+ # SFD: SEC Filings Dataset (v1)
32
+
33
+ **SFD-v1** is an open, layout-faithful reconstruction of U.S. Securities and Exchange Commission (SEC) EDGAR filings into token-efficient MultiMarkdown (MMD), targeted at long-context language modeling, financial reasoning, document understanding, and evaluation.
34
+
35
+ This release covers filings from **January 2022 through June 2025** (~3.4M filings), produced by the SFD parser described in:
36
+
37
+ > *The SEC Filings Dataset: Reconstructing U.S. Corporate and Financial Disclosures into Layout-Faithful and Token-Efficient Pretraining Data.* Anonymous Authors (NeurIPS 2026 Evaluations & Datasets Track, under review).
38
+
39
+ The full SFD corpus is estimated at ~500B tokens across ~18.4M filings (1994–present); this release is a public snapshot focused on the most recent four-and-a-half years.
40
+
41
+ ## Key facts
42
+
43
+ - **Format:** [MultiMarkdown](https://fletcher.github.io/MultiMarkdown-6/) — preserves merged-cell tables (`||` colspan, `^^` rowspan), indentation, and visual hierarchy that standard text extraction destroys.
44
+ - **Source formats handled:** HTML (\~62%), XML (\~18%), plaintext (\~18%), SGML (\~2%), PDF-via-OCR (\~1%) — see paper §3.
45
+ - **Filings:** ~3.4M parsed `.md` documents across 350+ filing types (10-K, 10-Q, 8-K, Form 4, N-PORT, 13F, 485BPOS, ABS-EE, …).
46
+ - **License:** CC-BY-NC-4.0 (parsed). Underlying SEC filings are U.S. Government public domain.
47
+ - **Storage:** Parquet shards with zstd-15 compression, one shard per (year, month).
48
+
49
+ ## Schema
50
+
51
+ Each row is one parsed filing.
52
+
53
+ | field | type | description |
54
+ |-------|------|-------------|
55
+ | `accession` | string | SEC accession number (e.g. `0000320193-24-000123`) |
56
+ | `file_stem` | string | Stem of the original submission file |
57
+ | `year` | int16 | Filing year |
58
+ | `month` | int8 | Filing month (1–12) |
59
+ | `parsed_md` | string | MultiMarkdown reconstruction of the filing |
60
+ | `char_count` | int64 | Character count of `parsed_md` |
61
+ | `md5` | string | MD5 of `parsed_md` (UTF-8) |
62
+ | `has_ocr` | bool | True if any portion required Mistral OCR |
63
+ | `source_format` | string | Primary source format (`html`, `xml`, `plaintext`, `sgml`, `pdf`) |
64
+
65
+ ## Loading
66
+
67
+ ```python
68
+ from datasets import load_dataset
69
+
70
+ ds = load_dataset("anonymous-md/EDGAR_FILINGS_DATASET", split="train", streaming=True)
71
+ for row in ds.take(1):
72
+ print(row["accession"], row["year"], row["month"], len(row["parsed_md"]))
73
+ ```
74
+
75
+ For a full local materialization (~50 GB on disk):
76
+
77
+ ```python
78
+ ds = load_dataset("anonymous-md/EDGAR_FILINGS_DATASET", split="train")
79
+ ds = ds.filter(lambda r: r["year"] == 2024) # or by month, source_format, etc.
80
+ ```
81
+
82
+ To recover the canonical SEC EDGAR URL for any row:
83
+
84
+ ```python
85
+ acc = row["accession"] # e.g. "0000320193-24-000123"
86
+ acc_clean = acc.replace("-", "")
87
+ url = f"https://www.sec.gov/Archives/edgar/data/{int(acc.split('-')[0])}/{acc_clean}/"
88
+ ```
89
+
90
+ ## Sample subset (for reviewer inspection)
91
+
92
+ Because the full corpus exceeds 4 GB, a small sample is provided at
93
+ `sample/sfd-v1-sample.parquet` to allow quick inspection of data quality without
94
+ materializing the full dataset.
