What does "Stop Words" mean?

Table of Contents

Stop words are common words that are usually ignored in text analysis. These words include "the," "is," "in," and "at." They are often so frequent that they do not add much meaning to the overall message.

In text processing, removing stop words helps focus on the more important words that contribute to the meaning of the text. By skipping these common words, it becomes easier to analyze and understand the main ideas.

For example, in a sentence like "The cat is on the mat," we might ignore "the," "is," and "on" to better highlight the key words "cat" and "mat." When analyzing large amounts of text, managing stop words can improve the efficiency and accuracy of various tasks, like creating word embeddings or training tokenizers.
