21 Text Mining

20190221 Text Mining (or Text Analytics) applies analytic tools to learn from collections of text data, like social media, books, newspapers, emails, etc. The goal can be considered to be similar to humans learning by reading such material. However, using automated algorithms we can learn from massive amounts of text, very much more than a human can. The material could consist of millions of newspaper articles to perhaps summarise the main themes and to identify those that are of most interest to particular people. Or we might be monitoring twitter feeds to identify emerging topics that we might need to act upon, as it emerges.
