+# Dataset Card for Testimole -- A multi-billion tokens Italian text corpus
 ![image/jpeg](https://cdn-uploads.huggingface.co/production/uploads/65c27751d2fbc4e846637421/c726oXPuXRbFrLiAZqKs5.jpeg)
+Testimole is a large linguistic resource for Italian obtained through a massive web scraping effort. As of June 2024, it is one of the largest datasets for the Italian language, if not the largest, publicly available, consisting of almost 100B tokens counted with the Tiktoken cl100k BPE tokenizer. It consists mainly of conversational data (Italian Usenet hierarchies, Italian message boards, Italian subreddits) but also contains other textual data derived from blogs, wikis, websites, and academic journals. Each data source is separated into a different dataset split.
+Testimole is a wordplay combining "Testi" (texts) and "Mole." "Mole" refers to one of the most famous monuments of Torino, the [Mole Antonelliana](https://en.wikipedia.org/wiki/Mole_Antonelliana), where this dataset was conceived and built. Moreover, "mole" means "mass" or "bulk" in Italian, highlighting the large size of this dataset. Testimole is also similar to the word "Testimone" (witness), emphasizing the diachronic quality of the data, thus being a witness of the passage of time in the Italian webosphere.
+## Dataset Details
+### Dataset Description
+The goal of this work is to create a huge linguistic resource for the Italian language that can be used for several NLP applications, including but not limited to language modelling. The dataset is the result of a massive web scraping effort going on from February 2024 to May 2024, so the resources have a cut-off date comprised within this time span.
+There is a project to further expand the dataset, as explained in the "Future Plans" section.
+To create the dataset, I developed several scripts using Python3 and libraries such as BeautifulSoup and Selenium; the scripts were mostly written and executed manually, making it an extremely time-consuming project. The texts span different topics and periods, containing several divergent opinions and beliefs, in accordance with the main ideas of the "Perspective Data Manifesto" [1]. It is important to note that these data alone are not enough to train an Italian large language model from scratch, mainly not due to the size of the data but because, even if they span different topics, they are far from covering the broad range of subjects, information, culture, and techniques required to train a state-of-the-art model. Also, as will be better pointed out later, while it is safe to use these data under Fair Use for research purposes, users must investigate potential copyright infringement for other possible purposes. The Tiktoken BPE tokenizer with the cl100k_base model [2] was used for tokenization. This dataset is composed of several sub-datasets, each with different types of data and goals.
+## Uses
+Because this dataset consists of a large amount of texts in the Italian language, it can be used for all Natural Language applications that seek to improve support for Italian in a multilingual context and require data for training. This includes, but is not limited to, training large language models. Other possible uses are sentiment analysis, diachronic data classification (as the majority of the data is date-tagged), and text classification. Researchers are invited to annotate even small parts of this dataset. In such cases, the data could be used for other tasks as well, such as Named Entity Recognition (NER), Part-of-Speech (POS) tagging, information retrieval, summarization, and more. This versatility makes the dataset a valuable resource for various NLP projects and research endeavors.
+### Out-of-Scope Use

+## Dataset Creation
+### Curation Rationale
+Multilinguality is one of the main challenges for the new AI and NLP revolution that is taking place in the 2020s. Until now, the most advanced models are mostly trained on English or a few other languages, creating a dangerous gap for people speaking other languages (that is, 81.2% of the world population, according to the CIA Factbook of 2022) in accessing these new advanced instruments. Translations from English are not enough to capture the cultural differences of peoples that do not belong to the Anglo-American culture. Thus, it is important for a general model to be truly inclusive by including data that can capture different views of the world and uses of language. These data are not only useful for modeling the Italian language itself but also for gaining insights into Italian culture and the way in which Italian-speaking people engage with various topics.
+### Source Data
+* Usenet
+* Message boards
+* Blogs
+* Websites
+* Open Journal System platforms hosted by Italian universities or included in DOAJ
+* LiberLiber
+* Wikimedia
+#### Data Collection and Processing
+The dataset is the result of a massive web scraping effort that was carried out using manually created Python3 scripts using libraries such as BeautifulSoup for HTML parsing and Selenium in the few cases in which Javascript support or browser automatization was required. I have created blueprints of the script, such a generic "forum scraper" or "blog scraper" script but then I had to adapt them almost manually for each resource included in the dataset. Some resources were sharing the same technical platform, so it was trivial to adapt the script, in other case a significant reverse-engineering effort was required.
+The scraping took place on very simple resources: a very old unused 2006 Sony Vaio laptop with an Intel Core2Duo processor connected to a domestic FTTC connection was enough for the majority of websites, while in other cases other resources were rented or borrowed in order to have a speed-up or to aggregate and analyse the entire collection of data. Using such a simple setup was also a way to have a "natural" anti-overload system. Because many web scraping instances were running in parallel, websites were not loaded so much and often timeouts were implemented in order to protect smaller servers. It never happened that a website was slowed down due to this scraping process, that was crafted to be as gentle and slow as possible.
+Considering an average power consumption of the laptop of 40W and 100 days of running, circa 96Kwh were used to power the laptop. The laptop was plugged in the Italian-Centre electricity zone, with an average electricity/co2 ratio of 250g per KW with more than 60% of power coming from renewable sources. This means that the laptop Co2 emissions were circa 24KG of Co2, equivalent to a short 150km trip on a small car with emissions of 160g/km.
+All the data were collected in a JSONL format and then merged, cleaned, analyzed and converted to an Hugging Face dataset using an HPC resource that was gently provided to the author.
+The vast majority of data coming from forums undergone a process of deduplication in order to avoid the case of having two instances of the same message.
+#### Who are the source data producers?
+Data is produced by users of the Italian Internet mostly between 1995 and 2024. This resource also contains texts produced before 1995, such as the content of public domain books written by authors from any historical period.
+## Recommendations
+This dataset could be used along with other Italian natural language resources. A very good list of them is available at the address [https://huggingface.co/collections/gsarti/italian-nlp-resources-64fc606927fb3a92e9ea72f2]. For example, gsarti/clean_mc4_it [https://huggingface.co/datasets/gsarti/clean_mc4_it], being the biggest as-to-date cleaned version of Common Crawl for Italian, could be used to increase the variety of the data for the training of a Large Language Model.
+### Deduplication
 The presence of duplicate text can be, depending from the use cases, a
 big problem for several machine learning tasks. I tried to avoid as much
 the website. All the HTML was converted using HTML2TEXT so it should not
 contain html code.

+}
+```
+## Future work
+The dataset could be enhanced in several ways:
+* Increasing the amount of data (scraping): this could be done both by recycling the same scripts for other forums, blogs and websites or by writing new scraping scripts. It is important to understand that, even if the dataset is big, it only capture a small amount of the entire Italian webosphere;
+* Increasing the amount of data (not by scraping): we have projects in mind to increase the dataset with high quality contents coming from different sources, expecially from Italian Universities;
+* Cleaning the data: deduplication, as explained in the appropriate section, is probably the top-priority work that should be done on this dataset;
+* Much more :) You are warmly invited to collaborate with me in this effort.
+## Statistics
+More statistics will be added in the near future. In the "asset" directory, JSONL files contain precomputed token counts for each subcategory (e.g., single forum, newsgroup, or blog), allowing anyone interested to easily craft more detailed statistics.
