“…As a motivating examp le we modify and adapt an example described in [23] Table 2 between O 1 and O 2 generated by an off-the-shelf ontology align ment system. As described in Section 2, mappings are represented as 5-tuples; for example the mapping m 1 suggests an equivalence relat ionship between the entities O 1 :Well and O 2 :Well, with confidence 0.9.…”

“…The conservativity principle has been identified for instance in [13] as an align ment wh ich allo ws the interaction between ontologies, rather than providing a new description of the do main.

Abstract-Ontology matching techniques are a solution to overcome the problem of interoperability between ontologies. However, the generated mappings suffer fro m logical defects that influence their usefulness. In this paper we present a detailed analysis of the problem socalled conservativity princip le; align ment between ontologies should never generate new knowledge compared to those generated by reasoning solely on ontologies. We also study the sub-problems; Ontology change and Satisfiability preservation problems and compare the related works and their way to detect and repair conservativity principle. At the end we present a set of open research issues.

“…For this purpose we extended an existing ontology alignment system LogMap [12] that aligns two ontologies O 1 and O 2 by deriving equivalence and subclass(property) assertions between the terms from O 1 's and O 2 's vocabularies using the lexical characteristics of the terms and the structure of the ontologies. Our extension [27] Layering. Our layering procedure uses a novel technique for the semi-automatic discovery of direct mappings between O and D by performing string matching of O and D's schemata enhanced with their structural comparison [20].…”

“…The alignment outputs a set of pairs of matched terms together with a score showing how well they match. For this purpose we extended the ontology alignment system LogMap [27], that can perform both syntactic and structural matching of ontologies, so that it also can perform the required alignment of ontologies and query catalogues. The main challenge was to define the notion of a structural neighbourhood of a query term in a set of conjunctive queries.…”

Abstract. Ontology Based Data Access (OBDA) is a prominent approach to query databases which uses an ontology to expose data in a conceptually clear manner by abstracting away from the technical schema-level details of the underlying data. The ontology is 'connected' to the data via mappings that allow to automatically translate queries posed over the ontology into data-level queries that can be executed by the underlying database management system. Despite a lot of attention from the research community, there are still few instances of real world industrial use of OBDA systems. In this work we present data access challenges in the data-intensive petroleum company Statoil and our experience in addressing these challenges with OBDA technology. In particular, we have developed a deployment module to create ontologies and mappings from relational databases in a semi-automatic fashion, and a query processing module to perform and optimise the process of translating ontological queries into data queries and their execution. Our modules have been successfully deployed and evaluated for an OBDA solution in Statoil.

The spread of high‐speed networks changes the way in which organizations manage information. Distributed environments, such as multi‐cloud environments, can be exploited by users belonging to different organizations. Companies are realizing that they can achieve significant cost savings by outsourcing some of their information technology environments to specialized service companies. This rapid transition has introduced a number of security risks and challenges. The resulting environment cannot succeed at addressing them without the use of access control policies and the definition of trust mechanisms. Access control ontologies, as a structured way to represent real word elements, are widely employed for making the security interoperable and understandable. Ontologies that have been built for this aim suffer from the lack of crucial elements for distributed environments. In this paper, we tackle the problem of trust‐based access control models. We define a list of trust elements that should be integrated into any access control ontology. We also provide a mapping technique that permits the exchange of trust information. Based on these two contributions, our reputation mechanism, that builds upon the organization‐based access control model (OrBAC), is created. To prove the efficiency of our proposal, we test it in a multi‐cloud environment. Then, we conduct a set of experiments that show the high accuracy level of our system.
