In the era of Internet-based services, companies increasingly use Web technologies to interact. Due to the inherent heterogeneity both at data and process level, ensuring interoperability between Information Systems is difficult. To automate electronic exchanges between businesses, the classical approach is to follow strictly at runtime a common interacting protocol that must be defined beforehand...
Security vulnerabilities play an increasing role within dependability procedures for information systems. However, traditional vulnerability models present several general shortcomings when matched with today requirements. To overcome these limits, we propose a vulnerability ontology based on three main enhancements: deeper integration with system asset ontology, better modelling of cause-effect relationships,...
The paper focuses on emergent systems, i.e., complex systems for which it is impossible to foresee the overall system's behavior from the composition/interaction of the single functions/services performed by its components. The lack of knowledge on some aspects of the system, which is the source of the emergence, is an unavoidable aspect that should be explicitly taken into account in all the phases...
Monitoring activities of daily living is one of the key functionalities expected from a Smart Living environment providing independent living services for elderly people. Simple state-change sensors have been considered to be a promising sensing technique to observe the environment and consequently provide the data required to form the basis to infer high-level behaviours. From a data analysis point...
