Text mining, or digital text analysis, is the process of using digital tools to search for, extract and analyse text data.
«Text mining or text analytics is an umbrella term describing a range of techniques that seek to extract useful information from document collections through the identification and exploration of interesting patterns in the unstructured textual data of various types of documents – such as books, web pages, emails, reports or product descriptions.» (Truyens & van Eecke, 2014)
Why text mining? Automated search strategies can provide an overview of patterns and tendencies in large volumes of text. This may provide insight that would otherwise be difficult to achieve, time-consuming or both through conventional qualitative methods.
