To solve the problem of using information to control behavior for unmanned underwater vehicle (UUV), this paper presents a situation awareness method on the basis of ontology. During the period of UUV operation, situation perceived information is more important for the safety of UUV and therefore, real-time and accurate perception of the situation has an important impact on UUV autonomous decision...
In this paper we propose a novel concept of human-machine-environment cyber-physical system (HME-CPS) in smart homes to support independent living of elderly and physically disabled people. Within this system, a hierarchical task planning approach is developed on purpose of combining qualitative reasoning and quantitative calculation via bidirectional data exchanges between C++ and Prolog. A group...
Energy-saving offices require autonomous and optimised control of integrated devices and appliances with the objective of saving energy while the occupant comfort and productivity are preserved. We propose an approach that analyses and controls an office space and accounts for the objectives of energy-saving offices. The approach considers ontology-based occupant activity recognition using simple...
Surveillance typically involves monitoring humans, buildings, and other mobile objects to detect abnormal behavior; primarily to sense and detect any anomalies in real time. Conventionally this has been done manually, but with a growing demand for day-to-day surveillance and the need for intense monitoring; decision support has proven to improve the overall system performance. Decision support also...
The main knowledge management challenges are to capture, store and reuse contextual knowledge generated during interactions that occur daily in an organization. In this paper, we propose an activity context-aware architecture to support knowledge management in working processes. The required features for this architecture are processing, reasoning and sharing contextual knowledge involving information...
In this paper we present a causal artificial intelligence design (CAID) theory that borrows notions from classical philosophy for modeling intelligent agents. Principles introduced by this theory are used for extending a goal-driven BDI architecture and implementing what we call causal agent. This architecture incorporates causal formalisms like Pearl's Do calculus and C+ which are adapted to Semantic...
Robotic platforms are helping marine applications to gain routine and permanent access to the underwater environment. However, challenges related to this domain require the development and integration of more evolved embedded tools that can raise the platform's autonomy levels while maintaining the trust of the operator. This paper shows how knowledge representation, reasoning and planning tools can...
The insider threat has assumed increasing importance as our dependence on critical cyber information infrastructure has increased. In this paper we describe an approach for thwarting and attributing insider attacks. The Sense, Prepare, Detect, and React (SPDR) approach utilizes both a highly intelligent software reasoning system to anticipate, recognize, respond to, and attribute attacks as well as...
We claim that a key feature for correct and effective web service composition, and one that has largely been ignored,is the joint consideration of (semantic) causal links and causal laws, respectively in area of description logics (DL) and AI planning. In this paper we propose a means of specifying both causal links and laws into Web service composition by integrating DL reasoning and situation calculus...
