Measuring similarity of sentences

The Jaccard Index itself calculates the similarity/diversity of two sample sets.

This module measure the similarity between senteces, based on the words in common (some of the stop words are excluded).

It is build on top of the "Natural" module - library for natural language processing.

The result should be between 0 and 1.

You can find more information about the algorithm on Wikipedia
