semantic similarity search in spatial databases

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.
