+## ⚽ AI21-WorldCup dataset
 The **AI21-WorldCup** dataset consists of 22 Wikipedia pages, each corresponding to one WorldCup tournament held between 1930 and 2022,

 To increase the difficulty, the main statistics table was removed from each document.
 Because there are only 22 tournaments in total, the dataset is provided as a single collection without separate training and evaluation splits.
