Formula 2 and 3 cover for a specific application, which is
measuring the customer probability attraction to our product.
For example, a specific product definition explains that the
product is suitable for teenager who likes to surf the Internet at
night. Thus the information collected from the social media to
find a prospective customer is for a customer that age between
10 to 17 years old and their status update in social media
mostly between 6 p.m. to 10 p.m. This information then can be
used to advertise the product at that period of time and to the
specific teenager customers.
