Neighborhood Troubles: On the Value of User Pre-Filtering To Speed Up and Enhance Recommendations
[article]
2018
arXiv
pre-print
In this paper, we present work-in-progress on applying user pre-filtering to speed up and enhance recommendations based on Collaborative Filtering. ...
We propose to pre-filter users in order to extract a smaller set of candidate neighbors, who exhibit a high number of overlapping entities and to compute the final user similarities based on this set. ...
The authors would like to thank the Social Computing research area of the Know-Center GmbH and the AFEL consortium for their support. ...
