Building Ontologies by using Re-engineering Patterns and R2RML Mappings
نویسندگان
چکیده
The ontologization of non-ontological resources has led to the design of several specific methods, techniques and tools. Among those techniques, we have the Re-engineering Patterns. More specifically, we have the Patterns for re-engineering NORs (PR-NOR) that define a procedure that transforms the NOR terms into ontology representational primitives. Currently, the W3C RDB2RDF Working Group is at the final stage of formalizing R2RML, a language for describing mappings among RDB elements and RDF. In this paper we claim that it is possible to combine PR-NORs with R2RML mappings for building ontologies from relational database content, i.e., transforming the database content into an ontology schema by using Re-engineering Patterns and R2RML mappings.

BootOX: Bootstrapping OWL 2 Ontologies and R2RML Mappings from Relational Databases
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. Moreover, BOOTOX all...
متن کاملHow to Best Find a Partner? An Evaluation of Editing Approaches to Construct R2RML Mappings
R2RML defines a language to express mappings from relational data to RDF. That way, applications built on top of the W3C Semantic Technology stack can seamlessly integrate relational data. A major obstacle to using R2RML, though, is the effort for manually curating the mappings. In particular in scenarios that aim to map data from huge and complex relational schemata (e.g., [5]) to more abstrac...
متن کاملA Demonstration of Linked Data Source Discovery and Integration
The Linked Data cloud is an enormous repository of data, but it is difficult for users to find relevant data and integrate it into their datasets. Users can navigate datasets in the Linked Data cloud with ontologies, but they lack detailed characterization of datasets’ contents. We present an approach that leverages r2rml mappings to characterize datasets. Our demonstration shows how users can ...
متن کاملEditing R2RML Mappings Made Easy
The new W3C standard R2RML defines a language for expressing mappings from relational databases to RDF, allowing applications built on top of the W3C Semantic Technology stack to seamlessly integrate relational data. A major obstacle in using R2RML, though, is the creation and maintenance of mappings. In this demo, we present a novel R2RML mapping editor which provides a user interface to creat...
متن کاملR2RML by Assertion: A Semi-automatic Tool for Generating Customised R2RML Mappings
In this paper, we demonstrate the RBA (R2RML By Assertion) tool which automatically generates customized R2RML mappings based on a set of semantic mappings that model the relationship between the relational database schema and a target ontology in RDF. The semantic mappings are specified by a set of correspondence assertions, which are simple to understand.
