The definition of a token from stanford, a token is an instance of a sequence of characters in some particular document that are grouped together as a useful semantic unit for processing. we will be using trump's remarks about leaving the walter reed medical center as the. The unnest tokens function seems like it already handles the edge case of starting and ending with the pattern. Any elegant solution different from tidytext::unnest_tokens would be accepted! In the tidytext package, there is a function unnest_tokens which has this functionality; Tokens are mentioned a lot in text mining. Index tidy.documenttermmatrix (tdm_tidiers), 12 tidy.lda. Tidytext contains a function called unnest_tokens. Then we can use unnest_tokens() together with some dplyr verbs to find the most commonly used words in each. Perhaps a bigger issue is that unnest_tokens already does lots of things in a robust way, whereas stringr is more generic which means other things need to be considered.
