Consequently, methodologies need to be developed that assist us in living a healthier life. In this chapter, we present a health assistance system for immigrants. The system consists of two parts: A health information system that allows users to search for health information using natural language queries composed of multiple languages and a prevention service that assists users in their cooking routine and motivates them to perform frequent physical exercises. The information system uses NLP techniques to understand the user query, matches it to a health ontology we developed, and offers the user a comprehensive answer. The prevention service is embedded in a smart home environment. We present the technical details of both systems and show a user study to demonstrate that the system works well in providing highly relevant health information.en000 Informatik, Informationswissenschaft, allgemeine Werkeontologieshealth assistantimmigrantshealth information systemprevention serviceBook Part2191-6594
