+ # govdocs1: source PDF files
86
+
87
+ > [!NOTE]
88
+ > Converted versions of other document types (word, txt, etc) are available [in this repo](https://huggingface.co/datasets/BEE-spoke-data/govdocs1-by-extension)
89
+
90
+ This is ~220,000 open-access PDF documents (about 6.6M pages) from the dataset [govdocs1](https://digitalcorpora.org/corpora/file-corpora/files/). It wants to be OCR'd.
91
+
92
+
93
+ - Uploaded as `tar` file pieces of ~10 GiB each due to size/file count limits with an [index.csv](data/index.csv) covering details
94
+ - 5,000 randomly sampled PDFs are available unarchived in `sample/`. Hugging Face supports previewing these in-browser, for example [this one](sample/001070.pdf)
95
+
96
+ ## Recovering the data
97
+
98
+ Download the `data/` directory (with `huggingface-cli download` or similar) extract the tar pieces:
99
+
100
+ ```sh
101
+ cat data_pdfs_part.tar.* | tar -xf - && rm data_pdfs_part.tar.*
102
+ ```
103
+
104
+ ## processing details
105
+
106
+ ### duplicates
107
+
108
+ exact duplicate PDFs were removed with `jdupes`. See the [log file](exact_duplicate_removal.log) for details.

220
+ #### Data Quality Issues
221
+
222
+ | Issue | Severity | Impact |
223
+ |-------|----------|---------|
224
+ | **Metadata Poverty** | **CRITICAL** | 79% missing subjects kills discoverability |
225
+ | **Title Degradation** | **HIGH** | 28% generic/missing titles |
226
+ | **Date Inconsistencies** | **MEDIUM** | Invalid formats, future dates |
227
+ | **Processing Errors** | **LOW** | 0.04% failure rate acceptable |
228
+
229
+ #### Key Insights
230
+
231
+ **Document Profile**: Typical government PDF = 10 pages, 0.15 MB, metadata-poor
232
+
233
+ **Fatal Flaw**: This dataset has excellent technical extraction (99.96% success) but catastrophic intellectual organization. You're essentially working with 230K unlabeled documents.
234
+
235
+ **Bottom Line**: The structural data is solid, but without subject classification for 79% of documents, this is an unindexed digital landfill masquerading as an archive.
