Filtering Steps
Each snapshot was processed as follows:
- Used Creative Commons extractor from the Dolma Toolkit to filter pages with Creative Commons or Public Domain license. This approach was addapted from the C4Corpus porject by Habernal et al (2016)
- Deduplication on exact URL match
- Filtering using subset C4 heuristic: removed pages containing
javascript,lorem ipsum, and curly braces. - Filtering using Gopher quality and duplication heuristics.
- Dolma repetition heuristics: removed of documents containing more than than repeated n-grams.
- Removed any page with non-commercial (NC) or no-derivatives (ND) variants of Creative Common licenses.
- Removal of pages with 80% duplicated ngrams.
