| | # Data Provenance
|
| |
|
| | Per-table documentation of data sources, extraction methods, and quality notes.
|
| |
|
| | ## documents
|
| |
|
| | **1,424,673 rows.** One row per PDF file from the DOJ Epstein release.
|
| |
|
| | - **856,028 files** processed with **Gemini 2.5 Flash Lite** ($0.10/$0.40 per 1M tokens). Full structured extraction: document type classification, date parsing, entity extraction, handwriting/stamp detection, photo description.
|
| | - **531,279 files** (DataSet 9) imported from the [rhowardstone/Epstein-research-data](https://github.com/rhowardstone/Epstein-research-data) community project using **Tesseract OCR**. Raw text only — no entity extraction or document classification. These have `ocr_source = 'tesseract-community'`.
|
| | - **1,377 files** originally Tesseract, upgraded to Gemini in v2 (604 from DS10, 773 from other datasets).
|
| | - **37,369 files** have `is_photo = true` (photos, stamps, blank pages).
|
| | - `email_fields` column (new in v2): JSON-encoded email metadata (from, to, cc, subject, date) for email-type documents.
|
| |
|
| | Distinguish OCR source: `ocr_source IS NULL` = Gemini, `ocr_source = 'tesseract-community'` = community.
|
| |
|
| | ## entities
|
| |
|
| | **10,629,198 rows.** Named entities extracted from documents.
|
| |
|
| | - Gemini documents: entities come from the structured JSON extraction prompt (types: person, organization, location, date, reference_number, email_address, phone_number, monetary_amount).
|
| | - Community documents: entities from post-processing NER pipeline.
|
| | - Entity `normalized_value` provides cleaned/canonical forms where available.
|
| |
|
| | ## chunks
|
| |
|
| | **2,193,090 rows.** Text chunks for RAG (retrieval-augmented generation).
|
| |
|
| | - ~800 token target per chunk with overlap at sentence boundaries.
|
| | - `char_start` and `char_end` map back to the parent document's `full_text`.
|
| |
|
| | ## embeddings_chunk
|
| |
|
| | **2,111,356 rows.** 768-dimensional float32 vectors from `gemini-embedding-001`.
|
| |
|
| | - ~96% coverage (documents with malformed text excluded).
|
| | - Stored as `list<float32>` in Parquet.
|
| | - `source_text_hash` links to the chunk text that was embedded.
|
| |
|
| | ## persons
|
| |
|
| | **1,614 rows.** Curated person registry with canonical names, aliases, and categories.
|
| |
|
| | - Categories: perpetrator, victim, associate, other.
|
| | - `aliases` field: JSON array of known alternate names/spellings.
|
| | - `search_terms`: additional search patterns for entity resolution.
|
| | - Community-curated from multiple sources.
|
| |
|
| | ## kg_entities / kg_relationships
|
| |
|
| | **467 entities, 2,198 relationships.** Knowledge graph connecting people, organizations, and locations.
|
| |
|
| | - Relationship types: traveled_with, associated_with, employed_by, legal_representative, financial_connection, etc.
|
| | - `weight` indicates strength of connection (co-occurrence frequency).
|
| | - `evidence` field links to source document file_keys.
|
| |
|
| | ## recovered_redactions
|
| |
|
| | **37,870 rows.** Text recovered from under redaction bars using ML reconstruction.
|
| |
|
| | - `interest_score` (0-100) ranks significance of recovered content.
|
| | - `names_found` lists person names detected in recovered text.
|
| | - Experimental quality — treat as leads, not verified text.
|
| |
|
| | ## financial_transactions (NEW in v2)
|
| |
|
| | **49,770 rows.** Credit card and bank transaction records extracted with DeepSeek.
|
| |
|
| | - Source: DOJ-released credit card statements and bank records (DataSet 10/11).
|
| | - Extraction model: DeepSeek (per-page structured extraction).
|
| | - 31% of raw extractions quarantined for quality issues (hallucinated amounts, duplicate entries, garbled OCR). Only clean records included.
