+## Latin part of cc100 corpus
+This dataset contains parts of the Latin part of the [cc100](http://data.statmt.org/cc-100/) dataset. It was used to train a [RoBERTa-based LM model](https://huggingface.co/pstroe/roberta-base-latin-cased) with huggingface.
+
+### Preprocessing
+
+I undertook the following preprocessing steps:
+
+  - Removal of all "pseudo-Latin" text ("Lorem ipsum ...").
+  - Use of [CLTK](http://www.cltk.org) for sentence splitting and normalisation.
+  - Retaining only lines containing letters of the Latin alphabet, numerals, and certain punctuation (--> `grep -P '^[A-z0-9ÄÖÜäöüÆ挜ᵫĀāūōŌ.,;:?!\- Ęę]+$' la.nolorem.tok.txt`
+  - deduplication of the corpus
+
+The result is a corpus of ~390 million tokens.
+
+### Structure
+The dataset is structured the following way:
+```
+{
+  "train": {
+              "text": "Solventibus autem illis pullum , dixerunt domini ejus ad illos : Quid solvitis pullum ?",
+              "text": "Errare humanum est ."
+              ...
+           }
+  "test":  {
+              "text": "Alia iacta est ."
+              ...
+           }
+}
+```
