What Is Bag of Words?【Explanation for Children】

Bag of Words is a method of treating text as a “set of words.”

For example, the sentence “The dog is cute” is:

• “dog”: once
• “is”: once
• “cute”: once

By simply counting them this way, word order does not matter. Because it is easy to understand, it is used for basic text analysis.
