What We Will Do

• Let business know which parts need to care more(business-driven)

• Add and rank tags on each review (e.g., taste, hygiene)

• Classify top 10 and worst 10 frequently show up keywords

• Distinguish the review based on the users

Tuesday, November 26, 2013

Why We Want to Do It

• Business can get the opinion from users from the reviews, without questionary usage

• Review’s rating is not specific, and the rating is subjective

• There lies a lot of hidden information within the reviews

• The classified data (result data) may had further improvement
