>From Amateurs to Connoisseurs: Modeling the Evolution of User Expertise
through Online Reviews<http://cs.stanford.edu/people/jure/pubs/beerrec-www13.pdf>by
J. McAuley, J. Leskovec.
*ACM International Conference on World Wide Web (WWW)*, 2013

Here is abstract:

*Recommending products to consumers means not only understand-
ing their tastes, but also understanding their level of experience.
For example, it would be a mistake to recommend the iconic film
Seven Samurai simply because a user enjoys other action movies;
rather, we might conclude that they will eventually enjoy it—once
they are ready. The same is true for beers, wines, gourmet foods—
or any products where users have acquired tastes: the ‘best’ prod-
ucts may not be the most ‘accessible’. Thus our goal in this pa-
per is to recommend products that a user will enjoy now, while
acknowledging that their tastes may have changed over time, and
may change again in the future. We model how tastes change due
to the very act of consuming more products—in other words, as
users become more experienced. We develop a latent factor rec-
ommendation system that explicitly accounts for each user’s level
of experience. We find that such a model not only leads to better
recommendations, but also allows us to study the role of user expe-
rience and expertise on a novel dataset of fifteen million beer, wine,
food, and movie reviews.
