Watermarking for ontologies

2011

In this paper, we study watermarking methods to prove the ownership of an ontology. Different from existing approaches, we propose to watermark not by altering existing statements, but by removing them. Thereby, our approach does not introduce false statements into the ontology. We show how ownership of ontologies can be established with provably tight probability bounds, even if only parts of the ontology are being re-used. We finally demonstrate the viability of our approach on real-world ontologies.

Paesaggi e virtualità: il caso dei videogiochi open world

2021

Il capitolo prende in considerazione il caso di tre recenti videogiochi che, (ri)producendo peculiari forme di spazialità, costruiscono complessi paesaggi virtuali e sistemi di interazioni multistratificate al fine di sviluppare una riflessione dalla prospettiva della geografia culturale. Tutti e tre rientrano (anche se con sfumature diverse) nello stesso genere, denominato "open world" oppure "free roaming", termini che fanno riferimento alla modalità di gioco, incentrata soprattutto sull’esplorazione di un “mondo” virtuale

OWL Orthogonal Extension

2012

It is critical for knowledge bases to capture the reality in direct and intuitive way. OWL ontology language was designed for this goal. In this paper we study the limitations of the OWL open world semantics for the task of knowledge capture and retrieval. We propose a new mechanism based on the closed world semantics that alleviates part of the limitations. Further we describe a system where both OWL and the new mechanisms interoperate together. Finally, we outline some immediate applications and further research directions.
