Dataset Summary
mammut-corpus-venezuela is a dataset for Spanish language modeling. This dataset comprises a large number of Venezuelan and Latin-American Spanish texts, manually selected and collected in 2021. The data was collected by a process of web scraping from different portals, downloading of Telegram group chats' history, and selecting of Venezuelan and Latin-American Spanish corpus available online. The texts come from Venezuelan Spanish speakers, subtitlers, journalists, politicians, doctors, writers, and online sellers. Social biases may be present, and a percentage of the texts may be fake or contain misleading or offensive language.
Each record in the dataset contains the author of the text (anonymized for conversation authors), the date on which the text entered in the corpus, the text which was automatically tokenized at sentence level for sources other than conversations, the source of the text, the title of the text, the number of tokens (excluding punctuation marks) of the text, and the linguistic register of the text.
The dataset counts with a train split and a test split.

Dataset Creation
Curation Rationale
The purpose of the mammut-corpus-ve dataset is language modeling. It can be used for pre-training a model from scratch or for fine-tuning on another pre-trained model.
Source Data
Initial Data Collection and Normalization
The data consists of opinion articles and text messages. It was collected by a process of web scraping from different portals, downloading of Telegram group chats’ history and selecting of Venezuelan and Latin-American Spanish corpus available online.
The text from the web scraping process was separated in sentences and was automatically tokenized for sources other than conversations.
An arrow parquet file was created.
