Defeasible logic is a non-monotonic formalism that deals with incomplete and conflicting information, whereas modal the concepts of necessity possibility. These types logics play significant role in emerging Semantic Web, which enriches available Web information meaning, leading to better cooperation between end-users applications. logics, general, and, particularly, deontic provide means for modeling agent communities, where each characterized by its cognitive profile normative system, as...
This paper presents a novel, integrated platform for energy monitoring, management and savings in the context of Smart University Building. Namely, proposed International Hellenic (IHU) integrates an intelligent, rule-based agent that enforces savings, while variet y applications offers user interaction with system means monitoring management. The application layer is built over common Web Service middleware, incorporating semantic interoperability. Monitoring visualize raw aggregated sensor...
The timely and efficient cooperation across sectors borders during maritime crises is paramount for the safety of human lives. Maritime monitoring authorities are now realizing grave importance cross-sector cross-border information sharing. However, this compromised by diversity existing systems vast volumes heterogeneous data generated exchanged operations. In order to address these challenges, EU has been driving several initiatives, including EU-funded projects, facilitating exchange...
Abstract Dialogue‐based systems often consist of several components, such as communication analysis, dialogue management, domain reasoning, and language generation. In this paper, we present Converness, an ontology‐driven, rule‐based framework to facilitate reasoning for conversational awareness in multimodal dialogue‐based agents. Converness uses Web Ontology Language 2 (OWL 2) ontologies capture combine the modalities domain, example, deictic gestures spoken utterances, fuelling topic...
This paper presents a novel energy management framework for multi-agent coordination in smart buildings. The builds on top of an existing Service-Oriented middleware Ambient Intelligence, which offers sensor and actuator functions wireless devices. also provides semantics infrastructure that assists authoring agent policies reducing consumption maximizing user comfort. Each within the is responsible monitoring environmental context controlling electrical appliances specific room. However,...
