Evolution of the users’ participation to the semantic communities during Occupy Wall Street Movement.

<p>On the left end we have the hashtags used in the communities in the first phase of the movement; on the right end we have the same at the end of the movement. Connecting lines represent the flows of users whose interests in the discussion have changed during the period of the movement as represented from the different types of hashtags they use (i.e. users using hashtags in community <i>i</i> at the beginning and in community <i>j</i> at the end).
