	### Dataset Summary

	Carolina is an Open Corpus for Linguistics and Artificial Intelligence with a
	robust volume of texts of varied typology in contemporary Brazilian Portuguese
	(1970-2021). This corpus contains documents and texts extracted from the web
	and includes information (metadata) about its provenance and tipology.

	The documents are clustered into taxonomies and the corpus can be loaded in complete or taxonomy modes. To load a single taxonomy, it is possible to pass a code as a parameter to the loading script (see the example bellow). Codes are 3-letters string and possible values are:

	- `dat` : datasets and other corpora;
	- `jud` : judicial branch;
	- `leg` : legislative branch;
	- `pub` : public domain works;
	- `soc` : social media;
	- `uni` : university domains;
	- `wik` : wikis.

	Usage Example:

	```python
	from datasets import load_dataset

	# to load all taxonomies
	corpus_carolina = load_dataset("carolina-c4ai/corpus-carolina")

	# to load social media documents
	social_media = load_dataset("carolina-c4ai/corpus-carolina", taxonomy="soc")
	```

	### Supported Tasks

	Carolina corpus was compiled for academic purposes,
	namely linguistic and computational analysis.


	### Languages

	Contemporary Brazilian Portuguese (1970-2021).

	## Dataset Structure

	Files are stored inside `corpus` folder with a subfolder
	for each taxonomy. Every file folows a XML structure
	(TEI P5) and contains multiple extracted documents. For
	each document, the text and metadata are exposed as
	`text` and `meta` features, respectively.

	### Data Instances

	Every instance have the following structure.

	```
	{
	"meta": datasets.Value("string"),
	"text": datasets.Value("string")
	}
	```

	\| Code \| Taxonomy \| Instances \| Size \|
	\|:----:\|:---------------------------\|----------:\|-------:\|
	\| \| Total \| 1745187 \| 7.3 GB \|
	\| dat \| Datasets and other Corpora \| 1098717 \| 3.3 GB \|
	\| wik \| Wikis \| 603968 \| 2.6 GB \|
	\| jud \| Judicial Branch \| 38068 \| 1.4 GB \|
	\| leg \| Legislative Branch \| 14 \| 20 MB \|
	\| soc \| Social Media \| 3449 \| 15 MB \|
	\| uni \| University Domains \| 945 \| 9.4 MB \|
	\| pub \| Public Domain Works \| 26 \| 3.6 MB \|
	\|\|


	### Data Fields

	- `meta`: a XML string with a TEI conformant `teiHeader` tag. It is exposed as text and needs to be parsed in order to access the actual metada;
	- `text`: a string containing the extracted document.

	### Data Splits

	As a general corpus, Carolina does not have splits. In order to load the dataset, it is used `corpus` as its single split.


	## Additional Information


	### Dataset Curators

	The Corpus Carolina is developed by a multidisciplinary
	team of linguists and computer scientists, members of the
	Virtual Laboratory of Digital Humanities - LaViHD and the Artificial Intelligence Center of the University of São Paulo - C4AI.

	The Open Corpus for Linguistics and Artificial Intelligence (Carolina) was
	compiled for academic purposes, namely linguistic and computational analysis.
	It is composed of texts assembled in various digital repositories, whose
	licenses are multiple and therefore should be observed when making use of the
