Any GURU help for "related news" script

Dear all,

Greeding from Thailand. Need help for my news script. I am trying to display news which keywords match the current page keywords. I am using Dreamweaver 8 and PhpMyAdmin to manage MySQL. May I explain you what I have done. My database and data in that look like this.
