Software

TikZ-dependency allows you to draw dependency graphs in LaTeX documents with little or no effort. It also comes with a lot of styling facilities, to let you personalize the look and feel of the graphs at your liking.

FLinK stands for “a framework for the linearization of kernel functions”.

The software has been developed as part of my PhD to support our research on the linearization of kernel functions, whose main results so far are published in the following papers authored by me with my co-advisor Alessandro Moschitti:

• On Reverse Feature Engineering of Syntactic Tree Kernels (CoNLL 2010, [1])
• Reverse Engineering of Tree Kernel Feature Spaces (EMNLP 2009, [2])
• Efficient Linearization of Tree Kernel Functions (CoNLL 2009, [3])

(My thesis contains more in-depth information, but I didn’t make it public yet because I am still fixing things here and there).

Although it could possibly be estended to support a large variety of kernel functions, at the moment the framework only supports the Syntactic Tree Kernel [Collins and Duffy, 2001] and the Partial Tree Kernel [Moschitti, 2006].

SVM-Light-TK by Alessandro Moschitti is used for learning and classification in Tree Kernel spaces.

For more information about the linearization process, please refer to the aforementioned papers. More details, as well as comprehensive documentation of the user interface and the programmer API can be found here.
