Normative conflict resolution in multi-agent systems
TL;DR: In this paper, the authors present mechanisms for detecting and resolution of normative conflicts, based on first-order unification and constraint solving techniques, are the building blocks of more sophisticated algorithms for the management of normative positions, that is, the adoption and removal of permissions, obligations and prohibitions in societies of agents.

TL;DR: This paper approaches the sensor-mission assignment problem from a Semantic Web perspective and proposes a set of ontologies describing mission tasks, sensors, and deployment platforms that are used to constrain a search for available instances of sensors and platforms that can be allocated at mission execution-time to the relevant tasks.
Book ChapterDOI
OntoSearch: An Ontology Search Engine
TL;DR: The work on OntoSearch, a kind of “ontology Google”, which can help users find ontologies on the Internet, is discussed, which combines Google Web APIs with a hierarchy visualization technique.
Proceedings ArticleDOI
Resolving conflict and inconsistency in norm-regulated virtual organizations
TL;DR: This work introduces an approach, based on first-order unification, to detect and resolve conflicts and inconsistencies inNorm-governed virtual organizations, and can capture a useful notion of inter-agent (and inter-role) delegation of actions and norms associated to them, and use it to address conflicts/inconsistencies caused by action delegation.
Journal ArticleDOI
Constraint rule-based programming of norms for electronic institutions
TL;DR: This paper proposes a rule language to specify and explicitly manage the normative positions of agents (permissions, prohibitions and obligations), with which distinct deontic notions and their relationships can be captured.
