Towards Mapping Analysis in Ontology-Based Data Access

Abstract: In this paper we study mapping analysis in ontology-based data access (OBDA), providing an initial set of foundational results for this problem. We start by defining general, language-independent notions of mapping inconsistency, mapping subsumption, and mapping redundancy in OBDA. Then, we focus on specific mapping languages for OBDA and illustrate techniques for verifying the above properties of mappings

“…We base our work (Section 3) on recent formal notions of anomalous mappings in the OBDA context [10,11]: in particular, notions of inconsistent and redundant mappings, defined both in a local and in a global version. The local notions refer to single mapping assertions, while the global ones are relative to a whole mapping collection (set of mapping assertions).…”

“…Em outras palavras, há a necessidade de oferecer algoritmos e descrições semânticas precisas dos dados trabalhados para que o computador possa interpreta-las corretamente e entregar melhores resultados (Vettor et al, 2014). Por esse motivo, vários linhas de estudos convergem e vão desde o uso de ontologias para mapear um domínio comum visando a solução do problema da integração de dados heterogêneos (Ahmed, 2008), a integração baseada em Sistemas Multi-Agentes (Sui et al, 2009) ou o acesso a informação baseado em ontologias (Civili et al, 2013;Kharlamov et al, 2013;Lembo et al, 2014).…”

“…O paradigma para a integração de dados provenientes de fontes distintas é o OBDA (Ontologybased data access), que baseia o acesso à informação por meio de ontologias sobre um mesmo domínio de conhecimento de interesse (Bienvenu et al, 2013;Civili et al, 2013;Lembo et al, 2014). Essa capacidade se dá a partir de uma arquitetura de três níveis constituída pela ontologia, fontes de dados e mapeamento entre ambas (Civili et al, 2013;Lembo et al, 2014).…”
