Hi ,

I am trying to find a algorithm to see similar sentences.  
Here using MLT, i can see if Document X matches 70% of Document Y  
But then if Document X is a small sentence and Document Y is a very big one  
, still X is matched again Y.

Here instead of just seeing 70% of X matching Y , i also want to see if 70%  
of Y matching X.

To quote an example -

The sentence "world is big" will match against "The whole world is a big  
place to be" with MLT 100% similarity.  
But "world is big" is not actually a variant of  
the aforementioned sentence.

Here how can i solve the issue ?
