    I created a macro-enabled Microsoft Word document which allows user to highlight text span with one-click. The document is being used for annotation tasks in our group. My document is compatiable with Microsft Word 2010 or newer. The file has ribbon menu customized using Microsoft Office 2007 Custom UI Editor.

    I programmed this plug-in classifier for Weka, which simply calculates inter-rater agreement, e.g. accuracy, kappa. The input (.CSV format) has two columns representing labels annotated by two raters.

    I find LightSide an useful software for text classification experiments. The software helps extract n-grams, production rules, dependency relations, and more. User can also add column features which are extracted indepdently.

    For a lightweight and fast LDA implementation, I use GibbsLDA++.

    pyDev is a must-have IDE for Python programmers who use Eclipse.

    You may find these LaTeX CV-templates helpful.
