At this stage I feel pushed more by exploration and curiosity than a precise strategy. I know where I have to go and which point I have to reach, but on the exact path to take things are still uncertain. Now I can see a couple of options:

step zero -> Computing the semantic distance matrix using Latent Semantic Indexing.

1. Using this matrix to sparsify the gabriel graph of the geographic layer;

2. Merging the semantic and the geometrical matrix to be used in an ad-hoc clustering algorithm;

3. Computing the semantic or geometric clustering and apply the other matrix to mining the results.
