Dynamic Obligation Hierarchies
نویسندگان
چکیده
Typically agents have obligations of diiering importance. Consequently we give a hierarchical deenition of obligations, according to which an agent's obligations form a coherent hierarchy and new obligations are de-ned with reference to it. We then show how preferential entailment can be used to formalise the persistence and revision of obligation hierarchies.

A Logical Analysis of the Relationship between Commitment and Obligation
In this paper, we analyze the relationship between commitment and obligation from a logical viewpoint. The principle of commitment implying obligation is proven in a specific logic of action preference which is a generalization of Meyer’s dynamic deontic logic. In the proposed formalism, an agent’s commitment to goals is considered as a special kind of actions which can change her deontic prefe...
متن کاملThe Fragility of Individual-Based Explanations of Social Hierarchies: A Test Using Animal Pecking Orders
The standard approach in accounting for hierarchical differentiation in biology and the social sciences considers a hierarchy as a static distribution of individuals possessing differing amounts of some valued commodity, assumes that the hierarchy is generated by micro-level processes involving individuals, and attempts to reverse engineer the processes that produced the hierarchy. However, suf...
متن کاملDynamic Generation and Reenement of Concept Hierarchies for Knowledge Discovery in Databases
Concept hierarchies organize data and concepts in hierarchical forms or in certain partial order, which helps expressing knowledge and data relationships in databases in concise, high level terms, and thus, plays an important role in knowledge discovery processes. Concept hierarchies could be provided by knowledge engineers, domain experts or users, or embedded in some data relations. However, ...
متن کاملOptimised coupling of hierarchies in image registration
Image registration algorithms rely on multilevel strategies in order to improve efficiency and robustness. Hierarchies in image resolution, the underlying grids for spline-based transformations, as well as the regularisation parameters are used. This paper deals with the optimisation of the coupling of these hierarchies. An image registration procedure – suitable for 2D polyacrylamide gel elect...
