Networks of ontologies and alignments

چکیده
Part of these notes have been extracted from [10] and hence have benefited from in-depth discussions with Pavel Shvaiko. Other parts of them are results from Antoine Zimmermann’s PhD dissertation [19]. And now much of them is original.

Revision in networks of ontologies
Networks of ontologies are made of a collection of logic theories, called ontologies, related by alignments. They arise naturally in distributed contexts in which theories are developed and maintained independently, such as the semantic web. In networks of ontologies, inconsistency can come from two different sources: local inconsistency in a particular ontology or alignment, and global inconsi...
متن کاملThe category of networks of ontologies
The semantic web has led to the deployment of ontologies on the web connected through various relations and, in particular, alignments of their vocabularies. There exists several semantics for alignments which make difficult interoperation between different interpretation of networks of ontologies. Here we present an abstraction of these semantics which allows for defining the notions of closur...
متن کاملFoundations for Revising Networks of Ontologies
The framework of belief revision has been studied for years in the context of logic theories. It has been considered several times for description logics and more recently for aligned ontologies. We consider more generally the problem of revising a network of ontologies: given a set of ontologies connected by alignments, how to evolve them such that they account for new information, i.e., new f...
متن کاملInteraction-based ontology alignment repair with expansion and relaxation
Agents may use ontology alignments to communicate when they represent knowledge with different ontologies: alignments help reclassifying objects from one ontology to the other. These alignments may not be perfectly correct, yet agents have to proceed. They can take advantage of their experience in order to evolve alignments: upon communication failure, they will adapt the alignments to avoid re...
متن کاملDRAOn: A Distributed Reasoner for Aligned Ontologies
DRAOn is a distributed reasoner which offers inference services for a network of OWL ontologies correlated by alignments. Reasoning with such networks of ontologies depends on the semantics we define for alignments with respect to ontologies. DRAOn supports two semantics for a network of ontologies: the standard Description Logics (DL) semantics for non-distributed reasoning, and the Integrated...
متن کاملExploiting ontologies and alignments for trust in semantic P2P networks
In a semantic P2P network, peers use separate ontologies and rely on alignments between their ontologies for translating queries. However, alignments may be limited —unsound or incomplete— and generate flawed translations, and thereby produce unsatisfactory answers. In this paper we propose a trust mechanism that can assist peers to select those in the network that are better suited to answer t...
