《Mahout in Action》中对content-based推荐技术的评价

2019独角兽企业重金招聘Python工程师标准>>>

There’s nothing wrong with these techniques( content-based,本人注 ); on the contrary, they can work quite well. They are  necessarily domain - specific approaches, and would be hard to meaningfully codify into a framework. To  build an effective content -based book recommender, one would have to decide which attributes of a  book  --   page count, author, publisher, color, font  --   are meaningful, and to what degree. None of this  knowledge translates into any other domain; recommending books  this way doesn’t help in recommend  pizza toppings. 

For this reason, Mahout will not have much to say about this sort of recommendation. 

写的不错，对吧~^^
