We apply topic modelling to automatically induce word senses of a target word, and demonstrate that our word sense induction method can be used to automatically de- tect words with emergent novel senses, as well as token occurrences of those senses. We start by exploring the utility of stan- dard topic models for word sense induction (WSI), with a pre-determined number of topics (=senses). We next demonstrate that a non-parametric formulation that learns an appropriate number of senses per word ac- tually performs better at the WSI task. We go on to establish state-of-the-art results over two WSI datasets, and apply the pro- posed model to a novel sense detection task.
