Hello
I have got a project in which I have to extract keywords given a URL. I would
like to know methods for extraction of keywords. Frequency of occurence is one;
but it seems naive. I would prefer something more robust. Please suggest.

I'm certainly not going to argue against that, I just don't find the

Howdy,
I'm a long time python user but ran across something I have never needed to do
before and don't know how to do it.
The issue is that I need for my python script to call some matlab routines.
Matlab is very expensive to start running, so I only want to run it once. I also
want the changes
