umi golden corpus

Ten thousand real web pages, kept so that HTML extraction can be proved to produce byte identical output on every machine that runs it.

This is not a training corpus. It is a test fixture. The crawler it belongs to is umi, which lets people outside the project run fetchers, and the only thing that makes a fetcher somebody else runs trustworthy is that its extraction of a page can be compared against everyone else's byte for byte. A one in ten thousand divergence between two honest implementations is indistinguishable from a dishonest one, so ten thousand real pages is the rate the claim has to be measured at.

What is in it

One file, wide.parquet, with two columns:

column type what it is
url string the URL the page was fetched from
body binary the raw response body, exactly as it arrived

Ten thousand rows, 1.49 GB of HTML uncompressed, off 333 hosts. One row per distinct body, HTML content types only, ordered by URL. The bodies are raw bytes and not text on purpose: the encoding, the byte order marks and the broken markup are the interesting part.

How it is used

The expected extraction output lives in the umi repository at crates/umi-extract/golden/wide.txt, as three truncated blake3 digests per page: the input, the markdown and the plain text. The test that compares them is crates/umi-extract/tests/wide.rs.

curl -L -o wide.parquet \
  https://huggingface.co/datasets/open-index/umi-golden/resolve/main/wide.parquet
UMI_GOLDEN_CORPUS=$PWD/wide.parquet \
  cargo test -p umi-extract --test wide --release -- --ignored --nocapture

Provenance and licence

The pages were fetched by umi from public URLs, respecting robots.txt. They are published here as fetched, without modification, for the sole purpose of verifying that extraction is deterministic.

The selection, the schema and the file are CC0. The page contents are the work of whoever wrote them and their copyright is unaffected by being copied into a test fixture. If you are a site owner and would rather your pages were not in here, open an issue on the umi repository and they will be dropped and the corpus rebuilt.
