Improvise Exploratory visualization based on multiple coordinated views is a rapidly growing area of information visualization. Ideally, users would be able to explore their data by switching freely between building and browsing in a flexible, integrated, interactive graphical environment that requires little or no programming skill to use. However, the possibilities for displaying data across multiple views depends on the flexibility of coordination, the expressiveness of graphical encoding, and the ability of users to comprehend the structure of their visualizations as they work. As a result, exploration has been limited in practice to a small fraction of useful visualizations. Improvise is a fully-implemented Java software architecture and user interface that enables users to build and browse highly-coordinated visualizations interactively.
4 free data tools for journalists (and snoops) - O'Reilly Radar Note: The following is an excerpt from Pete Warden’s free ebook “Where are the bodies buried on the web? Big data for journalists.” There’s been a revolution in data over the last few years, driven by an astonishing drop in the price of gathering and analyzing massive amounts of information.

Extractiv tf–idf One of the simplest ranking functions is computed by summing the tf–idf for each query term; many more sophisticated ranking functions are variants of this simple model. Motivation Suppose we have a set of English text documents and wish to determine which document is most relevant to the query "the brown cow". A simple way to start out is by eliminating documents that do not contain all three words "the", "brown", and "cow", but this still leaves many documents. However, because the term "the" is so common, this will tend to incorrectly emphasize documents which happen to use the word "the" more frequently, without giving enough weight to the more meaningful terms "brown" and "cow". Mathematical details tf–idf is the product of two statistics, term frequency and inverse document frequency. The inverse document frequency is a measure of whether the term is common or rare across all documents. with Then tf–idf is calculated as Example of tf–idf Idf is a bit more involved:
