Re: [?? Probable Spam] 答复: kMeans

Carrot2 is for clustering web search results -- it's not exactly the same thing.

Hi Marko,

I don't think it's an acceptable project for Mahout -- Mahout goals are in large 
data set processing, supported by Map-Reduce. Clustering search results is 
usually in-memory, on-line clustering with few information sources (titles, 
snippets) and the resulting high noise.

That said, what I envisage could be done is to work on data structures that 
could _support_ sensible on-line faceting/clustering of search results, 
similarly to what Google supposedly does behind the scenes to reorder search 
results (similar concept clustering). Building semantic relationships between 
terms or detecting frequently recurring phrases with significantly different 
meanings is definitely interesting and challenging (if not done naively), 
especially on large scale.
