“Text analysis tools aide the interpreter asking questions of electronic texts”
You can use text analysis tools to automatically extract information from a text or a collection of texts. The tools can help you get a different view of a text, to generate or test hypoteses, to compare two or more texts.
Text analysis tools will let you extract quantitative information about texts, automatically compare and contrast texts, identify and extract information from texts and much more. There are different kinds of tools. Some can be used via an online interface, others can be installed locally on your computer.
If you have a text, for example retrieved from a database like LION, you can run that through a text analysis tool and get information or see patterns that may otherwise be difficult to spot.
Concordance tools - search for a word or phrase and see all instances in your text, displayed with a limited amount of context
