Recommendation System (RS) has played a significant role recently, especially with the growth of information and the development of the Internet worldwide. Due to issues with the recommendation algorithms, new data sources are required. The Social Network (SN) growth has stimulated its use in several areas, including RSs, leading to the social recommendation systems appearance (RS based on SN). Most studies in this field emphasize recommendation algorithms while ignoring the value of social network data and its impacts on the quality of recommendations. This review paper provides an overview of the techniques used to extract information from the social network for enhancing user representation as well as can be regarded as a reference to social recommendation systems in terms of datasets, algorithms, and evaluation metrics.
