M.S. Paper Title: Part of Speech Induction using Non-negative Matrix
Factorization

Abstract:
Unsupervised part-of-speech induction involves the discovery of
syntactic categories in a text, given no additional information other
than the text itself. One requirement of an induction system is the
ability to handle multiple categories for each word, in order to deal
with word sense ambiguity. We construct an algorithm for unsupervised
part-of-speech induction, treating the problem as one of soft
clustering. The key technical component of the algorithm is the
application of the recently developed technique of non-negative matrix
factorization to the task of category discovery, using word contexts
and morphology as syntactic cues.
