The paper seems very similar in principle to LSA. What you need for a
concept vector (or position) is the application of LSA followed by K-Means
which will give you your concept clusters.
I would not knock Hutter too much. After all LSA reduces {primavera,
mamanthal, salsa, resorte} to one word giving 2 bits saving on Hutter.
