Title
Body
I need to find naturally occurring classes of nouns based on their distribution with different preposition (like agentive, instrumental, time, place etc.). I tried using k-means clustering but of less help, it didn't work well, there was a lot of overlap over the classes that I was looking for (probably because of non-globular shape of classes and random initialisation in k-means). I am now working on using DBSCAN, but I have trouble understanding the epsilon value and mini-points value in this clustering algorithm. Can I use random values or do I need to compute them. Can anybody help? Particularly with epsilon, at least how to compute it if I need to?
