μ Item-to-Item Correlation Recommendation.- userPref is a set of book preferences of a user.
- For every meaningful action(searching, viewing, writing a review, rating without writing reviews) there is a pref coefficient. (prefCoef)
- bookPref is a set of book preferences of a book. (similar concept to "also bought")
- When a user does a specific well-defined action, bookPref is updated as "prefCoef*userPref+bookPref" and resorted. (some books at the end of the list might be eliminated for performance reasons)
