**6. Conclusion**

The risk management of natural disasters becomes a necessity to take the necessary measures at the right time and in the right place and for the construction of new structures weak and resistant to natural disasters. This chapter presents a conceptual architecture based on ontology, embedded systems and Geographic Information system for the creation of a knowledge base on the phenomenon of soil-structures interaction with the connections of external agents in real time in order to fully understand, analyze and estimate this phenomenon by experts. Considering that the ontologies play a critical role to solve the problem of the heterogeneity of external and multi-source information. An Ontology of Soil-Structure Interaction With Agents External (OSSIWAE) was proposed for managing and integrating the data coming from different sources of information (GIS, satellites, electronic sensors and comments from experts). To validate this architecture, a web platform was developed in the context of Internet of Things (IoT), which supports the different technologies used. Then, a case study is conducted on a prototype of a model for building a structure three-story to simulate data collection. Given the large number of mapping areas, in this chapter some sensors are installed. As a perspective we want to increase the number of sensors to capture other parameters.
