This might be one of the research direction to where the topic of my thesis can lead me. Different problem can emerge from this approach:

defining the semantic similarities of different messages, maybe using a markov model; categorise and tag each message to correspond to a spatial/cognitive criteria; create a convergence from the folksonomies to the categories of the messages.

Two problems might be interesting:

– define the size of the cluster of aggregation

– attribute a descriptor to the cluster

NB I have to check Amy Soller work with Markov models.
