Abstract: The Increasing Trend of Group Activities Has Led to Changes in Recommender Systems, Shifting from Recommending Individual Users to Recommending Groups of Users. a Group Recommender System Consists of Two Primary Stages: Aggregating the Profiles of all Group Members to Create a Virtual User and Providing Recommendations to This Virtual User. This Paper Focuses on the Stage of Recommending the Virtual User. Specifically, Our Proposed Approach Aims to Recommend the Virtual User to Achieve a Harmonious Balance Among the Diverse Preferences of Group Members by Combining the Profiles of Group Members with that of the Virtual User. Additionally, We Integrate Textual Comments Observed from Users to Further Enhance the Accuracy of Group Recommendations. Experiments Conducted on Three Popular Datasets from Amazon Have Demonstrated the Effectiveness of the Proposed Approach in Terms of the F1-Score.
