Universal-Verified-Wiki-Historian-American-History

Universal-Wiki-Historian is an instruction-following dataset of historical summaries with source citations, designed for training source-aware historical QA and explanation systems.

Dataset Summary

This release contains 7,318 approved instruction-context-response triples centered on historical figures and events. Each example asks a model to "Act as a world-class historian," provides a contextual passage, and delivers a factual summary that often includes in-text citations (e.g., [1], [2]) linked to provided source information. It is designed to support training and evaluation for citation-aware historical explanation generation.

This card expands the broader Universal-Wiki-Historian project card with the additional work performed in this checkout: DeepSeek-based quality auditing, targeted correction of failed records, offline schema/procedural validation, and a final approved JSONL export for Hugging Face publication.

Key characteristics:

Domain: U.S. history, with a strong focus on U.S. presidents, the Civil War era, and legal/constitutional topics.
Instruction format: Always begins with "Act as a world-class historian specializing in … Summarize the facts and provide citations."
Context: Source-grounded passages or excerpts used as factual background.
Response: A concise factual summary, usually with inline numeric references to supporting source entries.
Sources: Source citation strings supporting the response. The sources and Validation Sources fields are mixed-format fields and may appear either as lists or formatted strings.

The data is provided in a single JSONL file (final_approved_train.jsonl). This dataset card was generated on 2026-06-28.

Relationship to the Broader Universal-Wiki-Historian Project

The broader Universal-Wiki-Historian project is organized around a chain-of-custody principle: training records should remain traceable from instruction-context-response objects back to source material, citation metadata, validation decisions, and release artifacts. The upstream project card describes a larger pipeline involving raw Wikipedia-style dumps, citation indexing, topic skeletons, recursive topic expansion, formatting, deduplication, semantic validation, citation-integrity checks, and human review.

This checkout does not include every upstream artifact referenced by that project-level card, such as core/, raw_files/, config/skeletons/, or the full citation-index logs. This release card therefore documents the local approved JSONL release and the extra curation layer applied here, while preserving the upstream intent: source-aware historical generation with citation metadata and conservative quality controls.

Additional Processing in This Release

On top of the upstream Universal-Wiki-Historian pipeline, this local release adds a DeepSeek-assisted dataset grading and repair pass.

Local release artifacts:

Artifact	Records
`train.jsonl`	9,265
`failed_audit_train.jsonl`	7,691
`corrected_train.jsonl`	7,590
`final_approved_train.jsonl`	7,318
`final_rejected_validation_train.jsonl`	271
`perfected_final_approved_train.jsonl`	7,318

The local curation flow included:

DeepSeek quality audit: audit_datasets_deepseek.py evaluated records for accuracy plausibility and formatting integrity using deepseek-v4-pro.
Failure routing: records with audit failures were written to failed-audit exports for correction rather than promoted directly.
Targeted reconstruction: dataset_corrector_deepseek.py used DeepSeek Pro/Flash routing to rewrite failed responses while preserving the original instruction, context, source fields, and row fingerprint.
Procedural validation: third_pass_validation.py checked required keys, casing, null/empty fields, placeholder text, malformed JSON, and terminal punctuation.
Final approval split: records that passed the validation stage were exported to final_approved_train.jsonl; rejected records were retained separately for review.

The DeepSeek audit log contains completed judgments over thousands of rows, and the correction/validation logs are preserved under logs/. These logs provide operational provenance for this release but should not be treated as a substitute for independent historical fact verification.

Supported Tasks

Text generation (instruction-following, summarization)
Question answering (open-domain QA, fact-verification)
Citation generation / source attribution
Explanation generation (historical fact explanation)

The dataset is well-suited for fine-tuning language models to produce source-aware answers, to follow historian-style instructions, and to practice citation-style attribution.

Languages

All content is in English (US English, with historical quotations and spellings).

