Data in text format is converted to numerical values (or vectors) by text processing, so that these vectors may be given to the machine as input and analysed with the algebraic principles. However, there's a chance of data loss if we go through with the transition. The idea is to strike a balance between data conversion and data retention.  Preprocessing of text is necessary before processing the text. Text processing techniques will be discussed in this article.
