Analysing the comments for products (woocommerce)

WordPress Information :
Version: 4.6.3
Theme: Dorian

Using this site as an e-commerce store where I’ve listed a few products. The thing is I want to be able to analyse the comment and display the result on the particular product page when it is submitted. I have my analysis code with me, I just need to know where and how I should add it to the site. Don’t really want to break the site.

Any help will be appreciated. Many thanks in advance.
