What is Text Data Collection?

Text data collection is the process of gathering textual data from a variety of sources. In order to build intelligent applications capable of understanding human language, machine learning models need to digest large amounts of structured text data. Gathering sufficient text data is the first step in solving any language-based machine learning problem.
