Hungarian Webcorpus 2.0
The new version of the Hungarian Webcorpus was built from Common Crawl and includes a little over 9 billion words. As opposed to the original Webcorpus, the document structure is left intact. This ensures that long-range dependencies inside documents are retained, and allows the training of models that can exploit them (e.g. BERT, Tranformer-XL, etc).
The corpus is disseminated as tsv files in the CoNLL-U format. The annotations were produced by
The corpus can be downloaded in two versions, which differ in the number of fields in the tsv files:
- The clean corpus contains the surface form, the whitespaces after each token, and the lemma and the POS tag assigned by
- The analyzed corpus includes the
anafield in addition to the others, which lists all possible morphological analyses of the surface form.
For most use cases, the clean version should be sufficient. It is also only 83GB, which makes it easier to handle and faster to process than the 511GB analyzed version. In any case, please note that the corpus is very large, so make sure you have the appropriate infrastructure to process it. Also, please refrain from streaming the data from our repository. The best way to start is to download a few files, familiarize yourself with it and iron out any bugs in your code before running it on the whole corpus.
Both folders include a
sha256sums file that contains the sha256 checksums for all tsv files. The integrity of the corpus then can be checked by running
sha256sum -c sha256sums.
Code for processing the corpus can be downloaded from the cc_corpus GitHub repository. Feature requests should also be reported there.
