2017 Semantic Web Journal  
A generic and effective benchmark for reliable and comparable evaluation of the practical utility of such systems would make an important contribution to the development of ontology-based data integration  ...  This approach crucially relies on useful mappings to relate the ontology and the data, the latter being typically stored in relational databases.  ...  RODI, our mapping generation quality benchmark for Relationalto-Ontology Data Integration scenarios, addresses this challenge.  ...

Ernesto Jiménez-Ruiz, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ian Horrocks, Christoph Pinkel, Martin G. Skjæveland, Evgenij Thorstensen, Jose Mora
2015 Lecture Notes in Computer Science  
Ontologies have recently became a popular mechanism to expose relational database (RDBs) due to their ability to describe the domain of data in terms of classes and properties that are clear to domain  ...  Developing appropriate ontologies and mappings for given RDBs is a challenging and time consuming task.  ...  ran experiments with a recently released relational-to-ontology benchmark suite, RODI [28] , comparing BOOTOX to IncMap, -ontop-and MIRROR.  ...

BootOX: Bootstrapping OWL 2 Ontologies and R2RML Mappings from Relational Databases

Ernesto Jiménez-Ruiz, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ian Horrocks, Christoph Pinkel, Martin G. Skjæveland, Evgenij Thorstensen, José Mora
2015 International Semantic Web Conference  
In this demo paper we present BOOTOX, a system facilitating ontology and mapping development by their automatic extraction (i.e., bootstrapping) from relational databases.  ...  BOOTOX has a number of advantages: it allows to control the OWL 2 profile of the output ontologies, and to bootstrap complex and provenance mappings, which are beyond the W3C direct mapping specification  ...  For example, if the bootstrapped ontology is to be used in a so-called Ontology Based Data Access (OBDA) scenario where the ontology provides a virtual access layer to the data, OWL 2 QL will be chosen  ...

ProGOMap: Automatic Generation of Mappings from Property Graphs to Ontologies

Naglaa Fathy, Walaa Gad, Nagwa Badr, Mohamed Hashem
2021 IEEE Access  
PROPERTY GRAPH-TO-ONTOLOGY MAPPING GENERATION Only few approaches were proposed for mapping a Property Graph (PG) to an ontology.  ...  This paper proposes ProGOMap (Property Graph to Ontology Mapper) system that automatically generates mappings from property graphs to a domain ontology.  ...  In relationalto-ontology mapping context, a comprehensive benchmark suite, RODI, is released to evaluate R2RML mappings generated from relational databases [39] , [40] .  ...

A Novel Method to Associate Sensor Data with Domain Ontology

Jin Liu, Yihe Yang, Shengjie Shang
2019 International Journal of Data Science and Analysis  
The ontology association methods can be used to construct the semantic mapping between heterogeneous ontologies, so as to effectively determine the similarity between concepts in the ontologies.  ...  Most sensor ontologies are currently built for applications in specific domains, and these ontologies are usually heterogeneous, making it difficult to share or reuse knowledge and concepts.  ...  This mapping algorithm is also capable of querying the semantics of multiple ontologies. Pinkel et al. [38] extended the previous ontology mapping benchmark and proposed a new version of RODI.  ...

Virtual Knowledge Graphs: An Overview of Systems and Use Cases

Guohui Xiao, Linfang Ding, Benjamin Cogrel, Diego Calvanese
2019 Data Intelligence  
In this paper, we present the virtual knowledge graph (VKG) paradigm for data integration and access, also known in the literature as Ontology-based Data Access.  ...  Integrating data and providing a convenient access to them are work-intensive, expensive but essential activities, as it is critical for organizations to be data-driven to stay competitive.  ...  Mapping Bootstrappers The task of a mapping bootstrapper is to generate automatically or semi-automatically a mapping for a (relational) data source.  ...

Evaluating approaches for supervised semantic labeling [article]

Natalia Ruemmele, Yuriy Tyshetskiy, Alex Collins
2018 arXiv   pre-print
A common ontology provides a way to represent the meaning of a relational schema and can facilitate the integration of heterogeneous data sources within a domain.  ...  Semantic labeling is achieved by mapping attributes from the data sources to the classes and properties in the ontology.  ...  To define the semantics of data, we can introduce an ontology [20] . Now our goal is to map attributes from relational data sources to classes and properties in an ontology.  ...
