Quentin, I am not sure dataset itself should cut articles into sentences (unless there is an option for both articles/sentences). Perhaps other models might need entire articles as input. If needed, users can sentence tokenize articles using nltk/spacy and such. I’ll play with the wikipedia dataset in the coming days and I’ll report back to you my experiences. Also, while looking at the dataset I found references to Categories and such. Perhaps equally important objective for wikipedia dateset is to keep it as clean as possible.
