Both the Myers-Briggs corpus used on typealyzer.com and the mood corpus used at uClassify are now available on my Github account. They both concist of example texts for each dimension I selected manually from the web based on pretty extensive reading about C.G. Jungs type theory, Myers-Briggs and Naomi Quencks book about how stress plays out differently in people depending on their personality type.
I've since I made these corpora explored several other psychological theories, but more importantly learned how to code in order to improve the process for creating psychological text analysis. You can find out more about what I'm up to right now by watching these slides.
