates, not raw individual vote events.

• As with community-generated data, content may include noise, bias, and temporal drift.

6. Intended Use

• retrieval and question-answering systems

• RAG and hybrid retriever experiments

• knowledge graph benchmarking and diagnostics

• language-scoped developer tooling research

7. Limitations

• Not a complete mirror of all Stack Overflow content.

• Not all moderation context or full revision history is represented.

• Best used with graph infrastructure that supports named graphs and SPARQL.

8. Licensing And Attribution

This dataset inherits Stack Overflow source licensing and attribution requirements. Ensure compliant attribution and redistribution practices in all derived artifacts.
