The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The n-gram-based filtering strategy detects high levels of textual redundancy between articles and removes such low-quality articles from the corpora entirely, yielding linguistically rich texts suitable for language model training.

C2weakest assumption

That repetitive n-gram patterns reliably mark low-quality database-generated articles while preserving original, high-information content across the seven languages.

C3one line summary

A two-phase pipeline extracts clean text from Wikimedia dumps and applies n-gram filtering to remove repetitive low-quality articles for South Slavic language corpora.

[3] T ext extraction Once the raw dumps are converted into line‑oriented JSON (JSONL) files, each page is processed in batches to extract usable text and metadata

[4] Initial cleaning and parsing : Applies first regex pass to reduce markup noise and parses the text into a structured representation using mwparserfromhell library

[5] Category handling: Identifies and extract category tags into a separate variable, while also removing category markup from the text
