Text analytics. The term text analytics describes a set of linguistic, statistical, and machine learning techniques that model and structure the information content of textual sources for business intelligence, exploratory data analysis, research, or investigation. The term is roughly synonymous with text mining; indeed, Ronen Feldman modified a 2000 description of "text mining" in 2004 to Text Analysis is about parsing texts in order to extract machine-readable facts from them. The purpose of Text Analysis is to create structured data out of free text content.The process can be thought of as slicing and dicing heaps of unstructured, heterogeneous …

For other things, such as text analysis, you’ll almost certainly want character strings instead, and in many cases it will be required. It’s also worth noting that a lot of base R and other behavior will coerce strings to factors. This made a lot more sense in the early days of R, but is not really necessary these days.

Text mining, in general, means finding some useful, high quality information from reams of text. More specifically, text mining is machine-supported analysis of text, which uses the algorithms of data mining, machine learning and statistics, along with natural language processing, to extract useful information. A tibble is a modern class of data frame within R, available in the dplyr and tibble packages, that has a convenient print method, will not convert strings to factors, and does not use row names. Tibbles are great for use with tidy tools. Notice that this data frame containing text isn’t yet compatible with tidy text analysis, though.
