Social Tagging and Folksonomy in Recommendation Systems: Models, Algorithms, and Applications

This article surveys the role of social tagging (folksonomy) in modern recommendation systems, describing how user‑generated tags form a three‑dimensional "tag cube" that can be combined with rating matrices, and reviewing a range of algorithms—including neighbor‑based, ranking (FolkRank/SocialRank), content‑based, linear regression, and matrix‑factorization approaches—while also discussing tag selection, noise handling, and scalability challenges.
