Thanks Monks, for your excellent responses.

I am glad to see 'amazing ideas. I am in the process of running your code against different patterns.
Meanwhile test your code against: 

String: bookhelloworldhellohellohihellohiworldhihelloworldhihellobookpenbookpenworld

Number of Patterns:5
==========================================================
Deduce patterns:world pen, book, hi, hello
Some more rules to identify patterns. 
1.  I am not looking specifically for dictionary words. 
2.  One Pattern cannot be part of another pattern.
3.  There could be multiple answers.
4.  A Pattern may  show up only once.
5.  A Pattern may contain single character only
6.  A Pattern may contain space also.
In case of multiple answer there could be 'techniques' we can apply to obtain the possible best
such as: minimum sum of length of patterns.

Thanks,
Artist.
