how to group similar url using the DBSCAN algorithm. I have seen many datasets but none were on url , I want to take similar type of urls and group it together. Here i am not able to know distance (eps) and minpoints can be the number of urls to be grouped.

回答1:

DBSCAN needs a distance function and a threshold for detecting similar objects.

So go ahead, first you need to define an appropiate distance function and a threshold, then we can help you with DBSCAN (but you should be able to find DBSCAN implementations that can be extened to arbitrary distance functions).

The key challenge is the distance, and this is up to you, because we do not know what you want to get out. This is very subjective, and we just don't know what you want or need.
