_DESCRIPTION = """\
A dataset containing both DGA and normal domain names. The normal domain names were taken from the Alexa top one million domains. An additional 3,161 normal
domains were included in the dataset, provided by the Bambenek Consulting feed. This later group is particularly interesting since it consists of suspicious domain
names that were not generated by DGA. Therefore, the total amount of domains normal in the dataset is 1,003,161. DGA domains were obtained from the repositories
of DGA domains of Andrey Abakumov and John Bambenek. The total amount of DGA domains is 1,915,335, and they correspond to 51 different malware families. DGA domains
were generated by 51 different malware families. About the 55% of of the DGA portion of dataset is composed of samples from the Banjori, Post, Timba, Cryptolocker,
Ramdo and Conficker malware.

The data variable in the _generate_examples() method is a temporary variable that holds the portion of the dataset based on the current split.
The datasets.SplitGenerator in the _split_generators() method is responsible for creating the three different keys ('train', 'test', 'validation').When you load your
dataset using load_dataset(), the Hugging Face Datasets library will automatically call the _split_generators() method to create the three different dataset splits.
Then, it will call the _generate_examples() method for each split separately, passing the corresponding split name as the split argument.
This is how the different keys are created. To clarify, the _generate_examples() method processes one split at a time, and the Datasets library combines the results
to create a final dataset with keys for 'train', 'test', and 'validation'.
