A Protégé Plug-in for Defeasible Reasoning

Kody Moodley, Thomas Meyer, Ivan Varzinczak
In particular, we present a plug-in for the Protégé ontology editor which implements these algorithms for OWL ontologies.  ...  Here we recast their definitions in a defeasible DL context and define algorithms for prototypical and presumptive reasoning in defeasible DL knowledge bases.  ...  This system, known as RaMP, has been packaged as a plug-in for the popular Protégé ontology editor. The plug-in is discussed in more detail in Section 4.  ...

Conto: A Protégé Plugin for Configuring Ontologies

Andrew LeClair, Ridha Khedri
2016 Procedia Computer Science  
We introduce Conto, a Protégé plugin that overcomes this limitation by interpreting a concept as an abstract data type.  ...  However, the ontologies themselves present shortcomings in how they capture the definition of concepts of a domain.  ...  In addition to subsumption rules, defeasible reasoning aims to acquire defeasible subsumption rules 14 .  ...

2008 International journal on artificial intelligence tools  
Rules can assist in this affair and various logics have been proposed for the Semantic Web domain. One of them is defeasible reasoning that deals with incomplete and conflicting information.  ...  However, in order for the full potential of the Semantic Web to be achieved, the ability of reasoning over the available information is also essential.  ...  Acknowledgments This work was partially supported by a NON-EUROPE project (GSRT -05 NON EU 423), jointly funded by the European Union and the Greek Government (General Secretariat of Research and Technology  ...

On Rational Closure in Description Logics of Typicality [article]

Laura Giordano and Valentina Gliozzi and Nicola Olivetti and Gian Luca Pozzato
2013 arXiv   pre-print
We define the notion of rational closure in the context of Description Logics extended with a tipicality operator.  ...  We provide an ExpTime algorithm for computing the rational closure of an Abox and we show that it is sound and complete with respect to the minimal model semantics.  ...  In [18] a plug-in for the Protégé ontology editor implementing the mentioned algorithm for computing the rational closure for a TBox for OWL ontologies is described.

Logic-based technologies for multi-agent systems: a systematic literature review

Roberta Calegari, Giovanni Ciatto, Viviana Mascardi, Andrea Omicini
2020 Autonomous Agents and Multi-Agent Systems  
Given the recurring cycles in the AI history, we expect that a revamp of technologies often tagged as "classical AI"—in particular, logic-based ones—will take place in the next few years.  ...  This is why understanding the current status of logic-based technologies for MAS is nowadays of paramount importance.  ...  Technological notes: The ASTRA technology essentially consists of a plug-in for the Eclipse IDE.  ...
