citromatik,
How often are these titles changing? How important is it to get "this article belongs to this cluster" right? How "tight" are the clusters - these articles all talk about social networking sites vs these articles all have to do with lawsuits against Facebook? I have lots of ideas but it all depends on knowing more about your goals.

See for instance Efficient Fuzzy Matching Of An Address. In working through that problem I ran down a number of dead ends which might be just right for you.

Cheers - L~R
