We propose a bootstrapping algorithm which successfully resolves two fundamental tasks: morphology acquisition and the acquisition of a subset of functional words. Given the outputs of these fundamental tasks, we build a nearly state-of-art morphology analyzer performing with a F1-score of 80.94%; also, we can improve the baseline model for acquiring functional words by an absolute error reduct...
