Our proposed ranking model ranks conversation partners based on self-reported rapport levels for each participant. The is important tasks that recommend interaction user built in past interactions, such as matchmaking between a student and teacher one-to-one online language classes. To rank partners, we can use regression predicts ratings. It is, however, challenging to learn the mapping from p...

I investigate this question using a novel data set from Charity Navigator which provides quality ratings for 5400 charities.

Sunni Islam has no supreme legal authority and disagreement by doctors of Islamic law over all issues not clarified by Islamic law is physiological. This is the case with Medically Assisted Reproduction: after an initially critical attitude, tolerance, limited exclusively to homologous practices, is spreading, whilst recourse to heterologous practices is considered on a par with adultery or for...
