Source classes

The processing pipeline separates books and uploaded documents, academic articles, theses, news, columns, and other reviewed web sources. These classes describe ingestion provenance; they do not grant redistribution rights.

Processing method

  1. Source identity and duplicate checks.
  2. Text extraction, OCR review, and noise filtering where required.
  3. Sentence segmentation, token alignment, and context-sensitive lemmatization.
  4. Incremental indexing and derived measurements in ClickHouse.

Temporal coverage

A reliable aggregate source-publication range is not yet available for every record, so no artificial start or end year is published. Corpus-ingestion timestamps are kept separate from source publication dates.

Query access and citation

The public interface returns bounded query results and derived measurements; it does not expose a bulk corpus export.

Fields deliberately omitted
