- # Java StackOverflow Vector Dataset Datasheet
16
-
17
- ## 1. What This Dataset Is
18
-
19
- This dataset is the Java-specific vector shard of the Stack2Graph StackOverflow retrieval corpus.
20
- Each Hugging Face dataset repository contains exactly one language dataset.
21
-
22
- It is optimized for dense+sparse retrieval, Qdrant restoration, and embedding-based RAG experiments.
23
-
24
- It is used in the Stack2Graph project as the vector counterpart to the language-scoped RDF knowledge graph shards.
25
-
26
- See the Stack2Graph repository for more details:
27
- [https://github.com/tha-atlas/Stack2Graph](https://github.com/tha-atlas/Stack2Graph)
28
-
29
- ## 2. Repository Layout
30
-
31
- ```text
32
- dataset_manifest.json
33
- question_metadata_*.parquet
34
- chunk_records_*.parquet
35
- question_records_*.parquet
36
- ```
37
-
38
- - `dataset_manifest.json`: language-scoped manifest for this dataset shard.
39
- - `question_metadata_*.parquet`: per-question metadata and retrieval bookkeeping.
40
- - `chunk_records_*.parquet`: chunk-level vector rows when parent-child indexing is enabled.
41
- - `question_records_*.parquet`: question-level vector rows when chunking is disabled or exported alongside chunk data.
42
-
43
- ## 3. Data Model And Coverage
44
-
45
- The dataset is derived from Stack Overflow questions selected for the Java programming language.
46
- It contains the structured records needed to rebuild the Stack2Graph Qdrant collection for that language.
47
-
48
- Coverage scope:
49
-
50
- - records are retained when they match the Stack2Graph supported language-tag set
51
- - this repository contains only the Java shard
52
- - the archive may contain both metadata-only and retrieval-ready vector rows depending on the export mode
53
-
54
- ## 4. Recommended Preprocessing
55
-
56
- 1. Read `dataset_manifest.json` first and use it as the source of truth for included Parquet files.
57
- 2. Load all Parquet shards for this repository into your vector indexing pipeline.
58
- 3. Rebuild or restore the Qdrant collection `stackoverflow_java_vector`.
59
- 4. Preserve attribution and license metadata during downstream export.
60
-
61
- ## 5. Automatic Download And Vector DB Setup
62
-
63
- You do not need to regenerate embeddings from GraphDB to use this dataset.
64
-
65
- In the Stack2Graph repository, you can use the automation script
66
- `python -m experiment.load_hf_datasets_into_services --skip-kg` to download dataset artifacts
67
- and prepare the vector database service state automatically.
68
-
69
- Typical workflow:
70
-
71
- 1. Clone and configure Stack2Graph (`.env` with HF token and service paths).
72
- 1. Clone and configure Stack2Graph (`.env` with HF token and service paths).
73
- 1. Start required local services:
74
-
75
- ```bash
76
- docker compose up -d
77
- ```
78
-
79
- 1. Run the loader script:
80
-
81
- ```bash
82
- python -m experiment.load_hf_datasets_into_services --skip-kg
83
- ```
84
-
85
- For manual usage without automation, directly ingest the listed Parquet files into your vector database.
86
-
87
- ## 6. Quality Notes And Caveats
88
-
89
- - A Stack Overflow question may belong to multiple language shards when tagged with multiple languages.
90
- - Embeddings and sparse representations depend on the configured export pipeline and model versions.
91
- - As with community-generated data, content may include noise, bias, and temporal drift.
92
-
93
- ## 7. Intended Use
94
-
95
- - semantic retrieval and reranking
96
- - RAG and hybrid retriever experiments
97
- - vector database benchmarking and diagnostics
98
- - language-scoped developer tooling research
99
-
100
- ## 8. Limitations
101
-
102
- - Not a complete mirror of all Stack Overflow content.
103
- - Not all export modes include the same row types or chunk layouts.
104
- - Best used together with the Stack2Graph retrieval pipeline and Qdrant-compatible tooling.
105
-
106
- ## 9. Licensing And Attribution
107
-
108
- This dataset inherits Stack Overflow source licensing and attribution requirements.
109
- Ensure compliant attribution and redistribution practices in all derived artifacts.
110
-
111
- ## 10. Suggested Citation
112
-
113
- If you use this dataset, cite the Stack2Graph work:
