In this paper we consider updates that are specified as rules and consider simple knowledge bases consisting of ground atoms. We present a translation of the rule based update specifications to extended logic programs using situation calculus notation so as to compute the updated knowledge base. We show that the updated knowledge base that we compute satisfies the update specifications and yet ...

Location estimation is a fundamental sensing task in robotic applications, where the world is uncertain, and sensors and effectors are noisy. Most systems make various assumptions about the dependencies between state variables, and especially about how these dependencies change as a result of actions. Building on a general framework by Bacchus, Halpern and Levesque for reasoning about degrees o...

We propose a model of belief and intention change over the course of a dialogue, in the case where the decisions taken during the dialogue affect the possibly conflicting goals of the agents involved. We use Situation Calculus to model the evolution of the world and an observation model to analyze the evolution of intentions and beliefs. In our formalization, utterances, that only change the be...

The situation calculus (SC) is a formalism for reasoning about action. Within SC, the notion of state of a given situation is usually characterized by the set of uents that hold in that situation. However, this concept is insuucient for system speciication. To overcome this limitation, an extension of SC is proposed, the situation and state calculus (SSC), where the concept of state is primitiv...

OBJECTIVE There are some suggestions regarding the methods of consultation practice in the literature including which case will be consulted, to whom, by which transport means, the payment methods as well as the ethical issues. There are no standards for consultations in Turkey. The standardization committee of the Federation of Turkish Pathology Societies has conducted a survey to detect the c...

It is acknowledged that one of the most critical issues facing today’s organizations concerns the substantial leaps required to methodologically structure innovation. Among other published work, some suggest that a complete rethinking of current practices is required. In this article, we propose a methodology aiming at providing controlled R&D choices based on a monitoring of the impact Solutio...

In this work we consider how to enforce norms in the Situation Calculus based programming language Golog and its relatives. We define a notion of norm compliant sequence of actions with respect to norms prescribing some actions to be forbidden or obliged (ought-to-do norms), norms prescribing that a state-condition is forbidden (oughtto-be norms) and norms that are a form of deadline. We then s...

The concept of indirectness (using of tools) in automatic problem solving is investigated, and a formal approach is suggested within the framework of the Situation Calculus. The "Robot and Box" problem serves as an illustrative example throughout the paper.
