Collection of data with a common format and goal-relevant content. Ideally, the data selected in this way represents the larger data set or the assumed real characteristics.

Note: Datasets can be used for training, validation and testing of an AI model. In the context of machine learning, datasets serve as the basis for training a machine learning algorithm.

Example 1: Microblogging posts from June 2020 linked to the hashtags #rugby and #football.

Example 2: Macro photos of flowers with size 256x256 pixels.
