چکیده

It often happens that different references (i.e. data descriptions), possibly coming from different heterogeneous data sources, concern the same real world entity. In such cases, it is necessary: (i) to detect, through reconciliation methods, whether different data descriptions refer to the same real world entity and (ii) to fuse them into a unique representation. Here we assume the reference reconciliation is solved, and we propose a fusion method based on possibility theory, able to cope with uncertainty and with ontological knowledge. An implementation using W3C standards is provided. Rising from the fusion process, an ontology enrichment procedure is proposed to complete the global ontology.

Using Syntactic Possibilistic Fusion for Modeling Optimal Optimistic Qualitative Decision

This paper describes the use of syntactical data fusion to computing possibilistic qualitative decisions. More precisely qualitative possibilistic decisions can be viewed as a data fusion problem of two particular possibility distributions (or possibilistic knowledge bases): the first one representing the beliefs of an agent and the second one representing the qualitative utility. The proposed ...

Reasoning with multiple-source information in a possibilistic logic framework

This paper addresses the problem of merging uncertain information in the framework of possibilistic logic. It presents several syntactic combination rules to merge possibilistic knowledge bases, provided by different sources, into a new possibilistic knowledge base. These combination rules are first described at the meta-level outside the language of possibilistic logic. Next, an extension of p...

Generating Ontologies from Relational Data with Fuzzy-Syllogistic Reasoning

Existing standards for crisp description logics facilitate information exchange between systems that reason with crisp ontologies. Applications with probabilistic or possibilistic extensions of ontologies and reasoners promise to capture more information, because they can deal with more uncertainties or vagueness of information. However, since there are no standards for either extension, inform...

A Modal Logic for Reasoning about Possibilistic Belief Fusion

In this paper, we propose a modal logic for reasoning about possibilistic belief fusion. This is a combination of multiagent epistemic logic and possibilistic logic. We use graded epistemic operators to represent agents’ uncertain beliefs, and the operators are interpreted in accordance with possibilistic semantics. We employ ordered fusion based on a level skipping strategy to resolve the inco...

Merging Incommensurable Possibilistic DL-Lite Assertional Bases

This short paper studies the problem of merging of different independent data sources linked to a lightweight ontology under the incommensurability assumption. In general, data are often provided by several and potentially conflicting sources of information having different levels of priority. To encode prioritized assertional bases, we use possibilistic DLLite logic. We investigate an egalitar...
