On Demand SPARQL Extension: A Case Study of Extending Geo-SPARQL for Sensor Data Exploration in Semantic Cities
نویسندگان
چکیده
SPARQL is the standard language for querying on RDF data, however it lacks support for many useful functions that a semantic city service may require. In this paper, a system is discussed where functions written in commonly known programming language like Java can be instantly added to the SPARQL function library, thereby decreasing development time as well as keeping the underlying implementation transparent. As a case study for instant SPARQL extension, we have chosen to extend the Geo-SPARQL library. We propose various functionality missing in Geo-SPARQL specification and discuss how their instant addition makes sensor data exploration in semantic cities more rich.

SPARQL-ST: Extending SPARQL to Support Spatiotemporal Queries
Spatial and temporal data is plentiful on the Web, and Semantic Web technologies have the potential to make this data more accessible and more useful. Semantic Web researchers have consequently made progress towards better handling of spatial and temporal data.SPARQL, the W3C-recommended query language for RDF, does not adequately support complex spatial and temporal queries. In this work, we p...
متن کاملContinuous Queries and Real-time Analysis of Social Semantic Data with C-SPARQL
Social semantic data are becoming a reality, but apparently their streaming nature has been ignored so far. Streams, being unbounded sequences of time-varying data elements, should not be treated as persistent data to be stored “forever” and queried on demand, but rather as transient data to be consumed on the fly by queries which are registered once and for all and keep analyzing such streams,...
متن کاملSPARQL-Based Applications for RDF-Encoded Sensor Data
Complex event processing is currently more dominated by proprietary systems and vertical products than open technologies. In the future, however, internet-connected people and things moving between smart spaces in smart cities will create a huge volume of events in a multi-actor, multi-platform environment. End-user applications would benefit from the possibility for open access to all relevant...
متن کاملExtensions of SPARQL towards Heterogeneous Sources and Domain Annotations
SPARQL is the W3C Recommended query language for RDF. My current work aims at extending SPARQL in two distinct ways: (i) to allow a better integration of RDF and XML; and (ii) to define a query language for RDF extended with domain specific annotations. Transforming data between XML and RDF is a much required, but not so simple, task in the Semantic Web. The aim of (i) is to enable transparent ...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
