A lightweight approach to explore, enrich and use data with a geospatial dimension with semantic web technologies

Christophe Debruyne, Kris McGlinn, Lorraine McNerney, Declan O'Sullivan
2017 Proceedings of the Fourth International ACM Workshop on Managing and Mining Enriched Geo-Spatial Data - GeoRich '17  
In this paper, we propose a lightweight method and set of tools for: upli -transforming non-RDF resources into RDF documents; creating links between RDF datasets; client-side processing of geospatial functions  ...  With this approach, people who wish to avail of the spatial dimension in data can do so from their client (e.g., in a browser) without the need to rely on bespoke technology. is could be of great utility  ...  Technology is funded under the SFI Research Centres Programme (Grant 13/RC/2106) and is co-funded under the European Regional Development Fund. is study was also supported by the Irish Government Department of  ...

GeoSPARQL 1.1: Motivations, Details and Applications of the Decadal Update to the Most Important Geospatial LOD Standard

Nicholas J. Car, Timo Homburg
2022 ISPRS International Journal of Geo-Information  
We also describe the theory behind particular updates, initial implementations of many parts of the standard, and our expectations for GeoSPARQL 1.1's use.  ...  In 2012, the Open Geospatial Consortium published GeoSPARQL defining "an RDF/OWL ontology for [spatial] information", "SPARQL extension functions" for performing spatial operations on RDF data and "RIF  ...  Acknowledgments: We thank the individual members of the GeoSPARQL Standards Working Group for the work to update GeoSPARQL for this version 1.1.  ...

Geospatially Partitioning Public Transit Networks for Open Data Publishing

Harm Delva, Julián Andrés Rojas, Pieter Colpaert, Ruben Verborgh
2021 Journal of Web Engineering  
In our prior work we have shown that geospatially partitioning an operator's network can improve query times for client-side route planning applications by a factor of 2.4.  ...  Public transit operators often publish their open data in a data dump, but developers with limited computational resources may not have the means to process all this data efficiently.  ...  Data dumps put the data processing burden on the client's side but allow the most flexibility for clients.  ...

BimSPARQL: Domain-specific functional SPARQL extensions for querying RDF building data

Chi Zhang, Jakob Beetz, Bauke de Vries, Álvaro Sicilia, Pieter Pauwels, Leandro Madrazo, María Poveda Villalón, Jérôme Euzenat, Álvaro Sicilia, Pieter Pauwels, Leandro Madrazo, María Poveda-Villalón (+1 others)
2018 Semantic Web Journal  
Extended functions are modelled as RDF vocabularies and classified into groups for further extensions. We combine declarative rules with procedural programming to implement extended functions.  ...  Compared with query techniques developed in the conventional Building Information Modeling domain, we show the added value of such approach by providing an application example of querying building and  ...  Recently, an approach is presented in [13] to define functions by extending Triple Pattern Fragments (TPF) [55] on the client side, hence extended functions are compatible with any SPARQL server.  ...

A Novel Approach for Publishing Linked Open Geodata from National Registries with the Use of Semantically Annotated Context Dependent Web Pages

Adam Iwaniak, Marta Leszczuk, Marek Strzelecki, Francis Harvey, Iwona Kaczmarek
2017 ISPRS International Journal of Geo-Information  
Further development of this approach comes from using linked data (LD) with expert systems to support analysis functions and tasks.  ...  A number of problems are very apparent in the process of developing central data repositories and storing the data derived from the local SDI level, e.g., cadastral databases.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

A Proposal for Deploying Hybrid Knowledge Bases: the ADOxx-to-GraphDB Interoperability Case

Dimitris Karagiannis, Robert Andrei Buchmann
2018 Proceedings of the 51st Hawaii International Conference on System Sciences   unpublished
Considering the common ground of graph databases, the paper proposes an integration of OWL ontologies with diagrammatic representations as enabled by the ADOxx metamodeling platform.  ...  The proposal is based on the RDF-semantics variant of OWL and leads to a particular type of hybrid knowledge bases hosted, for proof-of-concept purposes, by the GraphDB system due to its inferencing capabilities  ...  Client-side proofs-of-concept are further necessary to bring the hybrid knowledge at end-user level, in "model-aware" front-ends.  ...
