Semantics-based recommendation technology has recently received a lot of attention in information services community.Compared with traditional recommendation algorithms
semantics-based recommendation algorithms have the marked advantages in the aspects of real-timing
robustness and recommendation quality.From the status and progress of domestic and foreign research
we summarize the following four aspects:semantics-based content recommendation algorithms
and semantics-based social recommendation algorithms.And this paper is expected to provide a worthwhile reference for relevant researchers by detailedly analyzing semantics-based recommendation algorithms.Finally
we show readers the challenges and future research directions in this field.
