I remove the old one. New one is [here](https://www.slideshare.net/changecandy/recsys19-smore). If you'd like to see the old one, send me a mail.

In current stage, hoprec requires inputing a .txt file specifying the which vertex is user/item like: ``` userA u userB u userC u itemA i itemB i itemC i itemD...

both dot product and cosine similarity are okay

yes, such vector-based retrieval is able to achieve a reasonable performance
