Foundations of instance level updates in expressive description logics

Hongkai Liu, Carsten Lutz, Maja Miličić, Frank Wolter
2011 Artificial Intelligence  
In description logic (DL), ABoxes are used for describing the state of affairs in an application domain.  ...  We analyze such basic ABox updates in several standard DLs, in particular addressing questions of expressibility and succinctness: can updated ABoxes always be expressed in the DL in which the original  ...  TBox level updates have received much less attention than instance level updates.  ...

Rule Modeling and Markup [chapter]

Gerd Wagner
2005 Lecture Notes in Computer Science  
We show how certain rules can be specified in a class diagram with the help of OCL.  ...  In this paper we address several issues of rule modeling on the basis of UML. We discuss the relationship between UML class models and OWL vocabularies.  ...  description logic semantics of OWL. − UML class diagrams can be mapped to OWL vocabularies and, in this way, obtain a logical semantics.  ...

An ontology for software component matching

Claus Pahl
2006 International Journal on Software Tools for Technology Transfer (STTT)  
A link between modal logic and description logics will prove invaluable for the provision of reasoning support for component behaviour.  ...  Matching is a central activity in the discovery and assembly of reusable software components. We investigate how ontology technologies can be utilised to support software component development.  ...  The update specification based on description logic illustrates an operation definition in terms of our ontology, see Fig. 4 illustrates this.  ...

Model-driven rule composition for event-based systems

Hannes Obweger, Josef Schiefer, Martin Suntinger, Peter Kepplinger
2011 International Journal of Business Process Integration and Management  
Event patterns are modelled in a visual decision graph from easy-to-understand pieces of pattern-detection logic, and/or from sub-level event patterns.  ...  Focusing on expressiveness as well as manageability, the proposed framework uses a model-driven approach for the rule definition, where the different aspects of a rule are specified in clearly separated  ...  The work presented in this article is part of a larger, long-term research effort aiming at the development of a rule-management system for event-based systems.  ...

A Deterministic Operational Semantics for Functional Logic Programs

Elvira Albert, Michael Hanus, Frank Huch, Javier Oliver, Germán Vidal
2002 APPIA-GULP-PRODE Joint Conference on Declarative Programming  
Starting from a "big-step" semantics in natural style which relates expressions and their evaluated results-but it is not sufficient to cover concurrency, search strategies, or to reason about costs associated  ...  to particular computations-, we define a "small-step" operational semantics which actually covers the advanced features of modern functional logic languages.  ...  For instance, an expression x + y with logical variables x and y is represented as let x = x, y = y in x + y.  ...
