This document proposes a scalable content-aware collaborative filtering (ICCF) system for location recommendation that avoids negative sampling. ICCF considers user profiles, textual content, and relationships between concepts to learn user preferences. It evaluates features like dimensionality and estimate accuracy, and relates ICCF to graph Laplacian regularization. The system was evaluated on a large-scale LBSN where ICCF improved accuracy over other collaborative filtering methods by addressing data sparsity issues through an injection approach. Naive Bayes and collaborative filtering algorithms are used and the system aims to provide personalized and diverse location recommendations while preserving user privacy.
