Design Goals 1. Accuracy • Recommendation algorithm must accurately reflect user preferences
• Data must be comprehensive and error-‐free 2. Ease of Use • Must be powerful enough to be worth using • Must be simple enough for Grandma
3. Transparency • Recommendations should not be a black box – users need to understand why products were recommended
4. Scalability and Modularity • It should be easy to add new product types and data sources
• Today: TV recommendations, Newegg data • Tomorrow: Laptop and cell phone recommendations, Amazon and BestBuy data
