Re: Count Ouccrence of words in a long text

Hi Yako

You will get a variety of responses to this question (we all love
one-liners), but this is my 2 cents worth.

One minute in the Help and I came up with:

text = "Hello, 
 First of all I am pretty new to Mathematica, so excuse me if this has
 a simple answer. 
 What I need is to be able to count the occurrence of each word of a
 text and count the times each word appears on it. I know how to do
 this on other languages but I am trying to achieve it with
 Mathematica. 
 Can someone hint me the way to go? 
 Thanks!";

StringSplit[ text] // Tally // Grid

or

StringSplit[ text] // Tally // Sort // Grid

to get the words in alphabetical order, or

Map[ Reverse, StringSplit[ text] // Tally ] // Sort // Grid

to get the words in order of increasing frequency, or

Reverse[ Map[ Reverse, StringSplit[ text] // Tally ] // Sort ] // Grid

to get the words in order of decreasing frequency.

I.e., using your email text as the example text, StringSplit (by
default) splits at spaces, and well, Tally is a *great* command for all
sorts of applications.

The sky*s the limit.

Cheers

Barrie
