You give the user a list of recommended articles, but don't describe any means of determining whether those articles are actually useful to the user or not. It seems most of the data would be unlabeled here, for which there is no concept of accuracy, precision, or recall - you can't know what proportion of the relevant items you found without knowing the relevance of every individual item. | |

| Jun 16, 2016 at 23:20 | comment | added | jeff | I see. then the number of false negatives should be the ones you returned but not in the user's library, which is not necessarily 0. right? | |
| Jun 16, 2016 at 22:24 | comment | added | Roy C | @HalilPazarlama I guess a more appropriate definition for precision and recall for recommender systems would be, precision = (# of recommendations in the user's library)/(total number of recommendations), recall = (# of recommendations in the user's library)/(# of articles in the library). | |
| Jun 16, 2016 at 22:18 | comment | added | jeff | It depends on your definition of true positive (i.e. a successful guess), hence your performance measure. this and this might be related. | |
