mahout 推荐器增加输入参数

Question

I need to build recommender with UserId,ItemId,Preference,Duration as input where Duration is the time(Time the user viewed the page). Already i build itembased and userbased recommender with userid,itemid,preference as input. So i need to increase the input parameter which affects the recommendation.

For example- 1012,112,4.0,3.45 is my input.

where 1012 is userid 112 is itemid 4.0 is preference 3.45 is duration

Thanks for the guidance in advance.