95
+
96
+ - **Path:** `sample/sfd-v1-sample.parquet`
97
+ - **Sampling methodology:** stratified by year — first/last representative month
98
+ of each year in the release (2022-01, 2023-01, 2024-01, 2025-01, 2025-06),
99
+ with the first 25 rows from each, sorted by accession. This surfaces a mix of
100
+ source formats (HTML / XML / SGML / PDF-OCR) and form types (Form 4, 10-Q,
101
+ 8-K, NPORT-P, etc.) representative of the full corpus.
102
+ - **Loading:** `pq.read_table("sample/sfd-v1-sample.parquet")` with the same
103
+ schema as the full dataset.
104
+
105
+ ## Methodology summary
106
+
107
+ SFD treats filings as 2-D rendered grids rather than DOM trees:
108
+
109
+ - **HTML:** Reconstructs the *visual* coordinate system; collapses the "Three-Column Hack" (\$ / value / closing-paren split into separate cells); coalesces fragmented multi-row headers using `border-*` and `margin-*` cues; preserves indentation hierarchy by binning CSS units into discrete `&nbsp;` levels.
110
+ - **XML:** Routes 33 specialized schemas (Forms 3/4/5, 13F, N-PORT, N-CEN, etc.) through schema-aware emitters that reconstruct human-readable disclosures from field hierarchies.
111
+ - **Plaintext / SGML:** Wraps fixed-width legacy filings in code fences to preserve column alignment; collapses 3+ blank lines to 2.
112
+ - **PDFs:** Run through Mistral OCR 3 in 10-page batches; HTML table fragments converted to MMD; near-blank pages skipped via pixel-variance filter.
113
+
114
+ Every row is prepended with `<SEC-HEADER>`-derived metadata (CIK, SIC, filing type, period of report, etc.) so each filing is self-contained.
115
+
116
+ See paper §3 for full details.
117
+
118
+ ## Companion benchmarks
119
+
120
+ Two evaluation benchmarks are derived from SFD and reported alongside this dataset:
121
+
122
+ - **EDGAR-OCR** — 300 hand-selected SEC tables, synthetically perturbed for contamination resistance, scored by adjusted recall over (content × placement × inline formatting).
123
+ - **EDGAR-Forecast** — 50 companies × 5 numeric targets each (250 total) drawn from 2026 10-Q filings, evaluated agentically with prior 5-year filing history visible.
124
+
125
+ Released separately when scoring is finalized.

139
+
140
+ - **Parsed corpus (this release):** [CC BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/) — non-commercial use only with attribution. Derivative works must keep this notice.
141
+ - **Underlying raw filings:** U.S. Government public domain, available canonically from the SEC EDGAR system at <https://www.sec.gov/edgar>. Redistribution of raw filings under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) attribution-style metadata is permitted.
142
+ - **Mistral OCR outputs** (the small PDF subset, `has_ocr == True`) are subject to the [Mistral AI Terms of Service](https://mistral.ai/terms/) at the time of generation; downstream redistribution within this CC BY-NC 4.0 corpus is permitted.
143
+
144
+ ## Ethics, privacy, limitations
145
+
146
+ - All filings are public regulatory disclosures with no expectation of privacy.
147
+ - The dataset preserves filer-supplied content verbatim; SFD does **not** correct factual or accounting errors in the source filings.
148
+ - The MMD reconstruction is high-fidelity but not perfect; estimated ~99% structural/semantic accuracy. A small minority of filings (notably highly visual exhibits with low OCR-recoverable content) may have degraded representation.
149
+ - Token counts reflect the Qwen3-1.7B tokenizer; other tokenizers will differ.
150
+
151
+ ## Provenance & versions
152
+
153
+ - **v1** (this release): 2022-01 → 2025-06, parsed by SFD pipeline rev `sec_parser`.
154
+ - Future releases will extend coverage to 1994–2021 and incrementally to 2025-07+.

This release covers ~3.4M filings filed between January 2022 and June 2025, parsed from heterogeneous HTML, XML, plaintext, SGML, and PDF source formats. Tables are reconstructed using MultiMarkdown span notation (`||` for column spans, `^^` for row spans), preserving merged cells, multi-row headers, and indentation hierarchies that standard text extraction destroys. SFD-v1 supports long-context language modeling, financial reasoning, document understanding, and evaluation. The full SFD corpus is estimated at ~500B tokens across ~18.4M filings (1994-present); this release is a public snapshot of the most recent 4.5 years.",
