The cosine measure is well known in IR field. It is integrated to Lucene
or other search engines.
You can find its definition in every books related to IR (Modern
Information Retrieval - Baeza-Yates & Ricardo Neto-
http://people.ischool.berkeley.edu/~hearst/irbook/) and Text Data Mining.
It is really simple to implement.

You also can find some relevant Java source at

with many other similarity measures. Note that I did not test it....

Best regards,
