Dynamic discovery of favorite locations in spatio-temporal social networks

作者:

Highlights:

• An original framework of semi-supervised learning is presented for POI recommendation.

• Multiple factors are jointly studied to excavate complex spatio-temporal patterns of visiting behaviors.

• A network embedding method is proposed to learn the vectors of users and POIs in an embedding space with low dimensionality.

• A dynamic factor graph model is proposed to model different factors including the correlation of users’ vectors and POIs’ vectors.
