Toward Service Recommendation in Internet of Things

Internet of Things (IoT) is the next wave of industry revolution that generates signifieant amount of various serviees, such as personal health care and green energy monitoring, which people may subscribe for their convenience. These services may have different features, such as fixed or mobile, scalable or non-scalable, portable or non-portable. Thus, recommending IoT services to users based on objects they own will become very important for the success of loT. In this preliminary work, we introduce the concept of service recommender systems in loT by a formal model for IoT recommendation. We propose a graph-based recommender system that takes into account the unique structure of IoT.
