Text-mining is one of many data-mining techniques that social scientists are using to turn unstructured (or more accurately, semi-unstructured) material into structured material that can be analysed statistically. In this way, researchers are gaining access to new materials and methods that were previously unavailable. As such, it is increasingly important that social scientists have a clear understanding of what text-mining is (and what is isn't) as well as how to use text-mining to achieve some basic and more advanced research outcomes.
