Conclusiones and Open Trends

This book covers new advances on recommender systems for the Social Web. The contributed chapters look through general aspects related to recommenders, their legal effects, the problem of interoperability and the social influence for recommendation (trust and groups). Finally, two differentes applications of social recommendation are also shown. This chapter include the authors’ view about the open trends and the future of recommendation. Specifically, we understand the current research lines might be ascribed to the following areas (i) the application of data-mining and SNA (Social Network Analysis) to obtain a Social Aggregation Model; (ii) the need for integrating different models and data structures to make interoperability in the Social Web feasible; and (iii) no matter how recommender systems will improve their precision and recall, its deployment must face with and find their natural arrangement in cloud computing environments.
