Models of category learning have been ex- tensively studied in cognitive science and primarily tested on perceptual abstractions or artificial stimuli. In this paper we focus on categories acquired from natural lan- guage stimuli, that is words (e.g., chair is a member of the FURNITURE category). We present a Bayesian model which, un- like previous work, learns both categories and their features in a single process. Our model employs particle filters, a sequential Monte Carlo method commonly used for approximate probabilistic inference in an incremental setting. Comparison against a state-of-the-art graph-based approach re- veals that our model learns qualitatively better categories and demonstrates cogni- tive plausibility during learning.
