* ###special notes###
* 1. prediction for all user, please set:
* data.testset.path = poi/Gowalla/checkin/Gowalla_test.txt
* and delete the para setting for "rec.limit.userNum" in rankgeofm.properties
*
* 2. prediction for small user set like userids in [0, 100],
* in rankgeofm.properties, please set:
* data.testset.path = poi/Gowalla/checkin/testDataFor101users.txt
* rec.limit.userNum = 101
* In EntropyEvaluator and NoveltyEvaluator, you also need to reset the variable "numUsers" = your limited userNum
USGRecommender 里注释这几个 properties 应该写错了,应该是 usg-test.properties
