Text analytics is basically a way to perform quantitative analysis on qualitative information stored in text. In this recipe, we will create a corpus of documents from PDF files and perform descriptive analytics on them, looking for the most frequent terms.
This is a particularly useful recipe for professionals who work with PDF reports.
