A Location Recommendation Model Based on User Behavior and Sequence Influence

There are evident sequential patterns in human visits to different locations in daily life, which has led to the emergence of numerous sequence-based geographic location recommendation methods. However, previous research has mainly focused on considering the sequential patterns of check-ins as a whole, while overlooking the fact that users’ interactive behaviors at check-in locations are likely to influence their preferences for those locations, and subsequently impact their future check-in decisions. The problem of how to fully leverage a user’s overall location sequence and location interaction data to provide more personalized recommendations is still unresolved. To address this issue, we propose a geographic location recommendation model called UBSI (User Behavior and Sequence Influence) in this article. Our model is constructed based on check-in sequence, weight model, collaborative filtering, and \(n\) th-order additive Markov chain. First, UBSI collects users’ check-in sequence and interaction behavior data, generates interest weight using a weight model, integrates personalized data using collaborative filtering method, and finally applies the weighted \(n\) th-order additive Markov chain to mine sequential pattern of user check-ins for location recommendations. Finally, we conducted extensive experiments to demonstrate the effectiveness of our approach. The experimental results indicate that our UBSI solution can effectively improve the accuracy of recommendations.
