unitjava(金币+5, 翻译EPI+1): 感谢,用sorting还是ranking? 2011-11-26 19:33:03
After adding the characteristic information of “food requirements”, it acted on sorting the searching results. Then, adding the characteristic information of “medical records in recent one month”, the system would filter out the searching results which was not suitable for the user. Therefore, the recall ratio was lower than that of the pure key words.
