With this practical book, you’ll explore text-mining techniques with tidytext, a package that authors Julia Silge and David Robinson developed using the tidy principles behind R packages like ggraph and dplyr. You’ll learn how tidytext and other tidy tools in R can make text analysis easier and more effective. csv, pdf) into a raw text corpus in R. The steps string operations and preprocessing cover techniques for manipulating raw texts and processing them into tokens (i.e., units of text, such as words or word stems). The tokens are then used for creating the document-term matrix (DTM), which is a common Text Mining Handbook Casualty Actuarial Society E-Forum, Spring 2010 2 We hope to make it easier for potential users to employ Perl and/or R for insurance text mining projects by illustrating their application to insurance problems with detailed information on the code and functions needed to perform the different text mining tasks.
