On specifying database updates

Raymond Reiter
1995 The Journal of Logic Programming  
These are called frame axioms, and they specify the action invariants of the domain, i.e., those fluents unaffected by the performance of an action.  ...  We formalize database transactions in exactly the same way as actions in the artificial intelligence planning domain. This leads to a database version of the frame problem in artificial intelligence.  ...  Normally, only relatively few actions in any repertoire of actions about a world will affect the truth value of a given fluent; all other actions leave the fluent invariant, and will give rise to frame  ...

A Planning-Based Service Composition Approach for Data-Centric Workflows [chapter]

Carlos-Manuel López-Enríquez, Víctor Cuevas-Vicenttín, Genoveva Vargas-Solar, Christine Collet, José-Luis Zechinelli-Martini
2015 Lecture Notes in Computer Science  
Together, our ASASEL language and enactment engine along with our enumeration approach provide the foundation for a highly flexible mechanism for managing data-centric workflows.  ...  This paper presents a planning-based approach for the enumeration of alternative data-centric workflows specified in ASASEL (Abstract State mAchineS Execution Language), which define the coordination of  ...  Planning problems are modeled as state machines described by a set of fluents and a set of actions. A fluent is a property of an object in the world and is part of the states of the world.  ...

A Fuzzy Set Semantics for Qualitative Fluents in the Situation Calculus [chapter]

Alexander Ferrein, Stefan Schiffer, Gerhard Lakemeyer
2008 Lecture Notes in Computer Science  
Qualitative representations in general facilitate to express the knowledge of a domain expert. In this paper, we propose a semantics for qualitative fluents in the situation calculus.  ...  Especially intriguing about a fuzzy set semantics for qualitative fluents is that the qualitative ranges may overlap, and a value can, at the same time, fall into several categories.  ...  643 Software for Mobile Communication Systems.  ...

Reasoning with Qualitative Positional Information for Domestic Domains in the Situation Calculus

Stefan Schiffer, Alexander Ferrein, Gerhard Lakemeyer
2011 Journal of Intelligent and Robotic Systems  
In previous work we extended the action language Golog, which was developed for the high-level control of agents and robots, with fuzzy set-based qualitative concepts.  ...  For our domestic robot, we use the robot programming and plan language Readylog, our variant of Golog.  ...  Ferrein is supported by the Alexander von Humboldt Foundation with a Feodor Lynen fellowship.
