What is stemmed?

Stemming is a process that involves converting a word or phrase to its base or stem form. For example, the stem for the words "jogging," "jogged," and "jogs" is "jog." The goal of stemming is to reduce words to their core meaning so that they can be more easily analyzed and compared. Stemming is often used in natural language processing and text analysis applications, such as search engines and spam filters. However, stemming is not perfect and may sometimes produce incorrect results or fail to take into account nuances in meaning.
