In recent times, the recommender system (RS) has played a significant role in assisting users in selecting the ideal product from a huge amount of data. The gradually increasing amount of customers, services and online information due to yielding the large data analysis can be a problem for service RSs. Approaches which are greatly successful cover a wide variety of recommendation tasks such as video, music, image, books. The recommendation algorithms require a variety of parameters to propose suggestions for new users, and this is where limitations and challenges of the RSs emerge. Recommendation algorithms for unstructured big data and their challenges are discussed in this chapter.
