Intro to Unstructured Data

Good short piece on the increasingly important topic, by Radhika Subramanian.   The article also points to a free eBook on the topic.  Have not looked at that yet.   Its also important to understand two conundrums on this. One is that text is not the only unstructured data.  And second, that text has structure, notable from the increasing amount of natural language processing being used.  Language contains structure.
