Personalized Context-Aware Point of Interest Recommendation [article]

Mohammad Aliannejadi, Fabio Crestani
2018 arXiv   pre-print
Personalized recommendation of Points of Interest (POIs) plays a key role in satisfying users on Location-Based Social Networks (LBSNs).  ...  We investigate four approaches to use our proposed mapping for addressing the data sparsity problem: one model to reduce the dimensionality of location taste keywords and three models to predict user tags  ...  For UT-ML, instead of the keyword boosting score (S boost ), we use the score based on the predicted user tags following maximum likelihood criterion.  ...

GeoSRS: A hybrid social recommender system for geolocated data

Joan Capdevila, Marta Arias, Argimiro Arratia
2016 Information Systems  
We present GeoSRS, a hybrid recommender system for a popular locationbased social network (LBSN), in which users are able to write short reviews on the places of interest they visit.  ...  Finally, we study the performance of GeoSRS on our collected dataset and conclude that by combining sentiment analysis and text modelling, GeoSRS generates more accurate recommendations.  ...  A good deal of researchers have been combining multiple recommendation techniques to boost the performance of the so-called hybrid systems (Burke, 2002) .  ...
