Ontology-Based Data Quality Management: Methodology, Cost, and Benefits

The competitiveness of today’s businesses strongly depends on their data, and the degree of automation in business processes. The business performance of information systems is constrained by the quality of this data. Due to the multidimensional characteristics of data quality, identification and improvement of data quality problems are complex tasks which require knowledge about what are corre...

A Note on Methodology for Designing Ontology Management Systems

In this note we propose a novel methodology for designing Ontology Management Systems architecture, which grounds on an ontology representation based on probabilistic Graphical Models. By discussing about troubles with ontology as tool for managing knowledge, formal assumptions about semantics definition and representations rise, turning out an original architecture that will be presented and dis-

A Survey on Agent-based Ontology Alignment

Ontologies today are increasingly used as consensual knowledge representations in many distributed applications. However, if a system of knowledge based nodes is decentralized, the ontologies at those nodes differ. Therefore the alignment of knowledge representations is required. One of the promising approaches to solve this heterogeneity is the use of agents for aligning knowledge representati...

NeOn Methodology for Building Ontology Networks: a Scenario-based Methodology

The 1990s and the first years of this new millennium have witnessed the growing interest of many practitioners in methodologies that support the creation of single or isolated ontologies. All these approaches have supposed a step forward since they have transformed the art of constructing single ontologies into an engineering activity. With the goal of speeding up the ontology development proce...
