Contracts and Behavioral Patterns for SoS: The EU IP DANSE approach
This paper presents some of the results of the first year of DANSE, one of
the first EU IP projects dedicated to SoS. Concretely, we offer a tool chain
that allows to specify SoS and SoS requirements at high level, and analyse them
using powerful toolsets coming from the formal verification area. At the high
level, we use UPDM, the system model provided by the british army as well as a
new type of contract based on behavioral patterns. At low level, we rely on a
powerful simulation toolset combined with recent advances from the area of
statistical model checking. The approach has been applied to a case study
developed at EADS Innovation Works.Comment: In Proceedings AiSoS 2013, arXiv:1311.319
Reactive Rules for Emergency Management
The goal of the following survey on Event-Condition-Action (ECA) Rules is to come to a common understanding and intuition on this topic within EMILI. Thus it does not give an academic overview on Event-Condition-Action Rules which would be valuable for computer scientists only. Instead the survey tries to introduce Event-Condition-Action Rules and their use for emergency management based on real-life examples from the use-cases identified in Deliverable 3.1. In this way we hope to address both, computer scientists and security experts, by showing how the Event-Condition-Action Rule technology can help to solve security issues in emergency management. The survey incorporates information from other work packages, particularly from Deliverable D3.1 and its Annexes, D4.1, D2.1 and D6.2 wherever possible
Temporal Data Modeling and Reasoning for Information Systems
Temporal knowledge representation and reasoning is a major research field in Artificial
Intelligence, in Database Systems, and in Web and Semantic Web research. The ability to
model and process time and calendar data is essential for many applications like appointment
scheduling, planning, Web services, temporal and active database systems, adaptive
Web applications, and mobile computing applications. This article aims at three complementary
goals. First, to provide with a general background in temporal data modeling
and reasoning approaches. Second, to serve as an orientation guide for further specific
reading. Third, to point to new application fields and research perspectives on temporal
knowledge representation and reasoning in the Web and Semantic Web
