A lightweight approach to explore, enrich and use data with a geospatial dimension with semantic web technologies
2017
Proceedings of the Fourth International ACM Workshop on Managing and Mining Enriched Geo-Spatial Data - GeoRich '17
Preserved Fulltext
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 ...

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. ...

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. ...

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. ...
