Robin Good's insight:

Overview is a new free tool designed for investigative journalists and researchers interested in finding relevant information within large collections of text documents, from reports to social media tweets.

Overview greatly simplifies the task of analyzing, indexing and visualising large document collections in ways that can allow a journalist to identify relevant patterns and threads across thousands of different documents.

Overview is an open-source document mining system which allows you to upload thousands of documents either in PDF format, via theDocumentCloud or through a CSV spreadsheet file. These documents can be rapidly indexed, sorted and analyzed in order to present an organized visual overview of their contents. 

"Whether you are a journalist starting with thousands of pages of government documents, a reasearcher facing a huge archive, or a social media analyst starting with 100,000 posts, Overview will organize your documents into topics and sub-topics, and then visualize them -- so you can find exactly what you're looking for, instantly count the number of documents in each topic, or tag entire topics for further work."

Free to use. Open-source.
