Retraction notice

The journal retracts the article “Next Point of Interest (POI) Recommendation System Driven by User Probabilistic Preferences and Temporal Regularities” [1].

Following publication, concerns were brought to the attention of the Editorial Office regarding an overlap with a previously published paper [2], produced by a different authorship group.

Adhering to our complaints procedure, an investigation was conducted by the Editorial Office and Editorial Board which confirmed a significant similarity in concept and methodology with an earlier publication [2], without appropriate acknowledgement or citation. As a result, the Editorial Board decided to retract this article as per MDPI’s retraction policy (MDPI|Research and Publication Ethics).

This retraction was approved by the Editor-in-Chief of the journal Mathematics.

The authors agree to this retraction.
