Research Article Recommender Systems: A Comprehensive Review of Models, Approaches and Evaluation Metrics

With the advent of the current digital era, individuals across the developed world are commonly equipped with devices that can access vast amounts of information at their fingertips. What was considered an impossible feat was realized through remarkable technological advancements. This positive transformation has had a profound impact on education, where traditional knowledge management, such as libraries, are no longer a primary determinant of a student’s academic success. Instead, it has been replaced by the internet as a medium for learning, practicing, and topic exploration. However, the sheer volume of the ever-increasing information available online can easily overwhelm a user, particularly when conducting detailed research on a specific topic. Therefore, the need for a reliable research article recommender system cannot be understated, helping students and researchers to navigate the expansive knowledge space better and achieve their learning and research objectives. This review paper aims to study the most common types of recommendation system techniques in research articles recommender systems (RS). A total of ten related works and relevant evaluation metrics written by other researchers will be studied and accessed rigorously using comparative analysis, granting further insights into the current work similar or related to the domain of this paper. Finally, this paper will identify and elaborate their current trends and gaps in the discussion section.
