Welcome to Klatsch! (Version 1.0 -- written 9/2010 by Mark Meiss) What is Klatsch? The purpose of the Klatsch framework is to provide an easy-to-program, flexible interface for exploring and analyzing feeds of social media data. It's meant to be easy to interface to existing algorithms and graph representations and to produce pretty pictures in a variety of formats. The language itself is somewhere between Python and Scheme: dynamic types, procedures as first-class data, call-by-value semantics, and a nod toward object orientation. Klatsch is built around a scripting language implemented by an interpreter written in Java. You don’t need to know how to program Java in order to develop Klatsch scripts; that’s only necessary if you want to extend or modify the interpreter itself.
