Learn about different types of irrelevant text data.
Introduction
Irrelevant text data refers to words, phrases, or sentences in the larger text context that are unimportant during analysis. This makes dealing with irrelevant text data an essential step in text preprocessing. It can improve the accuracy and efficiency of NLP tasks, such as sentiment analysis, topic modeling, and document classification. In the following sections, we’ll look at some examples of irrelevant text data and how to remove them using various NLP libraries.
