A Principled Approach to Bridging the Gap between Graph Data and their Schemas [article]

Marcelo Arenas, Gonzalo I. Diaz, Achille Fokoue, Anastasios Kementsietsidis, Kavitha Srinivas
2014 arXiv   pre-print
Although RDF graphs have schema information associated with them, in practice it is very common to find cases in which data do not fully conform to their schema.  ...  RDF graph conforms to a schema.  ...  So the question one needs to address is how to bridge the gap between these two worlds, the sorts and the respective data.  ...

A principled approach to bridging the gap between graph data and their schemas

Marcelo Arenas, Gonzalo Díaz, Achille Fokoue, Anastasios Kementsietsidis, Kavitha Srinivas
2014 Proceedings of the VLDB Endowment  
Although RDF graph data often come with an associated schema, recent studies have proven that real RDF data rarely conform to their perceived schemas.  ...  In this paper, we have approached the study of the structuredness of an RDF graph in a principled way: we propose a framework for specifying structuredness functions, which gauge the degree to which an  ...  So the question one needs to address is how to bridge the gap between these two worlds, the sorts and the respective data.  ...

Pay as you go Matching of Relational Schemata to OWL Ontologies with IncMap

Christoph Pinkel, Carsten Binnig, Evgeny Kharlamov, Peter Haase
2013 International Semantic Web Conference  
A key component of an OBDA system are mappings between the schematic elements in the ontology and their correspondences in the relational schema.  ...  Our approach is based on a novel matching technique that represents the schematic elements of an ontology and a relational schema in a unified way.  ...  IncMap therefore adds annotations in IncGraph to bridge these structural gaps. Annotations are added as inactive ref-edges which can be activated during the schema matching process.  ...

XML-based Reference Modelling: Foundations of an EPC Markup Language [chapter]

Jan Mendling, Markus Nüttgens
2004 Referenzmodellierung  
A survey on graph representation in XML languages founds the decision to model EPC processes as edge element lists.  ...  The advent of XML has forced the vendors of Business Process Modelling (BPM) tools to include respective import and export interfaces in their packages.  ...  In [ArLi03] an information-theoretic approach is presented that bridges the conceptual gap between relational and XML representations.  ...

SODA

Lukas Blunschi, Claudio Jossen, Donald Kossmann, Magdalini Mori, Kurt Stockinger
2012 Proceedings of the VLDB Endowment  
SODA bridges the gap between the business needs of analysts and the technical complexity of current data warehouses.  ...  As a consequence, more and more data has been added to the data warehouses and their schemas have become increasingly complex. These systems still work great in order to generate pre-canned reports.  ...  The metadata allows to bridge the gap between the low-level SQL implementation and the concepts typically used by business users and allows to generate the right SQL for a complex query.  ...

Querying and Searching Heterogeneous Knowledge Graphs in Real-time Linked Dataspaces [chapter]

André Freitas, Seán O'Riáin, Edward Curry
2019 Real-time Linked Dataspaces  
Search and query services within a linked dataspace do not follow a one-size-fits-all approach and utilise a range of different techniques to support different characteristics of data sources and user  ...  Introduction As the volume and variety of data sources within a dataspace grow, it becomes a semantically heterogeneous and distributed environment; this presents a significant challenge to querying the  ...  Query mechanisms with the ability to automatically bridge the gap between the user and database conceptual models are described as schema-agnostic or vocabulary-independent queries.  ...

A Metamodeling Approach to Teaching Conceptual Modeling "at Large"

Ana-Maria Ghiran, Cristina-Claudia Osman, Robert Andrei Buchmann
2019 Information Systems Development  
In the authors' university there is a challenge, with respect to Conceptual Modeling topics, of bridging the gap between bachelor-level studies and research work.  ...  The key takeaway revelation for students is that a modeling language is a knowledge schema that can be tailored and migrated for specific purposes just like a database schema, to accommodate an application  ...  This gap in understanding and abstraction is comparable to the one between "database users" (who operate with data records, while taking a system or database design for granted) and those able to migrate  ...
