Here’s a workflow that uses simple preprocessing for creating tokens from documents. First, it applies lowercase, then splits text into words, and finally, it removes frequent stopwords. Text mining usually involves the process of transforming unstructured textual data into a structured representation by analyzing the patterns derived from text. The results can be analyzed to discover interesting information, some of which would only be found by a human carefully reading and analyzing the text.
