vector space model algorithm in Java to get the similarity score between two people

Question

Hello all,

I am trying to use/implement a vector space model algorithm in Java to get the similarity score between two people based on its keywords. So I have the following classes:

Person - Has a List of keywords;

Keyword - String text; Integer score;

The keyword score is the number of mentions the person has made to the keyword.

Any suggestions on how to implement this in Java?

Regards
