JUNG — the Java Universal Network/Graph Framework--is a software library that provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. It is written in Java, which allows JUNG-based applications to make use of the extensive built-in capabilities of the Java API, as well as those of other existing third-party Java libraries.
The PDF Renderer is just what the name implies: an open source, all Java library which renders PDF documents to the screen using Java2D. Typically this means drawing into a Swing panel, but it could also draw to other Graphics2D implementations. We hope you will come up with cool things to do with it that we never thought of.
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.
