Requirement analysis of Ubiquitous Intelligence System for personal diet formulation and maintenance

Nutrition Related Diseases (NRD) are globally widespread causing substantial economic cost for governments and individuals. Formulating and maintaining a balanced diet meeting the Recommended Dietary Intake (RDI) is complex, time consuming task. The detailed analysis conducted in this study reveals many intellectual tasks involved in meals scheduling and diet formulation. This study reports the results of requirement analysis of a Ubiquitous Intelligence System for automating the diet formulation, monitoring and maintenance. The authors propose Dietary Intelligence System (DIligenS) that applies computational intelligence and has the architectural components of knowledge base, inference engine, data base and data extraction and conversion modules in addition to the knowledge building and application interface.
