All parts of Text Analysis in Q5 (Video)
The initial stage of most text analyses is to do some pre-processing of the text, which includes breaking the text up into separate words and doing some basic cleaning. These steps are performed by Create > Text Analysis > Setup Text Analysis. This creates an output in the Report which can then be used as an input to the other analyses from the Techniques section of the menu. The text processing is designed to be used with English-language text.
