In this paper, we describe a model that learns seman-
tic representations from the distributional statistics of
language. This model, however, goes beyond the com-
mon bag-of-words paradigm, and infers semantic repre-
sentations by taking into account the inherent sequential
nature of linguistic data. The model we describe, and
which we refer to as a Hidden Markov Topics model is
a natural extension of the current state of the art in
Bayesian bag-of-words models, i.e. the Topics model of
Griffiths, Steyvers, and Tenenbaum (2007), preserving
