It’s extra restricted as a result of it solely accommodates datasets that individuals have printed with Kaggle. But it surely’s extra targeted as a result of the datasets aren’t simply no matter random set of numbers Google scraped. Kaggle is a house for information science competitions, so the datasets it collects are extraordinarily related to information science.
