Recommendation systems; decision-making; health care system; expert system; fuzzy relational compositions.

The introduction of recommendation systems for the health sector has opened additional channels to improve the decision-making of physicians and administrators of the health care system. Web-based and mobile applications, social networks and virtual communities could improve these processes. The Internet provides a huge amount of information; therefore, the creation of intelligent mechanisms and tools, such as the ones proposed, allows doctors and the health sector to be better informed and improve communication channels in the decision-making process. In this work, a theoretical framework for the design and implementation of the so-called project MedicGate, a smart social network to optimize medical decisions is presented. The expectation is that this initiative will have an impact on those responsible for the generation of health policies, by providing information and resources for decision-making through informed knowledge and feedback from the medical and academic sectors.