Dataset Structure

The dataset consists of 7,318 records stored in a JSONL file. Each record is a dictionary with six fields. An example structure is shown below:

{
  "instruction": "Act as a world-class historian specializing in President of the United States. Summarize the facts and provide citations.",
  "context": "In Trump v. United States, on July 1, 2024, the Supreme Court ruled that ...",
  "response": "The Supreme Court's July 1, 2024, ruling in Trump v. United States established that ... [1] ...",
  "sources": ["...", "..."],
  "Validation Sources": ["...", "..."],
  "_fingerprint": "daa5386452495fd3c95a71520f3d928e"
}

Data Fields

Field	Type	Description
`instruction`	string	The task instruction (e.g., "Act as a world-class historian specializing in … Summarize the facts and provide citations.")
`context`	string	A passage of source text providing the factual background.
`response`	string	The generated factual summary. Many responses include inline citation markers (`[1]`, `[2]`, etc.) that refer to supporting source entries.
`sources`	list of strings or string	The raw source citations used to support the response. Most records store this as a list of strings; some records store a formatted string.
`Validation Sources`	list of strings, string, or empty/`null`	A validation or reformatted-source field. The field is mixed-format: some records contain lists, some contain a single formatted string with bracketed numbers, and 2 records have a missing value.
`_fingerprint`	string	A hash (likely MD5) of the record content, used for deduplication or internal tracking.

Data Splits

No predefined train/validation/test split is provided. The entire dataset appears as a single training file (final_approved_train.jsonl). Users should create their own splits for model training and evaluation. It is recommended that the maintainer add official split information for standardized benchmarking.

Dataset Creation and Processing

The broader project card describes an upstream source-ingestion and citation-indexing workflow, while this release card documents the local DeepSeek audit/correction/validation layer. Some upstream creation details are still not fully available in this checkout. The available local metadata does not document the exact methods used to:

choose historical topics and instructions,
extract or compose the context texts,
generate the response summaries and citations,
perform quality control or human review, are currently unknown.

The Validation Sources field suggests an additional validation or formatting pass over citations, but no documentation explains the exact process. The maintainer should add a detailed dataset creation statement, including any use of language models, human annotation, automated filtering, or manual review.

Data Quality and Validation

Source verification: The presence of a separate Validation Sources field indicates an attempt to verify or standardize citations. Because the field is mixed-format and the validation process is not documented, users should treat it as useful supporting metadata rather than a guarantee of factual accuracy.
Missing values: Only 2 records out of 7,318 have a missing Validation Sources (null/empty), a negligible rate.
Citation coherence: Many responses contain inline numeric citations that appear intended to map to entries in the source fields. Users should validate this mapping before training citation-critical systems.
No explicit quality metrics: No inter-annotator agreement, factual accuracy scores, or human evaluation results are reported. While the responses appear factually coherent and well-formatted, the dataset should be used with an understanding that factual correctness is not guaranteed.

Intended Uses

Fine‑tuning language models for instruction‑following generation with citation-style attribution.
Training source attribution and fact‑verification components.
Research on explainable historical QA and citation‑supported summarization.
Educational applications: teaching models to respond like a historian, providing referenced facts.

The dataset is intended for research and development of NLP systems, not for production decision-making without additional safeguards.

Out‑of‑Scope Uses

High‑stakes applications: The data should not be used as a primary source of factual truth. Generated outputs must be independently verified before use in legal, political, or critical decision contexts.
Propaganda or misinformation: Using the dataset to create systems that generate biased or false historical narratives without source verification is strongly discouraged.
Direct answer engines: Without further checks, the model may hallucinate facts or misattribute citations.

Limitations

Domain narrowness: Heavily concentrated on U.S. history, especially presidential biographies and American political/legal events. Limited representation of non‑U.S. history, global perspectives, or underrepresented historical figures.
Language: English only.
Size: With 7,318 examples, the dataset is relatively small for training general-purpose models; it may be best used for fine‑tuning or domain‑adaptation tasks.
Citation formatting variation: The sources and Validation Sources fields exhibit inconsistent formatting (sometimes a single string with embedded brackets, sometimes a list), which may complicate automated processing.
Unknown provenance: The origin of the context texts and the method of generating responses are not documented, making it difficult to assess potential bias or quality thoroughly.

Bias and Risk Considerations

Source bias: Source strings in the dataset include major Western news outlets and established historical texts. This may reinforce mainstream narratives and exclude alternative viewpoints or marginalized histories.
Historical perspective: The instruction to "act as a world‑class historian" may implicitly carry assumptions about “authoritative” history. Users should be aware that the dataset may reflect the biases of its source materials and the generation process.
Political sensitivity: Topics include impeachment, presidential pardons, and war decisions, which are subject to interpretation. Outputs trained on this data could inadvertently present one‑sided views if not carefully balanced.
Factual verification: The dataset does not guarantee factual accuracy; all generated summaries and citations should be cross‑checked with primary sources.
