A simple particle system physics engine for processing. I've designed this to be application / domain agnostic. All this is supposed to do is let you make particles, apply forces and calculate the positions of particles over time in real-time. Anything else you need to handle yourself.
The boilerpipe library provides algorithms to detect and remove the surplus "clutter" (boilerplate, templates) around the main textual content of a web page.The library already provides specific strategies for common tasks (for example: news article extraction) and may also be easily extended for individual problem settings.Extracting content is very fast (milliseconds), just needs the input document (no global or site-level information required) and is usually quite accurate.Boilerpipe is a Java library written by Christian Kohlschütter. It is released under the Apache License 2.0.
